This chunky Tiger Iron cabochon is really a doublet with a backing of Alabama Seam Agate. It was part of a class demonstration at a recent William Holland beginners' cabochons class. The cab has a light fracture across its midsection, so it's going to stay in my collection and used as a demo in the future.

40mm x 30.5mm x 10mm.   Weight: 102.80 carats.
