The B.One N°11 ring from the B.One collection is a BELLER design in which the gold gives way to a tourmaline of 0.87 CT. What sets it apart is proportion: an oval of this weight is clearly wider than the two-millimeter band, so from a distance the stone shows as a single mark of color. The stone and the gold are described in the BELLER certificate of authenticity that comes with the ring. For a colored stone such a document matters, because the eye alone cannot confirm the species or weight of a stone.
What tourmaline does the B.One N°11 ring have?
B.One N°11 has a natural tourmaline from Madagascar of 0.87 CT and AAA grade. Tourmaline is a mineral from the borosilicate group that occurs in many colors, and its green varieties are called verdelite. The color of the stone in this ring is natural and does not come from heating or any other treatment.
Is B.One N°11 one of a kind?
Yes. B.One N°11 was made as a single ring, around a single tourmaline of 0.87 CT, only in 14K (585) white gold. There is no version in another gold color or fineness, because the tourmaline was set only once. Later rings in the B.One collection are built around other stones.
Can the B.One N°11 ring be enlarged?
No. The ring comes in one size; we can make it smaller, but it cannot be enlarged. We apply this rule across the B.One collection, and B.One N°11 is currently a size 14, so once reduced it will also fit a narrower finger. We can measure the finger at our boutiques at Mokotowska 71 in Warsaw or Szczepańska 9 in Kraków.
