Diamonds are among nature’s most precious and beautiful creations
Diamond forms under high temperature and pressure conditions that exist only within a specific depth range (about 100 miles) beneath the earth’s surface. It takes about a billion years for a Diamond to be formed. Every Diamond is Absolutely Unique. Each reflects the story of its arduous journey from deep inside the earth to a cherished object of adornment.
Diamond’s characteristic chemical composition and crystal structure make it a unique member of the mineral kingdom. Diamond is the only gem made of a single element: It is typically about 99.95 percent carbon. The other 0.05 percent can include one or more trace elements, which are atoms that are not part of the diamond’s essential chemistry. Some trace elements can influence its color or crystal shape. Diamonds are valued for their colorless nature and purity. Most diamonds are primeval—over a billion years old— and formed deep within the earth with temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface.

The "Pink Star" Diamond - 132.5 carat rough was cast in epoxy more than 50 times in order to create models upon which the design team could experiment with different cuts - it was transformed into this spectacular 59.60 carat, fancy vivid pink, internally flawless oval-cut gem – the largest internally flawless or flawless, fancy vivid pink diamond that the Gemological Institute of American (GIA) has ever graded.
The "Winston Blue" - The largest known pear-shaped fancy vivid flawless blue diamond in the world weighing 13.22 carats. One of the rarest diamond GIA has ever graded.
The "Hope Diamond" - The history of the stone which was eventually named the Hope diamond began when the French merchant traveler, Jean Baptiste Tavernier, purchased an 112 3/16-carat diamond. This diamond, which was most likely from the Kollur mine in Golconda, India, was somewhat triangular in shape and crudely cut. Its color was described by Tavernier as a "beautiful violet." The Smithsonian is home to the 45.52-carat "Hope Diamond", the world’s largest deep blue diamond. Harry Winston bought the diamond and donated it to the Smithsonian. Today the Hope Diamond is one of the most visited museum objects in the world.
