A stunning 14kt white gold ring featuring a vibrant tanzanite center stone accented by 0.48 carats total weight of round brilliant diamonds. Crafted in rhodium-plated 14kt white gold, the setting enhances the ring's bright white luster while providing additional durability and resistance to tarnishing.

Tanzanite is one of the world's rarest gemstones, found exclusively near Mount Kilimanjaro in Tanzania. It is prized for its remarkable trichroic quality, displaying shifting hues of blue-violet to violet-blue depending on lighting and viewing angle. The surrounding diamonds are graded VS2 (Very Slightly Included) clarity and I color (Near Colorless), delivering exceptional brilliance and sparkle. All Costco diamonds are natural and untreated. The tanzanite has been enhanced in the production process, which is standard practice for colored gemstones in the jewelry industry.

The ring is available in size 7 and is sizeable within one size. Costco does not provide resizing services directly. Tanzanite is December's birthstone, making this piece a meaningful gift. Ships air insured via UPS with signature required, and is backed by Costco's 100% satisfaction guarantee with returns accepted at any Costco warehouse worldwide.
