What this shows is that the difference in price in 1 carat and a 3 carat diamond, is not a straightforward multiplication of the prices due to the non-linear escalation of diamond prices. The cost of a 3 carat diamond ring ranges from $ 20,000 to$ 200,000, perhaps even more. The  cost is due to several factors namely the shape, the precision of the profile, clarity, and colour.

What part does the shape of a 3 carat diamond play in pricing?

Round brilliant cut diamonds are always praised for their timeless loveliness and unparalleled brilliance. Fancy shaped diamonds such as emeralds, asschers and queens are always cheaper for the same type of quality and carat weight.

Asscher cuts on step-cut angles at the expense of brilliance for clarity. producing a classic and elegant look though at a rather more affordable price point. Queen cut diamonds are characterized by a very modern geometric appearance. imported with superb brilliance at a price that competes with the price of round diamonds.

If the size of the carat of a diamond grows, more surface area is displayed. thus revealing flaws in its cut. Each angle, each proportion in the cut of the diamond is critical to creating the necessary amount of sparkle.

Outside the cut, the clarity of a 3 carat diamond is largely dependent upon the quality affecting its value. With the increase in carat weight, the diamond’s table increases and so you see deeper into the stone. As the clarity is judged on the number and the size of imperfections, it should always be the prime option to consider when selecting an eye-clean diamond.

In this respect, choosing diamonds from VVS1 to VS2 clarity range is usually the best option.
