The small roulette ring is the classic among the ball rings - but just a little better. Due to the flattened and rounded inner rail, it is comfortable to wear and still has this somewhat edgy hip look on the outside. The must have for any stacking but also a great symbol for the many important moments in life or a ring you might want to wear together with your most important people. Made of 18 Karat gold. 1.3 mm wide. This ring is made by hand with much love and care in the Rivour & Guya studio in the Black Forest, Germany. The gold used in all Rivour & Guya rings is ecologically river gold from Germany, mixed with recycled gold (Mass Balance Principle). The diamonds used in Rivour & Guya are of a very high quality. The diamonds are at least the G color and SI clarity and they all come from Canada (Deviak and Ekati mine) and are cut exclusively in RJC certified manufactories.
