In-store pricing snapshot

* Prices shown are for Costco members only.
This classic solitaire ring features a single round brilliant cut natural diamond weighing 0.70 carats, set in a solid platinum four-prong mounting. The diamond carries VS2 clarity (Very Slightly Included), meaning any inclusions are virtually invisible to the naked eye, and I color grading (Near Colorless), providing exceptional brilliance and sparkle at outstanding value compared to higher color grades.
Platinum is hypoallergenic, naturally white, and significantly more durable than gold, making it an ideal metal for an engagement or special occasion ring worn daily. Unlike white gold, platinum does not fade or require rhodium replating over time. The ring is offered in size 7 and can be sized to any size by a local jeweler (Costco does not provide resizing services). This ring is also available in 14kt yellow gold.
All diamonds offered by Costco are 100% natural and untreated, certified to the highest standards. The ring ships air freight via insured UPS with signature required, with an estimated delivery of 2-3 business days. It is backed by Costco's 100% satisfaction guarantee.
