There are lots of other, more budget-friendly engagement rings at Costco, like this Round Brilliant & Baguette 1.68 ctw VS2 Clarity, I Color Diamond Platinum Ring for $4,499.99. “This ring has a substantial weight to it and doesn’t feel light or flimsy, which immediately makes it feel high quality. The design is beautiful and well balanced—elegant without being too flashy. One of the best things about it is the sparkle; it catches the light incredibly well and still shines even from a distance. I ordered a size 5, which is my usual size, and it fit perfectly, true to size. Overall, it feels solid, looks stunning, and is a great-looking piece,” writes a shopper.

There are also lots of wedding band options in gold and platinum, including the 5mm Comfort Fit Wedding Band, starting at $699.99. “The journey to find the one ring is over! I searched Middle Earth for months trying to find a platinum wedding band at a reasonable price, and couldn’t believe it when I found this ring on the Costco app. It’s is a beautiful, solid ring and the price is incredible. I’ve had my ring for a few weeks and it’s so comfortable that sometimes it feels like I’m not wearing it. The polish is very shiny, but like all platinum rings it does develop a patina somewhat easily so keep that in mind when wearing it. I might buy a few more of these rings because I love it that much, I highly recommend,” a shopper wrote.
