Attainable and enduring: Firmly in the premium tier without venturing into ultra-rare pricing.

How Big is a 1.5ct Diamond?
Diamond shape, cut quality, and setting style all affect how large a 1.5 ct diamond appears on your finger. Certain shapes, like elongated cuts, can create the illusion of a larger diamond face-up.
Below are the approximate face-up measurements for some of the most popular 1.50ct diamond cuts.
| Diamond shape | Approximate measurements |
| Round brilliant | 7.4mm |
| Oval cut | 9mm x 6mm |
| Emerald cut | 7.5mm x 5.5mm |
| Marquise cut | 12mm x 6mm |

Best Settings for 1.5 Carat Diamond Engagement Rings
As diamond size increases, balance and setting structure become more important.
Cathedral settings: The elevated profile of a cathedral setting is a considered design choice in engagement rings. The centre stone is raised just high enough to allow a plain wedding band to sit flush beneath it.
Hidden halos: A subtle take on the classic halo, this design places a delicate circle of pavé stones around the base of the diamond, visible only from the side.
Thicker bands: A 1.5 ct diamond has the presence to hold its own on a more substantial band. Consider the timeless weight of a classic solitaire shank, or bigger accent diamonds on a side-stone setting.
Claw settings: At 1.5 ct, a diamond still suits relatively fine claws, striking the ideal balance between security and elegance. More delicate claws can still keep the stone firmly held without encroaching on a clean aesthetic.
At Bercotts, every setting is crafted in platinum, yellow gold, rose gold, or mixed precious metals. If you have something specific in mind or a one-of-a-kind piece, our bespoke jewellery design service lets you work directly with expert jewellers.

Natural Diamonds vs Lab-Grown
Natural diamonds are prized for their rarity and the millions of years it takes to form them. Lab-grown stones are created in controlled conditions and typically offer better value at the same quality grade.
At this carat, lab-grown stones can also achieve higher colour grades within the same budget. However, natural stones carry a deeper emotional resonance and enduring investment value that many buyers still seek.
Bercotts guide: Lab-grown vs natural diamond
All our diamonds are graded by independent international institutions: the Gemological Institute of America (GIA) for natural diamonds and the International Gemological Institute (IGI) for lab-grown stones. Every stone comes with a full grading report covering the 4 Cs: colour, clarity, cut and carat weight.
Our collection features larger or more delicate options. Explore our hand-picked selection of 2ct engagement rings, or discover the understated beauty of half-carat diamond rings.
