This Costco solitaire engagement ring features a 0.72 carat round brilliant-cut diamond set in 18-karat white gold. The center stone carries VS2 (Very Slightly Included 2) clarity and E color โ a near-colorless to colorless rating that places it among the top tier of the GIA color grading scale, meaning the diamond appears bright and white to the naked eye with virtually no visible inclusions.
The classic solitaire setting places all attention on the diamond, making it a timeless choice for an engagement ring or a meaningful gift. 18-karat white gold provides a bright, lustrous setting that complements the diamond's brilliance and offers durability suitable for everyday wear. VS2 clarity ensures no inclusions are visible without magnification, and E color is the third-highest on the GIA scale, reflecting exceptional whiteness and brilliance.
Costco diamonds in this category are typically GIA-certified, providing independent verification of the stated carat weight, cut, clarity, and color grades.
