This stunning ring from Costco's fine jewelry collection features a 1.93 carat cushion-cut blue sapphire as its center stone, elegantly set in 14-karat white gold. The deep, velvety blue of the sapphire is complemented by 0.35 carats total weight of accent diamonds, adding brilliant sparkle to the classic design.
The cushion cut is a timeless shape with rounded corners and large facets that enhance the sapphire's natural color saturation and depth. Sapphires are among the hardest gemstones, rating 9 on the Mohs scale, making them an excellent choice for everyday wear. The 14-karat white gold setting provides a bright, modern backdrop that accentuates both the sapphire and the diamond accents.
Costco's fine jewelry meets rigorous quality standards and comes with independent gemological certification, ensuring authenticity and value. The ring is ideal as an engagement ring, anniversary gift, or a meaningful statement piece for any occasion.
