How much is a 2 carat lab-grown diamond?
A 2 carat lab-grown diamond typically costs roughly $900 to $2,500 for the loose stone as a market range in early 2026, with a finished ring often landing around $1,500 to $4,500 once the setting is added. The price swings within that range based on cut, color, clarity, and shape. A 2 carat lab-grown diamond costs a fraction of what a 2 carat mined diamond does at the same grade. This guide covers what a 2 carat lab-grown diamond costs loose and as a ring, what moves the price, and how to get the best-looking stone for your budget. These are general market ranges, not Candor prices, and lab-grown pricing shifts over time, so check current stones before you buy.
What a 2 carat lab-grown diamond costs
As a rough market guide in early 2026, a loose, certified, near-colorless, eye-clean 2 carat lab-grown diamond with a good to excellent cut commonly runs about $900 to $2,500. Set into a ring, expect roughly $1,500 to $4,500 depending on the metal, the setting style, and any side stones.
| What you are buying | Typical market range (early 2026) |
|---|---|
| Loose 2 carat stone | Roughly $900 to $2,500 |
| 2 carat solitaire ring | Roughly $1,500 to $3,500 |
| 2 carat halo or pave ring | Roughly $2,500 to $4,500 |
These are ranges, not quotes. Two stones at 2 carats can price very differently based on their grades, and lab-grown prices have been falling.
What moves the price of a 2 carat stone
Carat is fixed here at 2, so the spread comes from the other three of the 4Cs, plus shape:
- Cut sets the sparkle and can make a 2 carat stone look larger and brighter. Keep this grade high.
- Color in the G to J near-colorless range usually looks white once set and costs less than D to F.
- Clarity at an eye-clean VS1 or VS2 shows no inclusions to the naked eye, the practical target.
- Shape changes the math. Round costs the most per carat. Oval, emerald, and pear often cost less and can look larger for the weight.
A near-colorless G or H, eye-clean VS2, well-cut 2 carat stone gives most of the look of a top-grade stone for less money. That is where the value sits.
How big does a 2 carat diamond look?
A 2 carat round diamond measures roughly 8 to 8.2 millimeters across, a clear step up in presence from a 1 carat stone at around 6.4 millimeters. Elongated shapes such as oval and marquise look even larger for the same weight, because they spread more across the finger. If face-up size is your goal, an elongated shape at 2 carats reads bigger than a round of the same weight. A halo of small accent diamonds around the center adds to the effect.
Is a 2 carat lab-grown diamond worth it?
A 2 carat lab-grown diamond gives you real, certified diamond at a size that would cost several times more if mined, which is why it is one of the most popular choices for engagement rings. You get genuine diamond hardness and sparkle, graded on the same 4Cs by IGI or GIA, at a price that leaves room for a better cut or a nicer setting. The trade-off is the weak resale value shared by all lab-grown diamonds, so choose it for the look and value now, not to resell.
Quick math on the size-for-budget point: a budget that might buy a 1 carat mined diamond often covers a 2 carat lab-grown diamond of similar cut, color, and clarity. That is the whole appeal, more visible stone for the same spend. And a bigger lab-grown stone is not a lower-quality one; quality is set by the grades on the certificate, not the size or the lab origin.
The bottom line
A 2 carat lab-grown diamond is a genuine, certified diamond with real presence on the hand, at roughly a fraction of the mined price for the same size and grade. Prioritize cut and eye-clean clarity, accept a near-colorless color you cannot fault by eye, and let the setting do the rest. At Candor Diamonds, every 2 carat lab-grown diamond is IGI or GIA certified, with the report available so you can match the grades to the price before you buy. Each stone comes with a lifetime warranty, free insured shipping, and 30-day returns, so a statement-size diamond stays an easy, confident purchase.

Is a 2 carat lab-grown diamond cheaper than a 2 carat mined diamond?
Yes, by a wide margin. A 2 carat lab-grown diamond costs a fraction of a 2 carat mined diamond at the same grade, because it can be grown on demand rather than mined. The two are the same material and graded the same way.
How many millimeters is a 2 carat diamond?
A 2 carat round diamond is roughly 8 to 8.2 millimeters across. Elongated shapes such as oval look larger for the same weight because they spread more across the finger.
What color and clarity should I choose for a 2 carat lab-grown diamond?
A near-colorless G or H color with an eye-clean VS1 or VS2 clarity looks white and clean to the naked eye and costs less than top D to F, IF grades. Keep cut high for the best sparkle.
Do 2 carat lab-grown diamonds hold their value?
No. Lab-grown diamonds hold little resale value today, at 2 carats or any size. Choose one for its beauty and the value it buys now, not as an investment.
