Frequently Asked Questions

Learn About 1.7 ct Diamond Rings

Is a 1.7 carat diamond ring big?

A 1.7 carat diamond ring is big, without looking too big. It is over the average carat weight of 1.25 ct, but is becoming far more common due to the lower per-carat cost of lab diamonds. A 1.7 carat engagement ring will look sizeable and adequately cover a decent amount of the finger without looking ostentatious or over the top!

How big is a 1.7 carat diamond in mm?

A 1.7 carat diamond is approximately 7.6mm in diameter if it is round, or often a little larger for other shapes. For example, a 1.7 carat oval diamond ring is typically upward of 8mm.

How much does a 1.7 ct ring cost?

A 1.7 carat engagement ring could cost upwards of £30,000 for a natural diamond - however, the cost is much lower at around £3,700 for a lab diamond ring. The price will vary depending on the ring style you prefer, with simple solitaire ring designs starting at £700, and the rest of your budget can then be dedicated to finding the perfect diamond.

What’s the difference between a 2 carat and 1.7 carat diamond ring?

There is a 0.3 ct difference between a 2 carat and 1.7 carat diamond ring. That equates to around a 2.5mm difference in diameter when viewed from above. This isn’t huge but most people could tell the difference between the two.
