This stunning platinum wedding set features a round brilliant cut center diamond weighing 1.20 carats with VS1 (Very Slightly Included) clarity and G (Near Colorless) color, for a total combined diamond weight of 1.50 carats. The setting is crafted in 950 platinum, one of the most durable and prestigious precious metals, providing a brilliant white finish that will not fade or tarnish over time.
The set includes a solitaire-style engagement ring showcasing the round brilliant center stone, paired with a matching diamond-accented band. All diamonds offered by Costco are natural and untreated. A Jewelry Grading / Gemological Report is included, certifying the diamond's authenticity and characteristics. For center diamonds of 1.00 ct or larger, a GIA (Gemological Institute of America) Diamond Grading Report is also included, providing an independent assessment of the diamond's cut, color, clarity, and carat weight based on 10x magnification. The diamond is the traditional April birthstone and a timeless symbol of love and commitment.
Shipping and handling are included, and the set arrives via insured air shipping with signature required. The ring is sizeable within one size; Costco does not provide resizing services directly. When returning, Costco warehouses may require additional time (up to five business days) to verify diamonds of this caliber with a Graduate Gemologist before issuing a refund.
