DESCRIPTION
A binomial is simply the sum or the difference between two parts, for example a+b or a-b. The binomial formulas (a+b)2 and (a-b)2 are derived from this.
Our “Binomial” signet ring is crafted from high-quality 316L stainless steel in antique silver with an inlay of black and white marble. The white veins in the marble reveal the history of its origins from millions of years ago, and also ensure that your own piece is an absolute one-of-a-kind. Discover your new daily companion and wear your own personal piece of raw nature by your side!

What makes Holzkern special
Core Features

marble
A touch of luxury. The name "marble" comes from the Greek word "mármaros", which means "shining stone". The history of marble dates back to ancient Greek and Roman art, where marble was used for sculptures and architecture. With its distinctive texture and coloring, marble provides a particularly aesthetic appearance that makes our watches and jewelry made from this stone very special statement pieces.

Perfect for Sets
Birds of a feather flock together. Combine this product with other colors from this collection or necklaces, bracelets, rings or earrings in the same design. Discover all the unique pieces in this collection and complete your one-of-a-kind jewelry set!
