Guided identification
Identify a Gemstone With Structured Property Matching
Use this interactive system to narrow possibilities by selecting observed physical properties and comparing them with our gemstone database.
How to Identify Your Gemstone
Built as an educational resource and collector reference, this tool helps you run a practical identification workflow before moving to full profile review.
Observe the Colour
Look at the primary and secondary colours of your gemstone. Select all colours that apply.
Check Transparency
Hold it up to light. Can you see through it clearly (transparent), partially (translucent), or not at all (opaque)?
Test Hardness
Try scratching with common objects: fingernail (2.5), copper coin (3.5), glass (5.5), steel knife (6.5). This tells you the approximate hardness.
Examine Crystal Shape
Look at the visible crystal structure. Is it cubic, hexagonal, or another shape? Some stones may be amorphous (no visible structure).
Assess Lustre
How does the surface shine? Is it glass-like, metallic, pearly, silky, waxy, or dull?
Use this matching tool to identify unknown stones. Select as many characteristics as you know. The system will match gemstones based on shared properties.
For best results, combine colour, transparency, hardness range, crystal system, lustre, and any visible optical effects.

Identification Tips
- Hardness Scale: Mohs hardness ranges from 1 to 10. Softer stones need protective settings, while harder stones are usually suitable for daily wear.
- Transparency Types: Transparent stones allow clear visibility; translucent stones glow when backlit; opaque stones block light.
- Crystal Systems: Different gems form in different crystal systems, which helps narrow likely candidates.
- Lustre: Lustre describes how light reflects from a gemstone surface.
- Combine Signals: The most accurate identification comes from combining multiple observed properties.
Gemstone Identification FAQ
Can this tool identify my gemstone with one filter?
Single-property filtering gives a broad shortlist. For stronger matches, combine colour with hardness, transparency, and crystal system.
Which details improve matching accuracy most?
Hardness range, transparency, and crystal system usually reduce uncertainty fastest, especially when used alongside colour and lustre.
What should I do after finding likely matches?
Open each gemstone profile to compare formation, uses, care guidance, and related stones before making a final judgement.
