Crystal Index is a reference guide and personal collection manager for crystals and stones. Browse the encyclopaedia, save the pieces you own, add photos, record where each one came from, and keep your collection organised.
Use it as a practical library: search by name, colour, category, origin, element, zodiac association, and visual features. The optional identifier can help narrow down possible matches from a photo, then you can compare results against the reference entry.
