4C's - Clarity
Clarity is a measure of the natural occurrence of inclusions in a diamond. The inclusions are evaluated for visibility, number, position and type under 10x magnification.
What does diamond clarity mean?
Diamonds are judged based on their natural occurrence of inclusions. Inclusions are imperfections inside a diamond. The inclusions are like a diamond's fingerprint and are always unique.
FL diamonds are flawless (Flawless)
IF diamonds are internally flawless
VVS Diamonds (1 & 2) have Very, Very Slightly Included
VS Diamonds (1 & 2) have Very Slightly Included
SI Diamonds (1 & 2) have Slightly Included

If there are too many inclusions, it can affect the refraction and reflection of light, which can make a diamond appear dull. You are on the safe side with a VS2 and higher, except for the step-cut diamonds you need VS1 and higher. But if you want an Si1, I recommend only getting it from a specialist to avoid getting a nasty surprise in the end. In my opinion, Si2 and lower is not recommended. It spoils the sparkle of a diamond too much.
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.
carats
The carat describes the weight of a diamond. Not, as many mistakenly think, the size.
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.
