A clear stone, similar to diamond, but man-made.  It's probably the most expensive diamond simulant, and in our opinion is best enjoyed for its unique qualities.
While it's not as hard as diamond (nothing is), it's tougher, and less brittle, so it should last for many years.  It also has more fire than a genuine diamond.

Distinguishing it from a diamond

Most people with an interest in precious stones will be able to tell the 2 stones apart.  Here are some pointers:

Caring for Moissanite

The stones are tough, and should stand up to all normal cleaning methods, and to normal wear and tear.

Appreciate Moissanite for its Beauty

While it is often sold for its similarity to diamond, in our judgement it's best enjoyed for its own unique qualities.  We consider CZ to be closer to diamond in appearance.
Moissanite will sparkle more, and is very tough, lacking the brittle nature of many precious gemstones.
For a man-made stone, it is expensive, and there may be problems re-selling it.  Our customers prefer natural gems, so we would be reluctant to pay a reasonable percentage of the new price for moissanite.  However they may be a specialised market for jewellery including these stones.

Unmounted moissanite Above, a typical moissanite.  Note the amount of reflection and fire, more than you would see in a diamond.  The white spots are dust on the surface;  sorry, but I wan't as careful as usual in cleaning this stone!
Below:  Detail, showing the rear facets through the gem.  Note how the facet edges look doubled.  This is conclusive proof the stone is not a diamond.  Slight marks caused by grease on the stone.

To identify moissanite, look through the stone and note how the facet edges appear doubled
