How to Identify Aquamarine
Aquamarine is blue to blue-green beryl: six-sided prismatic crystals, often with flat terminations, glassy luster, hardness 7.5–8 — it scratches quartz. Color is typically pale and even, unlike the zoned purple of amethyst or the bottle-green of common beryl. Crystals frequently sit in or beside massive white quartz and feldspar.
