4C's - carats (carats)
The carat describes the weight of a diamond, not its size. One carat corresponds to 0.20 grams. GISELLE diamonds are always geared towards the cut (maximum sparkle) or exceptionally rare beauty (antique diamonds), not the carat weight.
What does a carat mean in a diamond?
The weight of a diamond is given in carats and not, as is often believed, its size. Therefore, diamonds with the same carat weight can appear completely different in size.
This different appearance is particularly evident in the different diamond shapes. It plays a big role how deep a diamond is cut. For example, a diamond can carry a lot of weight in its stomach and therefore appears smaller. However, the carat weight is a good guide for a set budget. The price increases exponentially as the carat increases, as larger diamonds are much rarer and therefore more difficult to obtain.

No, the carat alone does not determine the value of a diamond. There are large price differences between the same carat weight because other factors such as cut, color and clarity must also be taken into account. Therefore, the beauty and value of a diamond is not primarily defined by the carat alone.
cut
The largest and most important factor in the appearance and sparkle of a diamond. In addition to the different types of cut, the cut means in particular how the light is refracted in the diamond.
color
Color means, among other things, the natural coloring of a diamond.
Clarity
Clarity describes the number, size, type and position of natural inclusions in the diamond. Different inclusions are evaluated differently because not all are equally visible.
FAQs
There is no right and no wrong here. It depends on the wearer.
Most of our customers are attracted to 1ct-2ct (optical). But there are also women who expressly prefer a large size from 3ct, or the complete opposite, women who want a small mini stone (approx. 0.05ct).
If you have no idea what your loved one wants, I recommend buying a diamond from 0.50ct to 1ct. Even on petite women, it doesn't look too big, and if the woman wants a larger look, you could do a so-called upgrading.
Diamonds are measured in carats. One carat equals 0.20 grams.
For a medium budget, we recommend color G/H and Si1 as good standard quality.
Colour:
With white gold & platinum, definitely choose G. With rose gold and yellow gold, an H is also quite legitimate, since the stone takes on a certain yellow tinge due to the alloy anyway.
Purity:
At Si1 you can expect an "eye-clean" diamond. The inclusions are particularly visible under a magnifying glass.
However, we do not recommend going below Si1. The inclusions can be visible to the naked eye and severely affect the sparkle.
