Item Name:

Cut Opal Lightning Bolt 12mm - Black with Green Fire

SKU:

COBGF-LIGHTNING-12MM

Description:

This is a hand-crafted, pre-shaped cut opal made in a lightning bolt profile. It features a black opal base with green fire that flashes and shifts as the piece moves under light. Cut opals like this are used in lampworking when you want a clean, repeatable shape that gives strong visual impact without needing to hand-cut stone yourself. The lightning bolt shape is especially useful for bold graphic designs, character work, and high-contrast inlays where you want the opal to read clearly even from a distance.

How it is used:

This cut opal is typically used as an inlay in borosilicate lampworked pieces such as pendants, marbles, beads, and small sculpture. The opal is seated into a prepared pocket in the hot glass surface, then the surrounding glass is carefully heated and worked to lock it in place without overheating the stone. Once set, the piece should be brought through a controlled annealing cycle to reduce stress and help protect the opal from cracking due to thermal shock.
