5mm Black Round Cabochon Opal with Yellow Fire

5mm black round cabochon opals with yellow fire. These cabochons are domed on one side and flat on the other.

All opals sold at Lampwork Supply are lab created using the Gilson Opal technique and are compatible with borosilicate glass.

To minimize handling and offer the best price these opals come in bags of five. You must order in quantities that are divisible by 5 or you will get an error.
