You found a gorgeous coloring page dripping with jewels, crystals, and ornate settings. Your pencils are ready. But the moment you hover over that first gem, your brain screams: don’t mess it up. Sound familiar? This post is your safety net. We’re going to walk through exactly how to color gemstones with colored pencils, from smooth cabochons to multi-faceted brilliants, in a way that builds your confidence one tiny stone at a time.
Start Here: How To Practice Gemstones Without Ruining Your Favorite Page
Let’s get one thing out of the way: you are not going to touch your favorite coloring page yet. Not today. Instead, you’re going to practice off the page. Photocopy a gem from your book, print grayscale clips from public-domain art, or just sketch simple circles and ovals on scrap paper. That’s your playground.
Before you commit to any illustration, try doing tiny five-to-ten-minute gemstone drills. Pick one thing to focus on per drill: maybe it’s placing a light source, maybe it’s blending two colors smoothly, maybe it’s adding a single sparkle. One thing. That’s it.
Use the cheapest paper you have. The back of old prints works perfectly for gemstone experiments. The goal is to strip away the anxiety so your hand can learn without your brain panicking. YouTube has numerous tutorials for coloring gemstones that you can watch alongside these drills for extra guidance.
At It’s Easy To Draw, every gemstone lesson is built on this safe-practice approach: warm-ups first, masterpiece later.
Tools You Need To Color Gemstones With Colored Pencils
You don’t need a huge studio. A small pencil set and a hard surface are enough to start coloring gems today. Here’s what to gather:
Core pencils:
- A set of at least 24 artist or student grade colored pencils
- A white pencil for highlights
- A very dark pencil (indigo or black) for deepest shadows
- A colorless blender pencil or a light pencil of the same hue for smoothing
Paper: Smooth Bristol or quality coloring book paper works best for faceted gemstones. Paper tooth matters: too much texture creates rough highlights and fuzzy edges; too smooth and pigment won’t grip. Aim for a medium-smooth surface that holds detail.
Support tools:
- Kneaded eraser for lifting pigment
- Pencil sharpener (sharp points are non-negotiable for crisp facets)
- Soft brush or tissue for dust removal
- Optional masking tape for clean edges around gems
Starter palette for gems: cool blues and teals, emerald greens, ruby reds, amethyst purples, plus a couple of warm and cool greys for neutral diamonds.
Any brand works. Smoother, wax-based pencils like Prismacolor pencils layer quickly and produce rich saturation. Oil-based pencils like Polychromos keep facets sharper with less wax buildup. Experiment and see what your hand prefers.
Gemstone Basics: Understanding Facets, Light, And Color
Realistic coloring gemstones starts with understanding what you’re actually looking at, not just copying random shine marks from a reference picture.
Simple anatomy: Faceted gems have three main parts: the crown (upper portion above the middle), the girdle (the rim running around the widest point), and the pavilion (the lower cone-shaped section). Sitting on top of the crown is the table, the flat top facet where most light enters and exits.
How light travels: Light enters through the crown, bounces around inside the pavilion, and exits as bright shapes and dark patches. This is why gems don’t look like smooth gradients. They look “cut up” into chunks of color and shadow, because each facet breaks the light at a different angle. Research from the Gemological Institute of America shows that a gem’s face-up brilliance depends heavily on high contrast between neighboring facets: bright next to dark is what makes your eye perceive sparkle.
Transparent vs opaque: Transparent gems like diamond and topaz refract light internally, creating color shifts and fire. Semi-opaque stones like turquoise and opal rely more on surface color and less on internal shine. This distinction changes your entire coloring approach.
A helpful aside on real gems: In the jewelry world, color enhancement is a standard practice. Gemstone treatments are processes that enhance appearance, durability, or value. Common techniques to enhance gemstone color include heat treatment, irradiation, dyeing, and coating. Heat treatment is the most prevalent color enhancement method for gemstones, and the durability of heat-treated gemstones is usually permanent. Irradiation uses controlled radiation to change the color of gemstones. Dyeing introduces color pigments into porous stones to saturate or change color, though dyeing can dramatically change appearance but is generally less valuable than natural color. Coating involves applying a very thin colored film to the gemstone surface. Professional methods for gemstone treatment detection include spectroscopy and chemical analysis, and disclosure of treatments is considered an essential ethical standard in the gem trade. Why does this matter to you as an artist? Because understanding that real gems are rarely one flat, perfect hue gives you permission to layer multiple colors, add unexpected tints, and create depth that mirrors how actual stones behave in life.
Overcoming The Fear: Mindset Tips Before You Color Gems
“This page feels too precious to touch.” Nearly every adult colorist has thought this. Acknowledge it, then move past it.
The fix is low-stakes repetition: commit to coloring the same gem shape three to five times on scrap before you ever touch the actual coloring book page. By round three, your hand already knows the motions.
Start every gem with light initial layers using erasable or very pale pencils. Nothing is final in the first ten minutes. You’re mapping, not committing. Try creating a gemstone “test swatch margin” on the same sheet as your main art. A small corner where you check color combinations and pressure before going all-in.
