Diamonds have long been treasured for their exquisite beauty, but within the realm of these precious gem stones lies a mesmerizing spectrum of colours that adds an extra touch of enchantment. Fancy coloured diamonds, with their captivating hues ranging from soft pastels to vibrant shades, have taken the world of jewellery by storm. In this blog post, we will embark on a journey to discover the various types of fancy coloured diamonds, delve into their grading system, and explore how they compare to their colourless counterparts.

The Dazzling Array of Fancy Coloured Diamonds: Fancy coloured diamonds are an extraordinary rarity, accounting for only a minute fraction of all diamonds mined. They derive their distinctive colours from the presence of trace elements or structural irregularities during their formation. Let's explore some of the most popular types of fancy coloured diamonds:

1. Yellow and Brown Diamonds: The most common fancy coloured diamonds, their warm hues range from light champagne to deep cognac. Yellow diamonds are often graded on the intensity of their colour, with terms like Fancy Light, Fancy, Fancy Intense, and Fancy Vivid.
2. Blue Diamonds: The mesmerizing blue hue of these diamonds is caused by traces of boron. Ranging from pale sky blue to deep oceanic shades, blue diamonds are highly sought after and extremely rare.
3. Pink Diamonds: These captivating gemstones evoke romance and femininity with their delicate pink shades. Pink diamonds are graded based on their hue, tone, and saturation, with Fancy Vivid Pink being the most coveted.
4. Green Diamonds: Infused with a hint of nature's splendour, green diamonds range from light mint to deep forest green. They owe their colour to natural radiation exposure during their formation.
5. Other Colours: Fancy coloured diamonds also come in captivating hues such as red, purple, orange, and even black. Each hue tells a unique story, making every fancy coloured diamond a truly one-of-a-kind treasure.

Grading Fancy Coloured Diamonds: The Gemmological Institute of America (GIA) is the industry authority when it comes to grading coloured diamonds. The GIA assesses fancy coloured diamonds based on three primary criteria: hue, tone, and saturation.

1. Hue: The primary colour of a fancy coloured diamond determines its hue. A diamond's hue can be described as a combination of colours or as a single dominant colour.
2. Tone: The tone refers to how light or dark a coloured diamond appears. The GIA grading scale ranges from Very Light to Very Dark, with variations in between.
3. Saturation: Saturation defines the strength, intensity, and vividness of the colour. Diamonds with higher saturation levels are more vibrant and desirable

Comparing Fancy Coloured Diamonds to Natural Colourless Diamonds: Fancy coloured diamonds possess a unique allure that sets them apart from their colourless counterparts. While colourless diamonds are graded based on their lack of colour, fancy coloured diamonds embrace their vibrant hues as their defining feature. Here are a few points of comparison:

1. Rarity: Fancy coloured diamonds are significantly rarer than colourless diamonds. Their scarcity contributes to their exceptional value and allure.
2. Pricing: The pricing of fancy coloured diamonds varies greatly depending on factors such as hue, intensity, size, and rarity. In general, intense and vivid colours command higher prices.
3. Investment Potential: Both fancy coloured diamonds and colourless diamonds can be excellent investments. However, due to their rarity and growing demand, some fancy coloured diamonds have shown significant price appreciation over time.
4. Personal Expression: Fancy coloured diamonds allow individuals to express their unique personalities and preferences. Their vibrant hues offer endless possibilities for creating bespoke and captivating jewellery pieces.
