I completed this custom Platinum ring a couple weeks ago.
It has a green Fair Trade Montana sapphire set in a prong-bezel hybrid setting and 2 recycled Harmony diamonds are set flush into the sides of the ring. Erin, the new lucky owner of this ring wrote me after receiving it" Just wanted to tell you that I love, love, LOVE it!". Mission accomplished :-)
Here a couple more pictures:
A similar ring design with other available Montana sapphires but without the side diamonds is listed on my web site. If you want to add side stone to make your own custom ring please contact me for quotes.
