A diamond set in a ring, a clear crystal resting in a palm, a tiny pearl decorating a hair ornament. Gemstone motifs on their own make an image more elegant and more magical. Rinka can never resist anything sparkly either. In this article I'll introduce the main gemstone and mineral tags, plus tips for bringing out their shine and transparency.
Start with the classic gemstone tags
Gemstones have clear colors, and AI is very good at drawing them. Just entering the name settles the color and texture, so learn the main gemstones first. They also work great as a substitute for color tags.
Mineral and crystal tags
Beyond cut gemstones, using raw stones and crystals adds a fantasy feel and a natural sense of mystery. They're easy to use as backgrounds and props too, so they're very handy for setting the mood.
- To add transparency, include transparent or translucent
- To make something glow from within, glowing crystal is handy
- Express the rough texture of raw stone with geode or raw gemstone
Lighting that brings out sparkle and transparency
The charm of gemstones is, above all, how they reflect and glitter in the light. Just the stone's name looks pretty, but adding light-focused tags makes them look much more real. Highlights and transparency are the two key points.
For strong reflections, sparkle and shiny work well, and for the glitter of the facets, gemstone facets is effective. To strengthen the see-through feel, try adding transparent or light refraction.
Using gems as accessories and background motifs
Besides drawing gems on their own, working them into accessories or backgrounds expands the world. Set in a necklace or crown they look noble, floating in the background they look magical; you can use them however you like.

Finally, here's how to think about color to make the most of gemstones. Gems already carry star-level colors on their own, so the trick is to calm the surrounding colors down. Keep this in mind and the stones will stand out.
Rinka's tips
- When a gem is the star, make the background dark or pale and use sparkle and highlight so only the stone shines; that draws the eye
- When lining up several gems, either keep them in the same color family or add just one complementary color so it stays elegant instead of cluttered
FAQ
Frequently Asked Questions
My gems don't sparkle and just look like blobs of color.
In addition to the stone's name (diamond, crystal, etc.), try adding sparkle, highlight and shiny. For clear stones, adding transparent or light refraction gives the feeling of light bending inside and makes them look real right away. Darkening the background a little makes the shine stand out even more.
I want dreamy, fantasy-style gemstones.
Using glowing crystal or prismatic light gives you mysterious crystals that glow from within. Scattering geode or crystal cluster in the background creates a cave-like fantasy world. Keeping to blue-purple tones (amethyst, aquamarine) makes the image even more dreamlike.
I want the character to wear gems naturally as accessories.
The trick is to build around jewelry and specify concretely with gem name plus accessory name, like diamond necklace or pearl earrings. An upper-body composition (upper body) shows off accessories around the face nicely. Adding shiny or highlight brings out the luster of metal and stone for a more luxurious feel.
