A Brief Introduction to Color Diamond History


Since antiquity to the 20th century, a wide range of color diamonds was discovered. Blue, soft pinks, reds, yellows and browns, gray, olive, and purple. From Brazil to India, and from Russia to Australia, natural color diamonds have been found in mines worldwide. These colorful stones captivated royals, maharajas, and aristocrats for centuries. There are even records of a diamond’s caste system in India: Depending on the person’s rank, they were allowed to own certain shades of color diamonds. 

In the French court of King Charles VII, noblewoman Agnès Sorel became a trendsetter after wearing a 5-carat pink diamond ring--a gift from the monarch who had just made her his official mistress. Natural color diamonds have been revered as symbols of beauty and power for women ever since then. 

This changed in 1948 when a clever marketing campaign promoting colorless diamonds in engagement rings became widely successful. “Diamonds are forever,” the ad read. And the rest was history. Every woman wanted colorless diamonds, so jewelers and designers acted on and followed with the increased demand. Everybody in the diamond industry wanted to trade, collect and work with colorless diamonds almost exclusively. Resulting in natural color diamonds being temporarily forgotten, only to resurface in Antwerp after the 1960s. Among a few other visionary collectors, Arthur Langerman helped shine a light back to color diamonds, their value, and their unique attributes. 

Talking About Color Diamonds in Natural Terms

Being able to describe diamond colors naturally has been our founder Arthur Langerman’s mission since he started collecting and polishing the gems six decades ago. The Gemological Institute of America (GIA) offers a chart identifying different hues as a guide for describing color diamonds. This wheel aims to organize fancy colors by hue, tone, and saturation. But, although helpful for the trade, the phrase “fancy intense purplish-pink” doesn’t really connect with consumers to express the particular shade this name refers to. 

This system also limits the spectrum to only 27 hues being described in a combination of seven words. In the luxurious world of fine jewelry, desire and emotion play an essential part. Evocative names that help visualize colors and suggest comparisons with familiar objects help awaken a color’s emotion in people’s brains. Think about a Canary diamond or an Olive diamond; these names call for very specific shades of yellow and green, respectively.

You’ll find over 150 diamond shades and their intuitive descriptive names within the first pages of Rapaport’s October 2021 Special Supplement.

In this article, we’ll explore the enchanting features of Fancy Pink diamonds, uncovering their origins, possible tones, and the growing fascination around them.

The Origin Of Their Mesmerising Hues

Fancy Pink diamonds are the result of a remarkable geological process that lasted millions of years. During their formation process, atomic traces of minerals such as hydrogen, nitrogen, or boron were introduced into their crystalline structure, resulting in impressive hues.

However, another scientific theory states that the pink hue comes from a deformation in the crystal lattice of the stone, a phenomenon caused by extreme pressure.

Whichever the cause, thanks to our Earth’s natural transformations, today we get to enjoy the exceptional shades of Pink diamonds.

As luxury enthusiasts and jewelry connoisseurs seek to come in possession of the most exclusive and coveted pieces, the interest surrounding fancy pink diamonds continues to grow.

Pink Diamond’s Unparalleled Properties

The refractive index of a diamond is approximately 2.42. This high refractive index is one of the factors that contribute to the exceptional brilliance and sparkle that diamonds are renowned for. The high refractive index allows diamonds to bend and reflect light in a way that creates maximum dispersion and brilliance, resulting in their captivating play of light and fire. It is this unique optical property that sets diamonds apart from other gemstones and contributes to their timeless allure and desirability.

Diamonds are renowned for their exceptional hardness, ranking 10 on the Mohs scale, which is the highest possible rating. This remarkable property makes diamonds highly resistant to scratching and abrasion, ensuring their longevity and durability even with daily wear.

The hardness of a diamond contributes significantly to its value. Diamonds are prized for their ability to withstand the rigors of everyday use without losing their beauty or succumbing to damage. This durability ensures that diamond jewelry, such as engagement rings and heavily worn pieces, can be cherished forever and passed down through generations.

What About Other Pink Gemstones?


This pink gemstone is often used in jewelry for its vibrant color. Pink tourmaline can be found in various parts of the world, including Brazil, Afghanistan, Mozambique, and the United States. Each location may produce unique variations in color and quality, making it more complicated for the regular customer to understand how to measure and compare characteristics.

Tourmaline ranks 7 to 7.5 on the Mohs' scale of hardness, making it moderately durable, but relatively softer compared to Pink diamonds. With a refractive index between 1.624 and 1.644, pink tourmaline exhibits a good amount of brilliance and light dispersion.

Pink quartz

This mineral showcases a soft, delicate pink hue that does not typically offer much sparkle. There are multiple levels of transparency available, from very translucent to milky opaque or smoky with yellow or brown undertones.

Scoring a 7 on the Mohs scale, pink quartz is relatively durable and suitable for some types of jewelry. However, it is still important to protect it from impact, and best suitable for earrings and low-wear pieces.

Pink Sapphire

The intensity of its color depends on the place of origin and the combination of trace elements present within its crystal structure.

With a hardness of 9 on the Mohs scale, pink sapphires are very durable and resistant, making them suitable for all kinds of jewelry pieces. However, they are more prone to scratches than diamonds.


Kunzite is quite affordable because it’s relatively unknown although it can be found in many places like Afghanistan, Brazil, Madagascar, and the USA.

Like most color stones, kunzite can be undergo irradiation or heat treatments to enhance its color. Exposure to heat and bright light can cause color in both natural and treated kunzite to fade over time.


Most morganite deposits are found in Brazil, but the highest quality specimens come from Madagascar. Typically, morganite enjoys a high transparency with minimal inclusions resulting in clear, polished stones.

Scoring a 7.5 to 8 on the Mohs scale, Morganite is safe and durable enough for jewelry.

Your Best Choice: Pink Diamonds

There are multiple options to choose from to create a jewel with pink gemstones. However, they all fall short when compared to the durability and brilliance of natural Pink diamonds. With sources becoming more scarce while demand continues grows, Pink diamonds keep appreciating in value making them a better financial choice when compared to other gemstones which tend to loose value in the resale marker. Pink diamonds present multiple advantages for their investment potential and as a valuable asset to be passed on for generations.

When purchasing color gemstones, it’s important the buyer requests a professional laboratory report that discloses any enhancements to make an informed decision. Unfortunately for most consumers, it’s hard to find full-detailed information on a finished jewelry piece and it requires additional effort and inquiries to confirm the quality of a gemstone.
