Explore Round Cut Diamonds at Ouros Jewels

Round cut diamonds are recognized by their circular outline and brilliant-style faceting. Ouros Jewels offers loose round lab grown diamonds across different carat weights, color grades, clarity grades, and cutting styles, from classic round brilliant diamonds to selected specialty round cuts.

Shoppers comparing other diamond shapes can explore the complete lab grown diamonds collection.

What Makes a Round Brilliant Diamond Different?

A round brilliant diamond uses a symmetrical facet arrangement designed to direct light through the stone and back through the top. A standard round brilliant typically has 57 facets, or 58 when the culet is faceted.

Because of this precise geometry, cut quality has a strong influence on brightness, fire, and scintillation. Two round diamonds with the same carat weight and clarity can therefore appear noticeably different when their proportions and cutting quality differ.

How to Choose a Round Cut Diamond

When comparing round diamonds, consider the combination of cut, color, clarity, proportions, and carat weight rather than judging the stone by size alone.

• Cut affects how effectively the diamond handles light.
• Color indicates how colorless or tinted the diamond appears.
• Clarity describes inclusions and surface characteristics.
• Symmetry considers how accurately the facets are aligned.
• Polish describes the finish of the facet surfaces.
• Table and depth help show how the diamond's proportions are balanced.
• Carat weight measures the diamond's weight, while visible size also depends on its dimensions and proportions.

The best combination depends on the finished jewelry, visual preferences, and budget.

Certified Round Lab Grown Diamonds

Selected round lab grown diamonds are available with independent grading reports depending on the individual stone and its specifications.

A grading report can document characteristics such as carat weight, color, clarity, measurements, proportions, polish, and symmetry. Shoppers specifically looking for graded stones can explore certified loose diamonds.

Check the individual diamond listing to confirm which grading report, if any, is included with the stone.
