color
From colorless to yellow or brown, there is a wide range of diamond colors. At Roosik & Co we only work with Colorless diamonds (groups D, E, F), making our jewelry pieces even more beautiful.

Purity
If a diamond has no impurities when viewed ten times magnified, it is said to be flawless and nothing can alter its optical properties. This is why Roosik&Co always recommends diamonds of the VVS2 category and above.

size
Whether the cut is emerald-shaped or round brilliant, oval or princess: the symmetry, proportion and polish of the faces will make a diamond cut excellent, thus reflecting 99% of the light that penetrates it.

Carats
One carat is equivalent to 200 mg, and is the unit for measuring the weight of a diamond. The carat determines the value of a diamond, but it is advisable to choose a size that suits the personality of the person who will wear it.

Triple excellence
Roosik & Co diamonds are always of triple excellence : the symmetry , the cut and the polish are impeccable. Only in this way is it possible to achieve total dispersion of the light that penetrates them and for the diamond to shine like a star.

GIA certificate
In addition, all diamonds used are accompanied by a certificate of authenticity , attesting to the guarantee and excellence of the stones. An official certificate from GIA (Gemological Institute of America) for all diamonds over 0.30 carats and a certificate issued by Jordi Rosich, a qualified gemologist and diamond specialist, for all diamonds under 0.30 carats.
