About Natural Diamonds

The iconic crystal clear, multifaceted, sparkling diamond is one of the most famous and infamous precious gemstones on earth. Long sought after by royalty, financiers, and the world’s elite, they have becomes ensconced in the everyday collections of millions of men and women across the globe. Diamonds have traditionally served the purpose of adorning crowns, jewelry, and serving as a condensed form of wealth for millennia.


The name “diamond’ comes from the Greek root for the word “unbreakable”, as it is the world’s strongest substance. It is not formed from coal, as literature and modern aggrandized lore has the public believe. Diamonds are formed under the earth’s mantle over the course of millions of years of pressure on the metastable allotrope of carbon which causes the formation of a repeating geometric pattern of pure carbon, arranged in a crystalline lattice. In their most basic form, diamonds appear colorless and are considered the most beautiful when they display the least amount of imperfections and color that nature is willing to bestow. However, a rare occurrence in the diamond world is the 1 in 10,000 occurrence of color in the substrate of carbon due to the introduction of additional natural elements to the diamond’s structure. For example, the presence of radioactive isotopes will turn a diamond green, and the introduction of boron will turn a diamond blue. A diamond can appear pink or red when it undergoes an extraordinary additional level of pressure when it is being formed, and when nitrogen is present a diamond can display brown, yellow or orange color. It is also possible for a diamond to exhibit a combination of colors, although those combinations are entirely governed by the color wheel of nature.

Regardless, the traditional colorless diamond is sought after across the globe for its beauty, strength and practicality. Having been the subject of both many a gift and many a subterfuge or heist, diamonds have grown considerably in desirability over the millennia and have taken a permanent standing in culture and romance around the world. Due to their prevalence, a universal grading and identification system for diamond characteristics was developed, called the 4Cs. The color, cut, clarity and carat weight of any diamond is evaluated, and its value is determined based on its exhibition of these four factors. Just because a diamond may weigh many carats, it may not be as valuable as a diamond that has flawless clarity and perfect color. Their color is graded on a scale from D-Z, D being the highest grade and Z already exhibiting a significant degree of yellow. Color diamonds are graded on a different scale entirely, depending on whether they display their color strongly (Fancy Deep or Fancy Vivid) all the way through a faint appearance (Fancy Light or Faint).


Although colorless diamonds are a class of their own, they are often most beautifully represented when paired with color diamonds. Often, a color diamond piece of jewelry will be enhanced by the inclusion of colorless diamonds around it or alongside it. Conversely, colorless diamond jewelry often is more beautiful when they are surrounded by color diamonds or color diamonds are displayed alongside. Leibish & Co. carries a wide selection of both colorless diamond center stones and side stones or melees.
