Mohs Scale
The Mohs scale measures gemstone scratch resistance from 1 (softest) to 10 (hardest). These guidelines are helpful in broad strokes. We can also advise on the best type of settings and jewellery types for this gemstone and/or design for protection.
8-10: Highly durable.
7: Acceptable for daily wear but can be scratched or chipped. May need more care or specific settings.
6: Fragile. Most suited for earrings or necklaces.
<= 6: Requires gentle care. Should be stored or worn separate of other gemstones to prevent scratching by harder gems.
