FAQs about 1.5 Carat diamonds

There are many factors that affect loose diamond prices, including shape, colour, cut, clarity, and carat. Round diamonds are more expensive per carat weight than the nine fancy diamond shapes.

The shape and individual cut of a diamond determine the size of the stone. On average, a one-and-a-half-carat round diamond will measure 7.4mm in diameter, while an oval cut measures 9mm x 6mm. Blue Nile offers a half-carat diamond size chart that illustrates the differences in all shapes and sizes.

The 4 Cs are carat, colour, clarity, and cut. Carat impacts the price the most, but when you want to maximise brilliance, the cut grade is the most important.

One of the best ways to make your budget go farther is to "buy shy" and look for diamonds that have a carat weight of just under 1.5 rather than a 1.5 carat weight.
