Opal Drop EarringsHandmade in New Zealand, these stunning opal earrings are encased in clear glass and hung on sterling silver findings. They are handcrafted on the blowtorch from synthetic Gilson Opals, which have the same chemical and physical properties as natural opals but are more temperature stable, so I can use them in glassblowing! The opals shine with colour and are show stoppers when encased.
