We love this mounting, it is 14 karat gold, with a simple yet neat scroll design pendant & bail. We use this for a lot of stones but it lends itself especially well to the Lone Star Cut Blue Topaz. It's perfect to wear during the day & can make an easy transition to your night life as well, it's sure to help dress up any outfit from goin two-steppin with your man to rockin the rodeo!! Chain is not included, however feel free to browse our site & find one that will suit your Topaz wearing needs!!
