Tips for Buying a 4-Carat Princess-Cut Diamond Ring
If you’ve decided to invest in a 4-carat princess-cut diamond, then there are a couple of factors you should consider. Diamonds that weigh four or more carats are known for their brilliant sparkle. To maximize the shine, choose a diamond that has been precisely cut. If possible, then look for a 4-carat diamond with VS1 or VS2 clarity. When it comes to the color-grading scale, select a stone that is colorless or nearly colorless.
Buying a 4-carat princess-cut diamond is a huge investment. Expect to pay anywhere from $30,000 to $250,000 for a diamond of this size. Of course, other factors determine the price, like the color, clarity, cut, and availability of the diamond itself.
The good news is that princess-cut diamonds are extremely popular, so finding one that meets all your requirements shouldn’t be too challenging. In terms of settings, princess-cut diamonds look best on solitaire rings, but they can be just as beautiful in other designs.
