A gem identifier helps distinguish gemstones such as sapphire, emerald, spinel, and quartz varieties from a photo or property checklist. RockScan combines camera identification with collector directory cards for gemstones.

Why collectors use RockScan
- Gem identifier by picture for jewelry and loose stones
- Trade-aware notes on treatments and lookalikes
- Works alongside crystal identifier and rock identifier intents
Gem identifier by picture
Snap a picture in diffuse daylight to try gem identifier photo ID. Fill the frame with one stone, include a coin for scale, and shoot a dry face plus a lightly damp corner so color and transparency read clearly. Open the result in the online studio or the rock identifier app.

Lookalikes gem collectors confuse
- Quartz vs glass: quartz is Mohs 7 with no bubbles; glass is softer and often shows bubbles or mold lines.
- Amethyst vs purple fluorite: amethyst holds hardness 7; fluorite (~4) scratches easily — compare amethyst vs fluorite.
- Opal vs plastic/glass: natural opal shows play-of-color in layers; fakes often look painted or uniform — see opal.
- Jade vs serpentine/glass: jade feels dense and tough; glass chips differently — start with jade and turquoise cards.
Browse the crystals hub for photo-friendly varieties — labradorite flash, moonstone billow — or clear definitions at rock vs mineral vs crystal.
