A classic platinum solitaire engagement ring featuring a 1.00 carat total weight round brilliant cut diamond with VS2 clarity and I color grading. The ring is set in a traditional four-prong platinum mounting, showcasing the diamond's fire and brilliance. Each diamond meets Costco's strict cut parameters for optimal light performance and is accompanied by GIA and IGI certification for independent quality verification.
The VS2 clarity grade ensures the diamond is eye-clean with no inclusions visible to the naked eye, while the I color grade offers a near-colorless appearance that represents excellent value. The platinum setting provides a durable, naturally white metal that will not tarnish or fade over time. Diamonds over 1 carat purchased from Costco include original certification and are eligible for Costco's return policy with a credit memo.
