Measurements of a Round 1.8 carat diamond are approximately 7.91×7.91×4.77 mm. But please note: the cut of a diamond is not its shape, but rather its proportions, symmetry, measurements, and facet placement.
The cut can affect the way light is reflected in the diamond, so a high quality cut can create a beautiful sparkle. For example, Round diamonds typically look larger when viewed from the top than Emeralds, Radiants, and Cushions. But Oval, Pear and Marquise diamonds have a larger surface area, while Princess and Asscher cut diamonds are smaller.
The wider the band of the engagement ring, the smaller the 1.8 carat diamond will look. Conversely, the thinner the band, the larger and more impressive the 1.8 carat diamond will appear. For that reason, one of our most popular styles is Dalia Petite Diamond Engagement Ring 4 Claw. A delicate band really lets your diamond's brilliance and sparkle take centre stage, while also making it look bigger.

Yes, absolutely. It’s a very good size for engagement rings – not too big and not too small.
Round diamond rings are the most popular option for many people, but an oval shape would save you over 30% of the total cost. An Asscher diamond can help you save some 40% on the total cost. Round brilliant-cut diamonds are the most expensive per carat because they require the removal of the most amount of material from the rough.
