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.
