It is a diligent ring. It is not the size I expected. The three diamonds in the mist of it all is a little pit larger than I thought.

Had a shipping hiccup but wow. This black diamond is worth way more than it’s being sold for. I got the 2ct. And yes it’s set in silver but the stone itself is worth far more than what they are selling it for so you can easily have it reset into any setting should you choose. By far my favorite Groupon to date!

The diamonds are white and cloudy, but it’s a very sweet ring. You get what you pay for and I am happy with my purchase.

Bought this to replace my old wedding band that was lost. Wish it was 14k gold to match my engagement ring but honestly you can’t even tell the difference. EXCELLENT purchase for the price!!

Shop Diamond Rings Every Day on Groupon

Buying a diamond ring is a momentous decision (even if it’s not an engagement ring), and a little research before you shop can eliminate a lot of stress. Whether you’re looking for a giant 5-carat diamond ring or a half-carat diamond in white gold, our diamond buying guide can help you pick out a great stone with its comprehensive look at cut, color, clarity, and weight. The same general principles apply whether you’re looking for a pavé ring—which uses closely-set tiny gemstones to create the impression of a solid diamond surface—or a dazzling blue diamond ring.

Check the Cut...

A diamond’s cut—not to be confused with its shape—can range from Ideal to Poor, and measures a diamond’s reflective quality or brilliance. When a diamond is cut with the correct proportions, light is returned out of the diamond’s top. If the cut is too shallow or too deep, light escapes out the bottom or flows through the sides.

...And the Clarity...

Clarity is a measure of the tiny imperfections, birthmarks, or inclusions that appear on most diamonds. Grades range from flawless FL (no inclusions) to I3 (inclusions visible under 10x magnification).

...And Make Sure It Fits

Before you make a final decision, ensure you’ve got an accurate finger measurement by using Groupon’s ring sizing guide to find the right length and size. A little measuring with a piece of string and a ruler, or with a printable diagram, can help you avoid the need for resizing.
