Above are a selection of links to vendors where you can check the current prices of 1 carat diamonds. I’ve selected these vendors as they have enough inventory to be able to show you the prices for the respective shapes linked to. Where feasible I’ve customized each respective link to exclude as many diamonds as possible which I would not recommend so you will not be shown diamonds with poor symmetry, poor polish, nor ones with strong fluorescence. This will give you a more realistic expectation as to what you can expect to pay for a diamond when shopping online. For brick and mortar prices just multiply the prices you see online by 1.3 to give you a realistic expectation of the retail prices in physical jewelry stores.

What is a 1 carat diamond?

A carat is a unit of measurement used to describe the weight of precious gems, including diamonds. It’s exactly 200 milligrams, so five carats is equal to 1 gram. Even though that seems like it’s hardly anything a 1 carat diamond can be cut into certain shapes that make it look slightly bigger or smaller depending on the skill of the cutter and the design itself.

How big is a 1 carat diamond?

A round brilliant diamond will have an average diameter of 6.4mm. There are various factors which affect the size of a 1 carat diamond. If a diamond has been given an extremely thick girdle then this will detract from the diamond’s overall spread. It can also be cut with very steep angles which affect the spread negatively. It’s also possible for a diamond to be cut with obtuse angles but this will usually result in the diamond leaking light through the bottom of the stone, so a happy medium must be achieved by the cutter.

Does an oval 1 carat diamond look bigger than a 1 carat round brilliant?

A 1 carat oval cut diamond gains an average of 0.9 mm in length but loses an average of 0.7 mm in width. So the difference is approximately the same as the difference between a 6.4 round diamond and a 6.6 round diamond. So an oval will look about 3% bigger than a round brilliant of equal weight all else being equal. Of course there will be variables which will affect the spread of an oval just there are with a round brilliant. If it is given a super thick girdle then it will lose spread, if it is a deep cut then it will also lose spread.

What is the cheapest 1 carat diamond?

The price of a 1 carat diamond will vary depending on what color it is, and how pure and clear the diamond material is. The way a diamond is cut, also affects the price. This is because certain shapes are closer to the way a diamond was formed in nature and less of the diamond has to be cut away to reveal the final shape. So you will find that other shapes, such as cushion, princess, pear, etc, are lower in price per carat, all else being equal.

The geometry of a round brilliant diamond creates the most brilliance and for this reason it has remained the most popular shape in spite of some other shapes being lower in cost per carat.

As prices of diamonds are based not only on the diamond’s weight there are some 1 carat diamonds which are cheaper than others. The cheapest 1 carat diamond will be a very “warm” color, and have a great deal of inclusions visible to the unaided eye. Most merchants only stock K as the lowest color grade. The diamond will usually be something other than a round brilliant cut. –If you want the cheapest 1 carat diamond, that is.
