How the 4Cs influence the cost of diamonds

If you are planning to propose, you have to decide how much you are willing to spend on the engagement ring, especially if you want a diamond ring. While diamonds are not cheap, they are sometimes overpriced, and you might end up overpaying for a lower grade diamond. In this blog post, we will be getting into the nitty-gritty details that determine diamond prices to help you get the best value for your money.

Diamond prices based on the 4Cs

If you do not know what the 4Cs are, go through <a href=https://www.silkroaddiamonds.co.uk/blogs/news/the-four-c-s-quick-reference-guide>our guide</a> first.

Diamond Clarity

The clarity grading system takes into account the position, size, and type of inclusion/ blemish before finalising the price. However, as expected, higher grade diamonds cost more money because they have more sparkle and brilliance and fewer blemishes. Diamonds between FL and IF in the clarity grading system are the most expensive, and the price reduces as you get to the I1, I2, and I3.

Diamond Cut and shape


A diamond’s cut influences its brilliance and sparkle, and therefore its price. The popularity of a cut also affects the final cost of a diamond, which is why round cut diamonds are much more expensive. This is because a large amount of rough diamond is wasted during the cutting and polishing process. Jewellers charge more for a diamond if there was a larger wastage of rough diamond.

Diamond Colour

A structurally perfect and chemically pure diamond has no hue. Therefore, the more colourless a diamond is, the higher the price. The GIA diamond colour grading system ranges from D to Z, D being colourless and Z being brown. That being said, the phenomenon of fluorescence also affects diamond pricing. Fluorescence is how a diamond reacts under UV light. Stones with low fluorescence produce a soft light blue light, while those with high fluorescence have a white milky effect. It can decrease the value of stones in grades D to F and increase the value of those between G to J.

Diamond Carat

Usually, diamond price increases with the diamond carat weight. A 2-carat diamond ring will be pricier than a 1.5-carat diamond ring, but the final price is influenced by all four factors.
