Tanzanite Center
The centerpiece of this ring is a 3.85 carat oval tanzanite with a lovely blue color. It’s cradled in a four-prong setting that rises up from a single point on the 14k white gold shank below. The prongs are large and smooth, providing a nice contrast with the rich color of the tanzanite while complementing its shape nicely.
Tanzanites were discovered relatively recently, with the first known stones dating only as far back as 1967. They are even more rare than diamonds, and they’re only found in one place on Earth. They generally come in between six and seven on the Mohs hardness scale, making them significantly softer than diamonds but still strong enough for use in fine custom jewelry.

Band Design
The band of this ring is smooth and flat, tapering gently as it nears the main setting. The top portion then angles up slightly on its way up to meet the side of the tanzanite, while a thinner piece continues across under the stone on the bottom. This is where the prongs of the main setting originate, and it acts as a bridge connecting the two sides of the shank. Custom Engagement Rings
Customization Options
This is a versatile and elegant design, offering many options for customization. If you like the overall outline of this piece but don’t think you want such a large center stone, we can scale it down until it’s more in line with what you’re after. We can also adapt the ring to accommodate a different shaped center such as a round or marquise, and we can help you select the perfect gemstone whether you’re interested in diamond, sapphire, or another alternative.
