3ct Lab Grown Diamond Engagement Rings

3ct Lab Grown Diamond Engagement Rings
A 3 carat diamond is the ultimate statement — bold, breathtaking, and impossible to ignore. At Alan Bick, our 3ct lab grown diamond engagement rings offer exactly that level of brilliance, at a fraction of the price of an equivalent natural diamond.
What is a lab grown diamond?
Lab grown diamonds are chemically, physically, and optically identical to natural diamonds — created using advanced technology that replicates the conditions under which diamonds form deep within the earth. They are graded to exactly the same standards by the same independent gemological laboratories, including the IGI and GIA, and are certified accordingly. The only difference is where they come from — and the price.
At 3 carats, the price difference between a natural and lab grown diamond is significant, making a 3ct lab grown diamond ring one of the most compelling choices for anyone who wants maximum size, quality, and impact within a considered budget.
Our 3ct Lab Grown Diamond Rings
Every ring in this collection is made to order in our Hatton Garden, London workshops, set with a hand-selected 3ct lab grown diamond in your choice of cut — from the timeless round brilliant to the elegant oval, the striking radiant, and beyond. Each diamond is IGI certified and selected for its colour, clarity, and cut quality, ensuring exceptional brilliance in every stone.
Choose your setting, your metal — 18ct yellow gold, white gold, rose gold, or platinum — and your diamond, and we will craft your ring to your exact specifications.
