This elegant platinum engagement ring features a round brilliant-cut center diamond weighing 1.20 carats, flanked by two baguette-cut side diamonds, for a total combined carat weight of 1.51 CTW. The center stone is graded VVS2 (Very Very Slightly Included 2) for exceptional clarity, with an "I" color grade indicating near-colorless appearance to the naked eye.
The ring is crafted in platinum, a premium precious metal prized for its durability, natural white luster, and hypoallergenic properties. Platinum is denser and more durable than white gold, making it an ideal choice for securing high-value diamonds. The classic three-stone design with baguette side stones frames the center round brilliant cut, enhancing its brilliance and adding visual width to the band.
Costco's diamond jewelry is certified by the Gemological Institute of America (GIA) or equivalent grading laboratories, ensuring the stated quality grades are independently verified. The VVS2 clarity grade means inclusions are minute and extremely difficult to detect even under 10x magnification, placing this stone in the near-flawless category.
