Diamond Prices and Pricing Factors: Complete Guide

But remember: Only compare prices for COMPARABLE cheap condo for sale in bangkok diamonds! However, as we already mentioned, there are additional factors that can make diamonds sell at different prices even though they have the same color, clarity, cut, and carat. These are the basic features on which diamonds should be identical in order to be compared. After you make sure that you’ve taken into account all these characteristics, there might still be a price difference that is unaccounted for.

Girdles that are very thin are prone to chipping. Diamonds with girdles that are in the middle of the road – i.e. not too thick or thin – sell at a premium. Many diamonds nowadays are not cut with culets. This is a diamond diagram from an actual GIA certificate. The most optimal situation for a stone is either to have no culet or to have a small one. The culet is the facet at the bottom of diamond. The red arrow points to the girdle grade for this particular stone. Big culets are visible through the top of the stone and can impair its pattern of light return – such stones may sell at a discount.

Now, if you check the prices at most diamond retailers, the price you will be given for any particular stone will most likely be a total price, not per carat. But these prices are still based on per-carat prices quoted among diamond dealers. While diamond prices go up when carats increase, you can see that prices jump sharply at popular carat numbers such as 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00 carats, and so on. For example, if a 0.45-carat diamond sells for $1,200 and a 0.46-carat stone sells for $1,250, a 0.50-carat diamond will cost $1,650.

These two diamond are nearly identical except for their carat weights – one is 0.70 ct while the other is 1.50 ct. Color is another quality factor that affects the price of a diamond. Generally, the more colorless a diamond, the more expensive it is, all else being equal. Colorlessness here refers to the absence of yellow or other tints in the stone. You can see how dramatic the price difference between them is.
