* Prices shown are for Costco members only.
This elegant ring features a 10x8mm oval tanzanite centerstone set in rhodium-plated 14kt white gold, accented by round brilliant-cut diamonds totaling 0.18 carats. The diamonds are graded VS2 (Very Slightly Included) for clarity and I (Near Colorless) for color, ensuring a bright, clean appearance.
Tanzanite is prized for its striking violet-blue hue, which shifts between blue and purple depending on the lighting. All Costco diamonds are natural and untreated. As with most colored gemstones, the tanzanite has been enhanced during the production process, which is standard practice in the industry.
The ring is size 7 and may be sized within one size by an independent jeweler. It ships via insured UPS air delivery with signature required.
