There was only one word we could use to describe this color: Nuclear! I suppose we could have said 'radioactive,' but that might give the wrong idea. YAG has some mind-blowing colors but I'm in awe of this one. It's radiant in low light, and blinds in bright light! The real challenge is trying to capture its beauty on camera.


One thing that can really set YAG apart from others is its bright, bold, and beautiful colors! But it can come in every color of the rainbow as well as monochromatic black, grey, and colorless. YAG (Yttrium Aluminium Garnet) is a synthetic crystalline material of the garnet group. It began its story in the 1960's, being used for optics and laser technology. Due to it's hardness and brilliance, it soon found it's way into jewelry as a diamond simulant. With its hardness of 8.5, it makes an excellent choice for everyday rings.
