1.5ct Lab Grown Diamond Engagement Rings
The 1.5 carat diamond is the choice of those who want something unmistakably more — more presence, more brilliance, more impact — without stepping into the statement territory of a 2 carat stone. It is the ideal middle ground: noticeably larger than the classic 1ct, beautifully proportioned, and extraordinarily brilliant on the finger. At Alan Bick, our 1.5ct lab grown diamond engagement rings make that upgrade effortless.
What is a 1.5ct lab grown diamond?
Lab grown diamonds are chemically, physically, and optically identical to natural diamonds — real diamonds, certified by the IGI and GIA to exactly the same standards, with the same brilliance, fire, and durability. At 1.5 carats, choosing a lab grown diamond over a natural equivalent delivers a meaningful saving, freeing your budget to invest in a superior colour and clarity combination — or a more intricate, diamond-set ring design.
A round brilliant 1.5ct diamond measures approximately 7.4mm in diameter — noticeably larger than a 1ct stone, with significantly more light return and visual impact. In an oval cut, it reaches around 9.5mm x 6.5mm, delivering an elegant, elongating effect on the finger that has made the oval cut one of the most sought-after shapes in modern bridal jewellery.
