The image below just does not give justice to this great diamond. I've taken a video with my cellphone (of which the quality is really bad) but it will at least show you the stone in more detail. Access it here.
As the title states, this is a black moissanite. Please read more about that here.
From WikiPedia:
Moissanite was introduced to the jewelry market in 1998.[15] It is regarded as an excellent fine jewel, with some optical properties exceeding those of diamond. Its ethical production makes it a popular alternative to diamonds. On the Mohs scale it is a 9.5, with a diamond being a 10.[3] Moissanite is stronger than sapphire or ruby. In many developed countries, the use of moissanite in jewelry has been patented; these patents expire in 2015 for the US, and 2016 in other countries.[16][17][18] Moissanite gemstones are sometimes marketed under the trademark "Berzelian," a reference to the work of Berzelius on SiC.
Because of its hardness, it can be used in high-pressure experiments, as a replacement for diamond (see diamond anvil cell).[5] Since large diamonds are usually too expensive to be used as anvils, synthetic moissanite is more often used in large-volume experiments. Synthetic moissanite is also interesting for electronic and thermal applications because its thermal conductivity is similar to that of diamonds.[13] High power SiC electronic devices are expected to play an enabling and vital role in the design of protection circuits used for motors, actuators, and energy storage or pulse power systems.[19]
