2 Carat Lab-Grown Diamonds
A 2 carat diamond is a statement: about 8.1 mm across as a round brilliant, 10.2 × 7.2 mm as an oval, with a presence on the hand that no smaller size has. Lab-grown is what makes it attainable. Every stone on this page weighs 2.00–2.99 ct, is independently graded by IGI or GIA, and is shown with its live, VAT-inclusive price. Compare shapes below, see any stone true to size on a hand, and set it in a ring with our gemologists when you are ready.

How big is a 2 carat diamond?
A 2 ct round brilliant measures about 8.1 mm in diameter, roughly 1.6 mm more than a 1 ct. That may sound small, but face-up area grows faster than diameter: a 2 ct round shows about 55% more surface than a 1 ct, which is why the jump is so visible on the hand. Two carats is 0.4 g, or 200 points. As with every size, the shape and cut depth decide how large the stone looks, and elongated cuts spread the weight furthest: a 2 ct oval is over 10 mm long and a marquise over 13 mm. The table gives the typical face-up measurements of the 2.00–2.09 ct stones in our catalogue (median length × width, mm); heavier stones in the 2.00–2.99 ct range are larger again.
| Shape | Typical size of a 2 ct stone |
|---|---|
| Round | 8.1 mm |
| Oval | 10.2 × 7.2 mm |
| Pear | 11.2 × 7.1 mm |
| Marquise | 13.1 × 6.6 mm |
| Cushion (elongated) | 8.7 × 6.7 mm |
| Emerald | 8.7 × 6.0 mm |
| Radiant | 8.9 × 6.3 mm |
| Heart | 8.8 × 7.9 mm |
| Princess | 7.0 mm square |
| Asscher | 7.0 mm square |
On the hand, an 8.1 mm round covers about half the width of an average finger. Open any product and use the "see it true to size" tool to see it on your own hand before you decide; at this size the difference between a slim and a wide finger changes the look more than at any smaller size.
2 carat diamond rings
A stone this size needs a setting built for it. Prongs should be sturdier than on a 1 ct and a band of 2 mm or more keeps the proportions balanced; a six-prong or a double-prong solitaire holds the stone securely while showing its size; a bezel or half-bezel protects the girdle of a stone that will inevitably meet door frames and desks; a hidden halo under the stone adds sparkle from the side without adding width. Elongated shapes are especially rewarding at 2 ct: a 2 carat oval runs 10 mm along the finger, and an emerald cut of this size shows the long, mirror-like flashes the cut is known for. See round 2 carat diamonds for the classic. Every diamond is loose and ready to set: choose "Set this stone in a ring" on the product page or build the whole ring in the ring configurator, and our gemologists will advise on the setting.
How much does a 2 carat lab-grown diamond cost?
Prices on this page are live and include VAT, the grading report and insured delivery. Price per carat rises with weight, so a 2 ct stone costs considerably more than two 1 ct stones of the same grade, and within the 2.00–2.99 ct range the exact weight matters as much as the grade: a 2.5 ct stone is a different price bracket from a 2.0 ct. This is also the size where colour and clarity are most visible. An 8 mm stone shows body colour that a 5 mm stone hides, so F and above is the safer choice for white metals, and inclusions that would be invisible in a half-carat can be seen in a 2 ct, which makes VS1–VS2 the sensible floor and VVS worth considering. Our Reserve (F, VS) and Signature (D–E, VVS) tiers are built for this size. Lab-grown is what changes the equation: a lab-grown 2 ct typically costs 60–80% less than a mined stone of the same grade, so a size that was out of reach for most budgets is not. Read how the stones are grown and graded in our guide to lab-grown diamonds.
Choosing a 2 carat diamond
- Cut: Excellent, and check the proportions. A deep 2 ct stone hides weight below the girdle where it adds nothing to the look; compare the measurements on the product page, not just the carat.
- Clarity: VS1–VS2 minimum. Look at the certificate plot and our photograph; anything under the table is more visible at this size.
- Colour: F and above for platinum and white gold. Browse colourless VS stones and colourless VVS stones; near-colourless G–H still works well in yellow gold.
- Fluorescence. Check the fluorescence grade on the certificate; "none" or "faint" is the safe choice for a large, high-colour stone.

A 1.5 carat diamond is the usual alternative if 2 ct is more than the hand or the budget wants; a 1 carat diamond is about 6.5 mm; a 3 carat diamond is the next step up. Browse all sizes together in the diamond search, or see our engagement rings.
2 carat diamonds: frequently asked questions
How many mm is a 2 carat diamond?
About 8.1 mm in diameter as a round brilliant. A 2 ct oval measures roughly 10.2 × 7.2 mm, a pear 11.2 × 7.1 mm, an emerald cut 8.7 × 6.0 mm and a princess cut 7.0 mm square. Exact measurements are on each certificate and product page.
Is a 2 carat diamond too big for an engagement ring?
Not if the setting is right. A 2 ct stone is a statement, and on a slim finger it reads as one; a low profile, a bezel or a band of 2 mm or more keeps it wearable every day. Use the true-to-size tool on any stone to see it on a hand before you decide.
How much does a 2 carat lab-grown diamond cost?
It depends on the exact weight, colour, clarity and cut; every price on this page is live and includes VAT, the certificate and insured shipping. A lab-grown 2 ct typically costs 60–80% less than a mined 2 ct of the same grade.
Does the 2 carat collection include stones over 2.00 ct?
Yes. Stones here weigh between 2.00 and 2.99 ct; the exact weight is on every product and certificate. Stones of 3 ct and above are in the 3 carat collection.
Is a lab-grown 2 carat diamond real?
Yes. It has the same crystal structure, hardness and brilliance as a mined diamond; only its origin differs. Every stone here is graded by IGI or GIA, its report states that it is laboratory-grown, and it is inspected in Sweden before it ships.

Are lab-grown diamonds real diamonds?
