About 2 Carat Lab Grown Diamonds
2 Carat Lab Grown Diamonds – Exceptional Brilliance and Modern Luxury
A 2 carat lab grown diamond offers impressive presence, refined elegance and extraordinary brilliance, making it a preferred choice for UK customers who want a standout centre stone. With double the carat weight of a classic 1 carat diamond, the 2 carat grade provides a bold yet balanced visual impact, ideal for engagement rings, high-end jewellery settings and investment-quality stones.
Created using advanced CVD and HPHT technology, 2 carat lab grown diamonds share the same carbon composition, hardness and optical properties as mined diamonds. The only difference is their origin — grown responsibly above ground, without the environmental impact of mining. At Variation, every diamond is IGI-certified and hand-selected for brilliance, symmetry and clarity to ensure exceptional quality.
What Is a 2 Carat Lab Grown Diamond?
A 2 carat diamond weighs 0.4 grams and delivers a striking visual presence, making it one of the most desirable options for customers seeking luxury with proportion and symmetry. Lab grown diamonds replicate the natural crystallisation process, resulting in genuine diamonds that match mined stones in brilliance, fire and structure.

Frequently Asked Questions
Is a 2 carat lab grown diamond considered big? +
Yes — a 2 carat diamond is considered a premium, visually striking size. Whether round,
oval, emerald, or radiant, a 2 carat diamond offers significant presence on the hand
and is larger than what most people wear daily, making it a popular choice for luxury
engagement rings and statement jewellery.
How big does a 2 carat lab grown diamond look compared to a 1 carat diamond? +
A 2 carat diamond looks noticeably larger — not just double the weight, but significantly
bigger in surface area. Depending on the shape, it can appear up to 50–70% larger
when viewed from above, especially in shapes like oval, pear, and radiant.
Are 2 carat lab grown diamonds more affordable than mined diamonds? +
Yes. Lab grown diamonds offer exceptional value — a 2 carat lab grown diamond can cost
up to 70% less than a mined diamond of the same cut, color, and clarity, making big
sizes more accessible without compromising on beauty or quality.
Do 2 carat lab grown diamonds sparkle as much as natural diamonds of the same size? +
Yes. Lab grown diamonds have identical chemical, optical, and physical properties to natural diamonds.
A well-cut 2 carat lab grown diamond will display the same brilliance, fire, and scintillation as a
natural diamond of equal quality.
What clarity and color grades are recommended for a 2 carat diamond? +
Because of the larger size, inclusions and color are more visible in 2 carat diamonds.
Most buyers prefer D–F color and VVS1–VS1 clarity for a clean, high-quality appearance.
However, excellent cut is the most important factor for maximum sparkle.
Do 2 carat lab grown diamonds come with IGI or GIA certification? +
Yes. 2 carat lab grown diamonds are commonly certified by IGI or GIA, with a full grading report
detailing the 4Cs, polish, symmetry, fluorescence, and growth method (CVD or HPHT).
Is a 2 carat diamond suitable for everyday wear in an engagement ring? +
Absolutely. A 2 carat diamond is durable for daily use, as both lab grown and natural diamonds
have a Mohs hardness of 10. Pairing it with a secure setting — like a 4 or 6 prong,
halo, or bezel — ensures long-term safety and comfort.
Which shapes look largest in the 2 carat range? +
Ovals, pears, marquise, and emerald cuts often appear larger than their 2 carat weight
due to elongated proportions and large face-up area. Round diamonds look slightly smaller
but provide the brightest overall sparkle.
Is a 2 carat lab grown diamond a good choice for pendants or earrings too? +
Yes. 2 carat diamonds (or 1 carat each for earrings) make luxurious solitaires with excellent
visual impact. They are ideal for tennis pendants, classic studs, and high-end fine jewellery.
Are there many options in 2 carat lab grown diamonds? +
Yes — you can choose from round, oval, cushion, emerald, radiant, pear, marquise, princess,
heart, and many fancy shapes, along with a wide selection of color, clarity, and cut qualities
within the 2 carat range.
