Round Brilliant Diamond Ring Guide: Cut, Carat and Price
Buying guide
A round brilliant diamond has 57 or 58 facets arranged to return as much light as possible, so it sparkles more than any other shape. It is the classic engagement ring stone because it sparkles the most and suits almost any setting. To choose one, decide on a natural or lab-grown diamond, then the carat, then the gold colour, and check the cut grade on the certificate. The Lana Al Kamal Classic Round Diamond Ring is an 18K gold solitaire with one round brilliant centre diamond and costs AED 6,000 to AED 105,000 (November 2026), depending on the diamond you choose.

Why choose a round diamond?
Choose a round if sparkle matters most to you, or if you want a ring that will look as right in thirty years as it does today. Its symmetry hides small inclusions and a slight tint better than most shapes. In many shops a round costs more per carat than other shapes; at Lana Al Kamal the Classic Round costs the same as our Classic Oval, Emerald, Cushion, Heart and Marquise, so you can choose the shape on looks alone.
What to check on a round diamond
- Cut grade: for round diamonds, GIA and IGI give a cut grade from Excellent (or Ideal) down to Poor. It decides how much the stone sparkles, so it is the first grade to read.
- Colour and clarity: because a round sparkles so much, it hides a slight tint and small inclusions well, so you can often choose a step lower on colour or clarity without seeing a difference.
- Carat and spread: two diamonds of the same carat can look different in size if one is cut too deep. The certificate lists the measurements in millimetres.
- The certificate: the centre diamond comes with an IGI or GIA certificate, in print and digital form, which states the carat, colour, clarity and cut. Read about these grades on GIA's diamond quality factors.
What to buyClassic Round Diamond Ring, from AED 6,000Natural or lab-grown round?
Both are real diamonds with the same hardness and look. A natural diamond formed in the earth; a lab-grown CVD diamond was grown in a laboratory. At 1 ct, a lab-grown round costs AED 6,000 and a natural one AED 45,000. Choose natural if rarity matters most, or lab-grown for a larger stone on the same budget. Our natural or lab-grown checklist goes into more detail.
Round or another shape?
For almost the same sparkle in a longer shape that looks larger on the finger, look at the Classic Oval Diamond Ring and our oval diamond ring guide. For a soft square, read the cushion cut diamond ring guide. Our diamond shapes compared guide shows all seven shapes side by side.
