This Costco platinum wedding set features a round brilliant-cut center diamond weighing 1.03 carats, graded Internally Flawless (IF) for clarity and H for color, representing exceptional quality in the near-colorless range. The total combined diamond weight of the set is 1.71 carats, with the engagement ring and matching wedding band crafted in platinum for superior durability and a bright, enduring white finish.

The Internally Flawless clarity grade indicates no internal inclusions visible under 10x magnification, placing this diamond among the rarest and most prized available. The H color grade reflects a near-colorless diamond that faces up white, especially in a platinum setting, offering outstanding brilliance and value. The wedding set is designed so the engagement ring and wedding band nest together seamlessly for a cohesive bridal look.

All Costco diamond jewelry is accompanied by a GIA (Gemological Institute of America) Diamond Grading Report, certifying the diamond's quality characteristics. Costco's platinum jewelry uses 950 platinum, offering greater purity and weight than white gold alternatives.
