This stunning fine jewelry ring features a 2.93 carat oval cut tanzanite centerstone set in 18-karat white gold with rhodium plating. The vivid violet-blue tanzanite is complemented by 1.29 carats total weight of round brilliant natural diamonds surrounding and accenting the center gem.

Tanzanite is one of the world's rarest gemstones, found exclusively near Mount Kilimanjaro in Tanzania. Its rich trichroic color shifts between violet, blue, and burgundy depending on viewing angle and lighting. As is standard in the industry, the tanzanite in this ring has been heat-enhanced to bring out its signature blue-violet hue. All diamonds are natural and untreated.

The ring is crafted in 18KT white gold with a rhodium plate finish for lasting brilliance and durability. Ring size 7, sizeable within one size (sizing service not provided by Costco). Comes with a gemological grading report. Air shipping via UPS insured is included; signature required upon delivery.
