2ct Trilogy Lab-Grown Diamond Engagement Ring
The Karat Store · Handcrafted in Solid Gold
A 2ct pear-shaped lab-grown diamond takes centre stage in the 2ct Trilogy Lab-Grown Diamond Engagement Ring, crafted in solid 10ct, 14ct or 18ct gold. The diamonds are graded F colour, VS2 clarity, for a bright, clean sparkle. The pear cut, or teardrop, combines the brilliance of a round with the lengthening effect of a marquise. The trilogy design uses three stones, often said to stand for your past, present and future. It is one of Britain's best-loved engagement ring styles.
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.
The ring is crafted from luxurious solid gold, with a delicate band measuring 1.8 mm in width and 1.6 mm in height. Designed with a comfort-fit band, it offers both beauty and practicality, making it ideal for daily wear or special occasions. The elegant trilogy design is a classic choice, perfect for those who value refined simplicity paired with ethical craftsmanship. Each diamond is lab-grown, ensuring a sustainable and eco-conscious choice without compromising on luxury or brilliance.
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.
Depending on how low the setting sits, a straight band may leave a small gap. A curved or contoured wedding ring will sit flush. Message us and we will suggest a matching band.
