Can You Wear A With B? Crystal Pairing Checker
Two stones, one verdict: whether they can share a wrist, and what to do if they cannot. Covers 39 stones.
Birthstone Calculator
All twelve months with hardness, ring-safety, the modern additions and the budget alternative for each.
Is My Crystal Real? Fake Crystal Checker
Sorts a suspect stone into glass, treated or seller-risk - three different answers that call for three different responses.
Crystal Finder by Budget and Wear
Budget, wear, hand use and colour in - stones that survive all four out, with the treatments to avoid.
What these tools do and do not do
Every tool on this page runs in your browser and is built from the same stone data we use to write the guides: hardness ranges, wear ratings, treatment notes and water tolerance. They answer physical questions - can this scratch that, which stone fits this budget, which birthstone suits a ring - and they deliberately do not answer questions about energy, healing or which stone is right for your mood. That is not a gap in the tools, it is the boundary this site works inside. If a result ever contradicts what a seller tells you about a stone, treat the seller as the one who has something to sell.
Looking a stone up rather than running a check?
The crystal gallery puts all 39 stones on one page with their hardness, everyday-wear rating and water tolerance, plus a full record behind each card: treatments to expect, what is most often sold in its place, and price bands by form. Every tool here reads the same data file, so a number you see in the gallery is the number the tool will use.

Disclaimer
This is reference information for buying, wearing and caring for stones, not a laboratory identification and not medical advice. Hardness values follow standard mineralogy and a given piece can behave differently if it is treated, fractured or unusually thin. For anything you intend to put in your mouth, on broken skin or in a container of drinking water, treat a jeweller's or a mineralogist's in-person assessment as the only reliable answer.
