B.One N°12 is a BELLER ring from the B.One collection, set with a tourmaline of 1.06 CT. Scale is what defines it: a stone of this weight on a band 2 mm wide becomes a clear center on the hand, with no side stones to support it. The ring was made only in 14K (585) yellow gold, with no color or size options. A numbered BELLER certificate of authenticity describes this stone and the gold of the ring.
How much does the tourmaline in the B.One N°12 ring weigh?
The tourmaline in B.One N°12 weighs 1.06 CT, and the whole ring about 1.9 g. The CT unit describes the weight of a stone, not its dimensions, although within the same variety a greater weight usually means a larger stone. A stone's weight is measured before it is set, because once it is held in gold it can no longer be weighed precisely.
Is the tourmaline in B.One N°12 natural?
Yes. The tourmaline in B.One N°12 is a natural AAA-grade stone, unheated and untreated, which we sourced from Madagascar. Its color and transparency come from the crystal itself, with no procedures to improve the appearance of the stone. The question matters with tourmalines, because in the trade stones of this variety are sometimes heated or irradiated to change their color.
What size is the B.One N°12 ring?
B.One N°12 is a size 13, the only size in which it was made. The ring comes in one size; we can make it smaller, but it cannot be enlarged. When it is reduced, the yellow gold band keeps its width and shape, and only the circumference of the ring changes. Size 13 is therefore the largest size this ring can ever have.
