This Silver Lace Agate oval is actually a doublet. It was part of a demo in the most recent class I taught at William Holland. The cabochon is covered with a dome of synthetic Quartz. There are some small bubbles between the layers, so I'm not going to sell it. But I kinda like it anyway!

Dimensions: 40mm x 31.5mm x 11mm.  Weight: 118.00 carats.

This cabochon is in my personal collection; it is not available for sale.
