It's amazing, and it looks good day or night.. It complements just about anything you want to wear. Titanium is a naturally iridescent metal that is applied to the back of the stone. The dominant colors are green and purple, with occasional flashes of yellow and red. A pretty danged large 22 carats, this is a seriously nice stone, clean and clear, with tons of bright, sparkly green/purple fire. Gives me goosebumps just to look at it., but then, I like Mystic Fire Topaz. Oh yeah -- it's pretty, too, especially with that flowing filigree running down the sides of the ring. ____________________________________________________________________ BTW, Since we make this from scratch after you order it, we have a lot of flexibility.
