Play With a Full Spectrum of Colors - In Diamonds

Play With a Full Spectrum of Colors - In Diamonds
"Color is the place where our brain and the universe meet."
Paul Klee

You don’t need to be a fine artist, gemologist, or fashion designer to love colors. But to truly appreciate the incredible spectrum of natural colored diamonds, it helps to have a basic understanding of color. 

Color Systems

Invented in the 19th century, the traditional RGB model features the primary colors red, yellow, and blue, and complementary colors green, purple, and orange. The Munsell color system, an early 20th century scientific approach based on human’s response to color, was elected in 1995 as the basis to enhance GIA’s International Diamond Grading System™.

Playing with the Color Wheel

Looking at the color wheel will help you pair colors that play off each other. Saturation is the expression of the bandwidth of color, which results in varying intensities of the same color. Monochromatic color schemes play off variations in lightness and saturation of the same color to create elegant visual effects. A good example of this would be an eternity ring with different shades of yellow diamonds.

In the RGB model, complementary color pairs opposite each other on the color wheel are red–green, yellow–purple, and blue–orange. When you use these colors in the same piece, it can create quite a dramatic statement. 



Using analogous colors next to one another on the color wheel is a great way to mix and match shades and tones in the same color scheme. This is similar to a monochromatic color scheme but results in a richer, nuanced look. One approach for playing with analogous colors is to set the same saturation of pink and blue diamonds or orange and yellow diamonds in one piece.


The triadic color scheme using three colors equally spaced around the color wheel results in a strong visual statement and rich color combinations. In jewelry, you can achieve a harmonious, more balanced look by positioning subtle hues of triadic colors next to each other, as in this purple and lime diamond ring  in which the yellow gold setting is the third color. 


Tetradic color harmony (also called double complementary) is the richest color scheme because it uses four colors arranged in two complementary color pairs. Although this is a challenging color theory to put into practice, choosing one color to dominate with subtle hues of other colors is a good technique for achieving striking harmony.


Setting white diamonds as a halo or sidestones next to color diamonds enhances the color. You can also play with a black and white scheme, as in this white and black diamond ring. Here are a few other pieces with stunning color combinations that embody best practices in color theory.

Step into the mesmerizing world of natural Pink diamonds, synonymous of elegance and sophistication. These exquisite gems have stolen the spotlight in the realm of fine jewelry, captivating the hearts of fashion enthusiasts around the globe. 

In this article, we’ll explore the enchanting features of Fancy Pink diamonds, uncovering their origins, possible tones, and the growing fascination around them. As we delve into their unique characteristics, you’ll learn how they compare to other popular pink gemstones, revealing the distinct advantages that set them apart.

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.

Rarity And A Growing Fascination

The allure of these unique stones lies not only in their enchanting beauty but also in their rarity.

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. With the recent closure of the renowned Argyle mine in Australia, a significant source of Pink diamonds, their scarcity has skyrocketed.

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.
