Diamonds are formed one million miles below the earth's surface and were created by nature over 3.4 billion years ago. They are the oldest substance known today. The diamonds that you will see at Jones & Son are the end result of many years of formulation beneath the earth's surface, years of mining and a lot of time that has been spent cutting the diamonds. When a diamond makes it to one of the world's major cutting Meccas the magic begins. The diamond is shaped from it's original form sown below the octahedral crystal. Only about 40-60% of the original diamond rough is retained in the polished product. The diamond goes through a stringent process to be properly cut. Cleaving, shaping or bruting, and the final touch or stages of the faceting process. This creates the fully faceted product that is used in quality diamond rings and jewelry.
