Not related to semiconductors but I've recently bought a ring with a lab made silicon carbide moissanite crystal.

They're incredibly beautiful and I think a good alternative to diamonds:

I bought one for my wife's wedding ring as well. The local jeweller (who made the rings) tested it with his diamond tester device -- and the led light said 'diamond'. He was a bit surprised :-)

Wikipedia agrees... :)

> As some of its properties are quite similar to diamond, moissanite can be used for scams. Testing equipment based on measuring thermal conductivity in particular may give deceiving results.
