Thinking of an engagement ring might evoke an image of a colorless diamond solitaire. Although that is certainly a classic choice, there are many other options when it comes to getting engaged. Engagement rings are highly personal items of jewelry and can be set with colored stones as well as colored diamonds rather than colorless ones. The 2017 trends saw a marked increase of interest in non-solitaire rings. Similarly, fancy yellow diamonds have grown in popularity over the past few decades. These gorgeous gemstones can be set in antique style settings as well as modern ones. If making the decision between a fancy yellow diamond versus a colorless diamond is a tough one for you, we’re here to help.

Diamonds are a mineral that is composed of 99.95% carbon. The remaining percentage is trace elements, some of which can affect a diamond’s color. One of the trace elements that can be found in diamonds is nitrogen, which is the source of a yellow diamond’s color.

Colorless diamonds are graded for their color on a scale D-Z, with D being the most transparent, like a drop of pure water. A vast majority of diamonds are graded somewhere between D and Z, which is to say that most diamonds have varying degrees of trace nitrogen. Diamonds which have no nitrogen at all are extremely rare. However, intensely colored or “fancy” yellow diamonds are even rarer than colorless diamonds.

Fancy colored diamonds are not graded on the D-Z scale. For instance, yellow diamonds are graded on a special scale: fancy light yellow – fancy yellow – fancy intense yellow – fancy deep yellow – fancy vivid yellow.

Jewelry connoisseurs associate Tiffany & Co. with fancy yellow diamonds nearly as much as their trademark blue color. In fact, for quite some time Tiffany had exclusive access to yellow diamonds mined in Ellendale, Australia – the largest yellow diamond mine until it closed in 2015. The world-famous Tiffany Diamond was mined in 1877 in South Africa. Once cut and faceted, this impressive fancy yellow diamond weighed a whopping 128.54 carats. It was once set in an enchanting necklace by jean Schlumberger for Audrey Hepburn to wear while promoting the film Breakfast at Tiffany’s. Remarkably, this famous yellow diamond was never sold, and remains on display in Tiffany’s flagship Fifth Avenue store.

Today, yellow diamond rings are rising in popularity. Many celebrities flaunt their sparklers of the rising sun wearing fancy yellow diamond engagement rings, yellow diamond wedding bands, and yellow diamond right-hand rings. Some of them include Kelly Clarkson, Jennifer Lopez, Carrie Underwood, Hillary Clinton, Heidi Klum, and Rebecca Romjin.

Our culture already attaches certain symbolism to diamond rings. The striking color of fancy yellow diamonds only adds to the meanings of strength and eternity. Yellow diamond engagement rings evoke joy, happiness, and prosperity. Therefore, yellow diamonds make a fantastic choice for an engagement ring.

What’s So Special About Colored Diamonds?

You might wonder why diamonds come in different colors, and what makes them so expensive. The mineral diamond is a pure form of the element carbon. The appearance of color in a diamond is caused by either trace elements or internal distortions that are included in the crystal as it forms. Although most faceted (cut) diamonds appear to be white, many diamonds that are mined are actually a faint shade of yellow.

Diamond color is graded on a scale from D to Z. Diamonds with a color grade of D, E, or F are considered colorless. Grades G-J are near colorless. Diamonds that fall in the K-M color grade range have a faint yellow tint. The N-R range has a very light-yellow tint, and the S-Z range is light yellow.

Diamonds can occur in almost any color of the rainbow, but fancy color diamonds are much rarer than white diamonds. Their color intensity is graded from Faint at the lower end to Fancy Vivid at the high end.

Yellow diamonds are one of the most popular fancy colored diamonds, and their color is caused by the trace element nitrogen. Because of the way diamonds form, it’s rare for a diamond not to contain any nitrogen at all; hence the rarity of truly colorless diamonds. On the flip side, a deep saturation of nitrogen creating a “canary” bright yellow color is also rare.

Brown diamonds are the most commonly occurring fancy-colored diamonds. Brown is caused by internal graining, a distortion in the diamond’s crystal structure. This same kind of distortion is also responsible for creating pink and red diamonds. Red and blue are the rarest colors of diamonds. Less than 20 diamonds have so far been certified as red diamond and only 20-30 have ever been mined. Blue diamonds are colored with the trace element boron.

Fancy white diamonds are caused by the scattering of light by thousands of microscopic pinpoint inclusions and have an opalescent look that sets them apart from typical white diamonds.

Black diamonds are actually so heavily included with black crystal that they appear to be solid in color. Irradiation is often used to make the black color look solid; a natural black diamond will have a salt and pepper look under magnification.

An oddity in the fancy-colored world is called the Chameleon diamond. These are typically olive green and can temporarily change color to greenish-yellow when exposed to heat or kept in darkness then exposed to light.

With the advent of the lab-grown diamond, owning a fancy colored diamond has become much more affordable. Even the treasured red, blue, and pink colors are available in lab-grown diamonds.
