Here at Moriarty's Gem Art, we do many different Tanzanite designs. Over the past couple years, Tanzanite Engagement Rings have been becoming more and more popular. Overall, gemstone engagement rings and wedding rings have been the choice to use over Diamonds in recent years and it continues to grow. While our selection of Tanzanite wedding rings is small, you can choose from any of our Tanzanite gemstones and we would be happy to custom design an engagement ring to fit it. No matter if you are looking for white gold, yellow gold, rose gold or platinum, we can design a Tanzanite wedding ring or band to fit your style!
