Copper Quartz Cabochon
Copper is a difficult material to cut and form. The heat alone gets so hot that it burns the fingers if not dunked into water every few seconds of grinding. These take longer to make. Also, wheels grip copper making it fly from the fingers.
Copper nodules were easier for the mining companies to harvest and transport. There are still massive slates of copper down in the mines that could not be removed due to their size. Even when trying to blast the copper, would only bend and warp the metal. 🌹
