Engagement Ring 2ct Solitaire Round Shape Lab-Grown Diamond
The Karat Store · Handcrafted in Solid Gold
Made to order in solid 10ct, 14ct or 18ct gold, the Engagement Ring 2ct Solitaire Round Shape Lab-Grown Diamond showcases a 2ct round brilliant-cut lab-grown diamond. The diamonds are graded F colour, VS2 clarity, for a bright, clean sparkle. The round brilliant cut returns more light than any other shape, so it gives the most sparkle from every angle. The solitaire setting keeps all the attention on the centre stone. It is a timeless choice that never dates.
It is a proposal ring made to be worn every day for a lifetime, and it pairs beautifully with a matching wedding ring. Available in yellow, white or rose gold and UK ring sizes D to Z+1.
Enhancing the solitaire design are 24 round lab-grown diamonds, adding a total carat weight of 0.14. These delicate side stones provide a subtle shimmer along the band, elevating the ring’s elegance without detracting from the central diamond’s grandeur. Crafted in solid gold, the band is sleek and refined, measuring 1.8 mm in width and 1.4 mm in height. The absence of rhodium plating highlights the natural warmth and richness of the gold, complementing the diamonds beautifully.
Yes. A lab-grown diamond has the same chemical, physical and optical properties as a mined diamond. It is simply grown in a controlled environment rather than mined. It will pass a diamond tester and is just as hard (10 on the Mohs scale).

18ct gold (75% pure gold) has the richest colour and a luxurious weight. 14ct gold (58.5% pure gold) is the most popular balance of colour, durability and value. 10ct gold (41.7% pure gold) is the hardest-wearing and most affordable option. Every option is solid gold all the way through, not plated.
White gold is finished with a bright rhodium plating. Over time, usually every 12 to 18 months with daily wear, it can soften to a warmer tone. Any jeweller can re-plate it quickly to restore the bright white finish.
This ring is made to order in UK sizes D to Z+1, so it is crafted to your size from the start. It can usually be resized later by a jeweller by one or two sizes. If you are unsure of your size, a local jeweller can measure you for free, or see our ring size guide.
Most straight wedding rings sit neatly beside it. If the setting sits low on your finger, a curved or contoured band gives a completely flush fit. Message us and we will suggest a matching band.
