Refractive Index


Different gems or substances have varying refractive indexes. Diamond's is unique in the sense that it has the high refractive index of 2.417. Cubic zirconia's is about 2.15. The higher the RI (refractive index) the more ability it has to bend light. Light bends because the specific material structure slows it down as it enters. We see this in the dislocated image of an object immersed in a liquid, such as the apparent bending of a straw sitting in a glass of water. In vacuum conditions (such as interstellar space), light travels at approximately 186,000 miles per second, with an effective refractive index of 1. Once light hits our atmosphere, it slows down slightly due to a refractive index of 1.00029. Through diamond, light travels at closely 77,000 miles per second (186,000/2.417).

   Timepieces can be a trendy market but we have the knowledge and experience to bid quotes that satisfy our sellers and leave a small profit to run our business. We are not watch snobs so we have expanded broadly outside of the typical "we only buy Patek, Rolex and Cartier" mentality.

   We are consistently expanding our knowledge and buying power into areas that have been both interesting and very marketable. A few years ago we would have never guessed we would be buying high-end clutch bags and figurines. Feel free to contact us with as much information as possible regarding your valuable small collectible.
