These elegant stud earrings are crafted in 14-karat white gold and feature a stunning combination of diamonds and genuine tanzanite gemstones. The earrings have a total diamond carat weight of 0.74 CTW, with stones graded at VS2 clarity and I color, indicating very slight inclusions visible only under magnification and a near-colorless appearance to the naked eye.

Tanzanite, found exclusively in Tanzania near Mount Kilimanjaro, is prized for its rich violet-blue hue and is significantly rarer than diamonds. The deep blue-violet tanzanite center stones are complemented by the brilliant white diamonds set in polished 14kt white gold, making these earrings a versatile choice for both everyday wear and special occasions. The style code E23259TZ identifies this as a specific design in Costco's fine jewelry collection, featuring a secure stud-style post backing.
