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!