Keep one dedicated gemstone sketchbook where messy experiments are not only allowed but expected. Fill it with ugly attempts. That’s where the learning lives.
In our How to Use Colored Pencils Like a Pro course, we build in revision passes throughout every project. You don’t chase perfection in one layer, and neither should you.
Planning Your Gem: Light Source, Shape, And Color Choices
Thirty seconds of planning saves a lot of erasing and muddy color later. Trust me on this.
Pick a single clear light source. Top-left, top-right, or directly above. Circle it on your page margin so you don’t forget halfway through. Amanda Rose Rambo offers video tutorials on gemstone coloring, and Amanda’s video explains light source effects on gemstones beautifully. The light source impacts how you color gemstones more than almost any other decision you’ll make.
Map the light on common shapes:
Shape | Highlight zone | Midtone zone | Darkest zone |
|---|---|---|---|
Circle (cabochon) | Upper-left curve | Center band | Lower-right edge |
Round faceted | Table + upper crown facets | Side crown facets | Pavilion facets |
Oval | Top third | Middle band | Bottom curve |
Heart | Upper lobes | Center body | Bottom point |
Choose a color family: cool tones (sapphire, emerald) versus warm tones (ruby, citrine). This affects background and metal setting choices later.
Build a three-color recipe: light version of the hue, mid version, dark version, plus a deep cool pencil like indigo or dark purple for the deepest shadow. Keep a small card of your favorite color gem combinations, but always experiment beyond rigid lists.
Step‑By‑Step: Coloring A Smooth Cabochon Gemstone
This section walks through a simple round cabochon, ideal for nervous beginners and coloring books packed with ornate jewelry.
Step 1: Outline lightly. Sketch or trace a circle or oval gem shape. Outline with a mid-tone pencil instead of heavy black. Keep those edges clean.
Step 2: Base layer. Block in the lightest base color using light pressure and even strokes. Leave the brightest highlight area almost white. Cover gently. Don’t press.
Step 3: Build the midtone. Deepen one side with a mid-tone color, curving your strokes along the gem’s rounded shape. Follow the form. This isn’t flat scribbling; it’s sculpting with color.
Step 4: Add the dark band. Place a band of dark value opposite the main highlight, keeping an arc shape. This suggests light passing through the stone and pooling on the far side. A touch of purple or indigo in this shadow area enriches the depth enormously.
Step 5: Blend and sharpen. Use a colorless blender or light pencil to smooth transitions. Then go back and re-sharpen the edges of your highlight and shadow. This contrast between smooth gradients and crisp borders is what makes a cabochon look glossy.
Finishing touches: Add tiny white pencil or gel pen sparkles at the highlight peak. Draw a thin dark halo around the base to “sit” the gem onto its setting. If it’s resting on a flat surface, add a soft cast shadow beneath it.
Step‑By‑Step: Coloring Faceted Gemstones (Round, Emerald, Heart)
Faceted gemstones look complicated, but they’re just flat shapes filled with value patterns. Once the drawing is in place, the coloring is a puzzle, not a mystery.
Start by lightly tracing or drawing a simple faceted template. Use a ruler or a pre-printed page. Keep lines clear but faint. Brilliant cut diamonds have eight sides on their table, which creates that classic star pattern of light and dark you’ve probably admired.
Step 1: Group your facets. Choose and mark two to three facet groups that will be brightest, middle, and darkest, based on your light direction. Use high contrast colors for vibrant gemstones. The bigger the value jump between neighbors, the more alive the stone feels.
Step 2: Pale wash. Lay down a very light wash of the lightest color across most facets, skipping the sharpest highlights entirely.
Step 3: Checkerboard midtones. Build mid-tones in alternating facets to create a checkerboard of light and dark shapes instead of gradients. Keep edges neat. Sharpen your pencil constantly.
Step 4: Deep shadows. Add deep shade in select facets near the girdle and pavilion using the darkest color plus a touch of indigo or dark purple for depth.
Step 5: Refine the table. The table facet needs the strongest contrast. Make one edge bright and the opposite edge dark to show how the crown tilts toward the light.
Adjustments for different cuts: Emerald cut gems have a slightly rounded crown and pavilion, so soften your facet edges slightly. Heart-shaped gems require angling the crown for a raised table, with the brightest facets near the top lobes and darkest near the point.
Our Colored Pencil Gemstones: The Most Comprehensive Course walks through these shapes slowly on video, but here the focus is on understanding the pattern of light and dark.
Blending, Layering, And Colored Pencil Techniques For Luminous Gems
Gemstone brilliance comes from clean layers and controlled pressure, not from pressing hard from the start. If you’re new to this medium, mastering core colored pencil techniques like layering and pressure control will make every gem you color look more polished. Separate layers for each color help manage changes easily, so resist the urge to rush.
Three blending methods compared:
Method | Best for | Watch out for |
|---|---|---|
Light-pressure layering | Building gradual depth | Can feel slow |
Burnishing (heavy pressure) | Final glossy finish | Flattens paper tooth, hard to add more |
Colorless blender | Smoothing transitions | Can push pigment around unevenly |
Use directional strokes that follow the gemstone’s curve for cabochons or align with facet edges for cut stones. This keeps the texture believable and prevents that “scribbled” look. |
On darker papers, try a white pencil underpainting: lightly fill the gem shape with white before adding color. This boosts glow effects, especially for light gems like diamonds or pale pink stones.
