These rock crystal chandelier crystals were originally used in the earliest days of indoor lighting when hanging fixtures were typically lighted with candles (i.e. before kerosene or whale oil)
This rock crystal is actually a semi-precious, colorless stone that is quarried, then hand cut and polished
These are mainly intended for use on high-end fixtures and sconces
