About 0.7 Carat Diamond Rings

A 0.7ct engagement ring is considered a real sweet spot in terms of a diamond that is reasonably sized and relatively budget friendly, compared to diamonds over the 1ct mark. For a long time, 0.7ct engagement rings were the average diamond size for couples in the UK - although this has increased to around 1ct with the emergence of the less costly lab diamond alternatives.

A 0.7ct engagement ring features a main diamond that weighs the equivalent of 140mg, and is shy of a full carat by 0.3ct. A 0.7ct round diamond has a length around 5.68mm, or 7.2mm or more for popular elongated shapes like oval diamonds and pear diamonds.

Frequently Asked Questions

Learn About 0.70ct Diamond Rings

What is a 0.7 carat engagement ring?

A 0.7 carat engagement ring indicates that the centre diamond weighs 0.7ct. A carat is a measurement of a diamond’s weight - a 0.7ct diamond is 0.3ct less than a full 1ct diamond. The weight of 0.7ct is equivalent to 140mg. Perhaps a more useful indicator; a 0.7ct round diamond is around 5.68mm in length.

How much does a 0.7 carat diamond ring cost?

The price of a 0.7 carat diamond ring starts around £1,900, so could be the perfect option for those with a top ring budget of £2K.

A good quality 0.7 carat diamond costs £1,200 if it’s a loose lab grown diamond, or £3,200 if it's a loose natural diamond. The total price of a 0.7 carat diamond ring will have the additional cost of the ring setting itself, starting at £700.

Please note that diamond prices fluctuate, and this should be used as a guide price accurate at the time of writing.

How big is a 0.7ct engagement ring in mm?

A round 0.7ct diamond is around 5.68mm in length, or upward of around 7.2mm for shapes like ovals and pears; which is by no means small nor huge. A 0.7ct diamond engagement ring is considered a fairly average size for ring buyers in the UK - although the average has increased a little since the emergence of cheaper lab diamonds that allow buyers to afford a bigger gem for their budget.
