FAQ:

Q: What is the best carat for a diamond ring?

A: Almost one carat, 0.90 cts is a popular choice for those looking to save on a one-carat diamond. Unless someone’s measuring your diamond, they’ll never know that it’s below 1.00 ct, and the jump in pricing at the one-carat mark makes this diamond weight appealing to those looking for savings.

Q: How important is carat weight when buying an engagement ring?

A: For an engagement ring, expectations about carat weight are often at odds with the reality of diamond prices. Consider your options carefully and remember that even rings with small diamonds can be elegant and sparkly. Furthermore, telling the difference between small changes in weight can be difficult.

Q: What do carats measure on a diamond?

A: Keep in mind that carats measure a diamond’s weight, not its dimensions or size. However, you can get an idea of the size of a round diamond by its carat weight.

Q: How much does a 5+ carat diamond cost?

A: If only a celebrity-sized diamond will do, then a 5+ carat stone is what you’re looking for. At this weight, diamonds are not only eye-catching and large but also rare, and it’s even more difficult to find one with great performance. At this size, budget $60,000 to $100,000 for a well-cut diamond.
