2 Carat Lab Grown Diamond: Price, Size & Grades

Quick answer: A 2 carat lab grown diamond is one of the best values in fine jewelry today. In the US, a certified loose 2 carat stone typically costs from around $1,000 to $3,500, depending on its cut, color, clarity, shape and the retailer. A well-cut 2 carat round measures about 8.1 mm across, which looks bold and generous on most hands.

Because lab grown prices rise gently with size, many buyers who once planned on 1 carat now choose 2 carats for a similar budget. Here is what to know before you buy one.

How Big Is a 2 Carat Diamond?

Carat is weight, not size, so the visible size depends on shape and cut. These are typical face-up measurements for well-cut 2 carat diamonds:

Shape	Approximate size	How it looks
Round	about 8.1 mm	Classic, maximum sparkle
Oval	about 10 x 7 mm	Looks larger, lengthens the finger
Cushion	about 7.5 x 7.5 mm	Soft square, romantic look
Emerald	about 9 x 6.5 mm	Elegant step cut, shows clarity more
Pear	about 11 x 7 mm	Long, graceful and eye-catching

Measurements vary with each stone's proportions. Always check the millimeter size on the IGI report. You can also compare sizes on our diamond size chart.

What Grades to Look For at 2 Carats

A larger diamond shows more of its color and clarity, so choose grades a little more carefully than you would at 1 carat.

Cut

Choose Excellent or Ideal cut with Excellent polish and symmetry. At this size, a great cut is what makes the stone look bright instead of glassy.

Color

F to G is a strong sweet spot for a 2 carat stone in white gold. If you prefer yellow or rose gold, G to H still looks bright and saves money.

Clarity

VS1 is a safe choice for eye-clean appearance at 2 carats. In step cuts like emerald and Asscher, which show inclusions more easily, consider VS1 or better.

2 Carat Lab Grown Diamond Price: What Moves It

Shape: rounds usually cost the most; ovals, pears and cushions often cost less.
Color and clarity: D color and VVS clarity sit at the top of the range.
Cut: the best-cut stones cost a bit more and are worth it.
Retailer: prices for similar grades can vary a lot from store to store, so compare certificates, not just totals.

Is a 2 Carat Diamond Too Big for Everyday Wear?

For most people, no. A 2 carat stone in a low-profile setting, such as a bezel or a low basket, sits closer to the finger and catches less on sweaters and gloves. Six prongs hold a round stone securely, and a hidden halo adds sparkle without extra height. If you work with your hands, a bezel setting gives the most protection.

2 Carat vs 1.5 Carat: Which Should You Choose?

A 2 carat round is about 8.1 mm, while a 1.5 carat round is about 7.4 mm. The difference is visible side by side, but a 1.5 carat stone in a halo setting can look close to 2 carats. If you want the most presence for your budget, a 2 carat oval or pear gives a big look without top-tier color grades.
