Our diamonds
Roosik Diamonds
The bewitching power of the most incredible brilliance. Is there anyone not fascinated by the intensity of light? The bright sparkle of the stars at night or dazzling sunlight reflected on the sea at midday: like the light of the purest diamonds. And at Roosik&Co. we turn them into signature pieces of jewellery that light up your life, forever.
Les 6 C de Roosik
In jewellery, the so-called “4Cs” (cut, clarity, carat and colour) determine a diamond’s perfection. The quality of the cut and clarity, a diamond’s carat weight and its colour all make a diamond especially brilliant with outstanding luminosity. But at Roosik&Co. we’ve added another 3 features to the 4Cs, thanks to the triple excellence of all our diamonds, the conflict-free diamonds and the guarantee&certificated provided by Jordi Rosich, gemologist expertise, personally selecting all the stones we use. Because we love the jewellery we create as much as you do.
1 C's GIA · Colour
2 C's GIA · Clarity
If a diamond has no impurities when viewed under ten times magnification, it’s said to be flawless and nothing can alter its optical properties. That’s why Roosik&Co. always recommends diamonds from the VVS2 category and above.
| F | IF | VVS1 | VVS2 |
| Fawless | Internally Fawless | Very Very Slightly included | Very Very Slightly included |
3 C's GIA · Cut
Whether a diamond’s cut is emerald, round brilliant, oval or princess: the symmetry, proportion and polish of its different faces ensure a diamond’s cut is excellent and reflects 99% of the light that shines on it.
4 C's GIA · Carat Weight
One carat equals 200 mg and is the unit used to measure the weight of a diamond. A diamond’s value is determined by the number of carats but it’s always better to choose a size that matches the personality of the person who’s going to wear it.
5 C's ROOSIK&CO · Ideal cut diamonds
Roosik&Co’s diamonds are always triple excellence: their symmetry, cut and polish are impeccable. Only then can the stone completely scatter the light that penetrates it, making the diamond sparkle and shine like a star.