A critical warning: do not over-blend across facet edges. Some sharp transitions must stay crisp for a faceted look. Internal gradients belong in smooth gems, not between neighboring facets. You can also use transparent watercolor brushes for shading gemstones if you work with water-soluble pencils, but keep your strokes controlled.
Quick drills: Fill rows of tiny circles with smooth gradients, and rows of triangles with sharp light and dark splits. These warm-ups train your hand before you tackle real gemstones.
Color Recipes: How To Color Different Types Of Color Gems
Think of these recipes as starting points, not rigid formulas. Gemstones can be colored in various shades like green, blue, and pink, and every pencil brand renders hues differently. Adapt to what’s in your hand.
Generic recipe structure: light color → mid color → dark color → deep cool shadow color.
Gem | Light | Mid | Dark | Shadow |
|---|---|---|---|---|
Emerald | Light aqua-green | Mid emerald green | Deep pine green | Indigo |
Sapphire | Pale sky blue | Royal blue | Dark ultramarine | Violet |
Ruby | Soft cool red | Broad mid red | Crimson | Deep magenta |
Amethyst | Lavender | Violet | Deep purple | Blue-black |
Diamond | Light cool grey | Mid grey | Dark grey | Reflected ambient colors |
Mood through shadow temperature: cool shadows create icy, fantasy gems. Warm shadows give cozy, vintage jewelry illustrations. Build a personal “color gems chart” by filling small gem shapes with tested combinations and writing pencil names next to each. Keep this chart in your sketchbook as a living reference. Over time, it becomes your custom paint-by-number guide.
Adding Realism: Reflections, Backgrounds, And Settings Around Your Gems
Even perfectly colored gemstones can look flat if the background and metal setting don’t support the illusion.
Metal settings: A soft gold ring around a gem, a silver bezel, or tiny prongs framing the stone all help define its edges. Use high contrast and sharp highlights on metal: bright white streaks next to deep dark tones. If you want to explore metal rendering in detail, our Metallic Effects: Gold, Silver, Copper, Bronze course covers every imaginable finish.
Reflected color: Real gemstones pick up color from their surroundings. Adding faint hints of a nearby element, like a warm golden tint from a setting or a cool ambient tone from a background, into the lower facets makes your gem feel grounded in its world.
Background contrast matters:
- Dark backgrounds make pale or neon gems glow
- Light pastel backgrounds suit darker, saturated stones
- A simple gradient behind a gem adds atmosphere without overwhelming the page
Experiment with soft bokeh dots, tiny sparkle marks, or simple gradients behind your gems. Keep the style consistent with the rest of your illustration. And don’t forget the anchoring shadow: a small cast shadow beneath the stone stops it from looking like it’s floating in space.
Final Details: Sparkle, Highlights, And Finishing Touches
The magic happens in the final five to ten minutes, where careful highlights and small corrections sell the entire gemstone effect.
Reserving or restoring highlights: Use a sharp white colored pencil, a white gel pen, or simply leave the paper white from the start for the brightest spots. A white gel pen is especially powerful for adding tiny starburst sparkles over dark, saturated areas. Those little dots of light capture the eye immediately.
Add double highlights or reflected “window” shapes to mimic studio light reflections on polished stones. These final details are minimal but deliberate.
Sharpening edges: Gently reinforce the darkest creases between facets and around the girdle with a sharp dark pencil. This sharpens the faceted look without outlining everything in heavy black.
Cleanup pass:
- Lift excess wax with a kneaded eraser on any dull areas
- Tidy halos around the gemstone with a brush or eraser
- Soften accidental harsh lines with a light pencil pass
- Check for wax bloom and buff gently if needed
In our It’s Easy To Draw gemstone classes, we do a dedicated final details pass on camera so students can watch exactly how minimal but intentional these finishing marks are. A few dots of white, a re-sharpened edge, one last deep shadow line, and suddenly the stone has shine.
Practice Plans, Common Mistakes, And Next Steps With It’s Easy To Draw
Coloring gems well is a skill built over dozens of small stones, not one perfect page. Every attempt teaches your hand something new, so search for progress, not perfection. Practice on spare paper before coloring final pieces, always.
Simple 7-day practice plan:
Day | Focus | Subject |
|---|---|---|
1 | Light source drills | Circles with highlight/shadow zones |
2 | Smooth gradients | Cabochon gems |
3 | Facet value patterns | Round brilliant in blue |
4 | Complex cuts | Emerald and heart shapes |
5 | Ambient reflections | Gems with colored backgrounds |
6 | Finishing touches | Sparkles, edges, cleanup |
7 | Personal recipes | Build your color gems chart |
Common mistakes and fixes:
- Pressing too hard too soon → Build pressure gradually across four to eight layers
- Every facet the same value → Plan a checkerboard of light and dark before you start
- Muddy colors from random mixing → Limit each gem to three or four main colors plus one shadow tone
- Ignoring the light direction → Mark it on your page margin and check it constantly
