A tentative identification of this classroom demo oval. The entire surface appears to be the same hardness, unlike the few examples of Youngite I've seen. Regardless, a pretty cab; the healed fractures at lower left are less evident in person.

40mm x 30mm x 5mm.   Weight: 44.25 carats.

Every one of my cabochons is custom cut to take the best advantage of the particular slab from which it is fashioned. Colors may vary somewhat from what is pictured due to differences in computer monitors.
