When you are looking to buy a diamond ring or choose a very specific diamond to make a custom ring, it is extremely difficult to navigate and understand the price of a diamond based on its quality criteria assessed by the famous 4Cs.
This article allows you to discover in detail the quality criteria of a 0.25 carat G VS2 diamond, visually according to the high magnification photos presented and through its quality certificate established by the GIA laboratory.
Observing diamonds is often a difficult thing, requiring adequate knowledge and the eye to spot flaws.
This is even more difficult when looking at diamonds online because photos often misrepresent the diamond’s brilliance and these flaws. Furthermore, shooting diamonds is a complex thing.
We therefore present here a G color and VS2 quality diamond taken with special equipment to obtain very high resolution photos that reflect the quality of this GVS2 diamond.

If you want to know more about the quality criteria of diamonds, I invite you to read this article which explains the 4Cs of diamonds.
This other article will explain the difference between natural diamonds and synthetic diamonds.
Here are some examples of diamond rings made in our goldsmith workshop:
Views of the diamond from different angles
Close-up view of the G color and VS2 clarity diamond showing its facets and the light reflections they cause. The 57-facet brilliant cut that is the standard today was discovered by Marcel Tolkowski in 1919. I invite you to read this very interesting article on the brilliant cut of diamonds.

The diamond has a diameter of 4 mm, the photo presented above corresponds to an X15 magnification which allows us to see some defects in the diamond that are completely invisible to the naked eye and difficult to see with an X10 magnification.
This side view of the diamond allows us to appreciate its color, the quality of the diamond cut and to see some flaws in its clarity. This photo corresponds to a 22.5x magnification.
Finally, this view of the breech allows you to appreciate the diamond from all angles. This photo corresponds to a X16 enlargement of the diamond.
Diamond certificate
As with all diamonds of this quality, the diamond certificate is established by an independent body, in this case the GIA, which certifies its size, weight, colour, clarity and cut quality.
We can make the following observation about the importance of diamond cut quality in restoring diamond brilliance. This criterion is often more important than the color of the diamond in giving this strong brilliance effect to the stone.
0.25 Carat G Diamond Price
The price of such a diamond varies depending on the quality of the cut and the retailer. Indeed, depending on the margin of the wholesaler, the jeweler or the reputation of the jewelry brand, whether it is mounted or not, the price of the diamond will vary.
Roughly speaking, the price of such a diamond will start from around 500 euros and will be sold at a higher price if the cut quality is even better in terms of symmetry (see certificate above).
