Question: What is the origin of Moissanite?
Answer: Particles of the material were originally discovered by Dr. Henri Moissan during his work at an ancient meteorite crash in the Diablo Canyon in Arizona in 1893. This meteorite crash happened approximately 50,000 thousand years ago. This amazing brilliant and diamond-like material discovered by Dr. Moissan was from the fragments of the meteorite. It was named "Moissanite" in honour of Dr. Moissan in 1905.

Question: What is the typical colour of Moissanite?
Answer: Moissanites are "H to J" in colour which is similar to many diamonds which also fall into this range of colour.

Question:How much whiter are FOREVER BRILLIANT™ and FOREVER ONE™ Moissanites?

Question: If I don't order a FOREVER ONE™ Moissanite, will my FOREVER BRILLIANT™ or CLASSIC Moissanite look nice?
Answer: All Moissanites have more lustre, fire and brilliance than any other gemstone on earth. If you are considering Moissanite for an engagement ring, we recommend FOREVER BRILLIANT™ or FOREVER ONE™ Moissanite for your center stone or large side stones because it has the whitest colour. For smaller size stones, you can still use CLASSIC Moissanites.
