This stunning platinum wedding ring features a cushion cut center diamond weighing 1.06 carats, set in a classic platinum mounting. The ring carries a total diamond weight of 1.59 carats, with the remaining 0.53 carats distributed among side or accent stones that beautifully complement the center stone.
The center diamond is graded VS1 (Very Slightly Included 1) for clarity, a grade that ensures no inclusions are visible to the naked eye and only minor inclusions are detectable under 10x magnification. The I color grade places the diamond in the near-colorless range on the GIA scale, offering an excellent balance of beauty and value. Platinum is used throughout for the setting, prized for its natural white luster, durability, and hypoallergenic properties โ it will not fade or change color over time.
Costco's jewelry is sourced to exacting standards and typically accompanied by a GIA grading report, offering confidence in the stated specifications. This piece represents exceptional value for a high-quality natural diamond in a timeless cushion cut style.
