This stunning platinum wedding set features a 1.30 carat princess cut center diamond with a total diamond weight of 1.70 carats. Crafted in 950 platinum, the set showcases a princess cut center stone graded VS1 (Very Slightly Included) clarity and G (Near Colorless) color, delivering exceptional brilliance and near-perfect transparency to the naked eye. The set includes 16 diamonds in total, with round brilliant accent stones complementing the square-cut center.
All diamonds offered by Costco are natural and untreated. The ring is size 7 and is sizeable within one size (resizing service not provided by Costco). This item comes with a Jewelry Grading and Gemological Report certifying the authenticity of the stones, and includes a GIA (Gemological Institute of America) Gem Trade Laboratory Diamond Grading Report based on 10x magnification examination.
The set ships via air through UPS with insurance included, with an estimated delivery time of 2–3 business days. A signature is required upon delivery. Returns for items with a center diamond of 1.00 ct or larger require verification by a Costco Graduate Gemologist and may take up to five business days to process.
