This magnificent sample of elbaite with albite and quartz is from the Tourmaline Queen mine, San Diego County, California. It is about 25 cm wide. As the elbaite crystals grew, the growth solution changed from manganese-rich to iron-rich, creating a blue top on each "candle" (This sample is nicknamed "Candelabra").
