Ηow much is a 3 carat diamond ring?

What are 3 carat diamonds best for?

A 3 carat diamond elevates any jewellery piece and occasion, so shop GS Diamond’s range today to find the perfect gem for you.

How big is a 3 carat diamond?

Diamonds are sold by weight (carats), but it's important to understand that weight doesn't equally translate into physical size. Two diamonds of the same carat weight can vary greatly in the spread, meaning that one diamond can appear larger than the other, even though they weigh exactly the same. The diameter of a 3 carat diamond is approximately 9.37 mm. The face-up area (how big the stone looks when viewed from the top) would be 68.96 mm². So, while 3 carat diamonds may generally be bigger than a 1 or 2 carat diamond, it is more accurately to say that they are heavier than to say they are bigger. The size truly depends upon the cut and shape of the diamond. If you’re interested in finding out more about diamond size, check out GS Diamond’s top tips on how to save on a diamond ring’s size.

How do I choose the best cut of 3 carat diamond?

The carat weight isn’t the only thing that determines the quality and appearance of your stone. Instead, the cut, colour, and clarity of the diamond determine the real visual effect of your chosen diamond. You may be able to save on costs by choosing a different shape of diamond. Round diamond rings are the most popular option for many people, but they’re also the most expensive per carat, because they require the removal of the most amount of material from the rough. Choosing an oval shape may save you over 30% of the total cost, while an Asscher diamond can help you save 40%. If you’re unsure of how to choose a diamond, contact our friendly team for assistance or visit us in one of our Australian stores — we’ll be happy to help you with anything diamond-related.
