💫 Copper-water lore and care
The name Chrysocolla comes from Greek words meaning “gold” and “glue”, recalling copper-bearing substances once used by metalworkers. Translucent blue-green Chalcedony coloured by copper is widely known as Gem Silica and is much harder than ordinary porous Chrysocolla.
Hardness varies from roughly 2–4 in soft, porous material to about 6.5–7 in silica-rich pieces. Keep specimens dry, separate them from harder stones and clean only with a soft cloth or brush. Avoid soaking, acids, salt, steam and ultrasonic cleaning. As a copper-bearing material, it should not be ingested or used to prepare crystal water.
