Champagne and diamonds are most likely two words a girl cannot hear enough of and when put together in a jewelry sense, wonderful thoughts happen! Diamonds are a girl's best friend, so I am told. Champagne diamonds are an even better friend if you ask me.

A genuine diamond is carbon in the most concentrated form. Except for some diamonds that are high in impurities like boron and nitrogen, a diamond is composed solely of carbon, the chemical element that is fundamental to all life.

A pure, perfect diamond is colorless, or near colorless, but when nitrogen is added a yellow color appears. Add boron instead and a blue diamond will be the result. Colors can range from red to violet, which are extremely rare however but pinks, champagne's and black diamonds are also possible.

Every single color of the rainbow corresponds to a particular energy in the atmosphere and it's surroundings. When the energy of light entering a diamond equals the amount needed to jump start an electron, colors start to appear.

A perfect or colorless diamond exists because visible light lacks sufficient energy to boost any of its electrons, therefore no light is absorbed. However, impurities like nitrogen, boron or hydrogen, as well as structural flaws, can create electron states which can be effected by the energy in visible light. Take a yellow diamond for example, the higher energies of violet and blue light are subtracted from white light making the diamond appear that yellow color.

A champagne diamond can be a very light beige color to a deep golden color, even a dark brown, ultimately called "cognac diamond" or "chocolate diamond" which has become very popular on the market these days.

Abnormal stress while the diamond is being formed will cause a stone to appear as a champagne diamond. If the crystalline structure is subjected to unusual compression as the gems are forming, an almost opaque yellow hue the same as fine champagne can form. This is the same process that can also form red or pink diamonds.

Some champagne diamonds have a secondary tint of pink, and the combination of both shades is the most valuable of all. This shade of champagne is usually found in smaller stones or a size commonly referred to as "points" but viewed under a diamond loupe will display it's fiery pinks, gold's and beige's.

Like all diamond colors, champagne is not a single hue or tint. It is more of a brown and yellow combined with beautiful clarity. I chose a champagne diamond for my wedding ring, and made a few discoveries along the way. My ring was yellow gold, with a bezel style setting, which ultimately drowned out the beautiful fire in my champagne diamond. So I suggest setting a champagne diamond into a platinum or white gold setting, which I later did. Also a higher mount will allow the natural light to create a stunning brilliance of your stone.
