Understanding Fancy Coloured Diamonds

Fancy coloured diamonds are gems that are not colourless or white. Their value is determined by the intensity and distribution of their colour, such as:

• Pink
• Blue
• Yellow

Apart from their eye-catching appearance, coloured diamonds also carry symbolic meanings, with blue diamonds associated with calmness and serenity, and pink diamonds symbolising love and creativity.

These alluring gemstones come in a spectrum of colours, with each hue having its unique origin. For instance, the yellow colour in yellow diamonds is caused by the presence of nitrogen, while the blue hue in blue diamonds results from the presence of boron.

With so much variety and rarity, coloured diamonds, also known as fancy diamonds, offer endless possibilities for creating a truly one-of-a-kind jewellery piece.

Grading Coloured Diamonds

When it comes to grading coloured diamonds, the primary focus is on the hue, saturation, tone, and colour intensity of the stone. Unlike colourless diamonds, where the cut, clarity, and carat weight take precedence, coloured diamonds are valued for the strength and distribution of their colour. The most sought-after grades for coloured diamonds are intense and vibrant, with these stones exhibiting the deepest and most saturated hues.

Grasping the grading system for coloured diamonds is vital when choosing a stone since the colour significantly influences its worth. For example, a diamond graded as ‘Fancy Vivid’ implies a relatively lighter tone with the strongest possible saturation, while a diamond with the darkest tone and some colour saturation is generally labelled as ‘Fancy Deep’. Gaining knowledge of the grading system for coloured diamonds aids you in making a wise decision when picking the ideal gem for your jewellery.

Understanding the Grading Scale for Coloured Diamonds

1. Faint
   • Description: Diamonds with this grade have a slight trace of colour. This colour is often so light that it's hard to detect unless compared side-by-side with diamonds of a higher grade.
   • Usage: Often used in jewellery where the faint colour is complemented by other stronger-coloured gems.
2. Very Light
   • Description: These diamonds show a more noticeable hint of colour, but it's still quite subtle.
   • Usage: They're perfect for those who want just a whisper of colour in their diamond jewellery.
3. Light
   • Description: The colour in light diamonds is clearer than the very light ones, but it’s not yet at its full potential.
   • Usage: Ideal for those who appreciate a hint of colour but don't want it to overshadow the overall appearance of the jewellery.
4. Fancy Light
   • Description: This is where the diamond's colour starts to stand out more prominently, yet remains in a lighter shade.
   • Usage: For those seeking a balanced blend of sparkle and colour.
5. Fancy
   • Description: A middle point in the grading system, "Fancy" diamonds have a distinct colour, which is neither too light nor too intense.
   • Usage: They're often chosen by individuals who desire a noticeable colour without it being overly dominant.
6. Fancy Intense
   • Description: As the name suggests, these diamonds have a vibrant and intense colour that is hard to miss.
   • Usage: Perfect for statement pieces and those who want their diamonds to catch eyes with their rich colour.

   • Usage: These are premium diamonds often used in high-end jewellery pieces and are highly coveted by collectors.
8. Fancy Dark
   • Description: Fancy dark diamonds have a tone that is deeper than the vivid ones but lacks the same intensity. The resulting shade is more muted but rich.
   • Usage: Ideal for vintage-inspired pieces or jewellery that seeks to evoke a sense of depth and mystery.

Diamond Colours

Yellow Diamonds

Yellow diamonds, the most prevalent type of coloured diamond, are known for their eye-catching hues and symbolic significance. Often associated with self-confidence, creativity, and clarity of thought, yellow diamonds are believed to promote joy and prosperity. These stunning gemstones come in various shades, ranging from canary yellow to brownish-yellow, greenish-yellow, and orange-yellow.

The unique yellow colour in these diamonds is derived from the presence of nitrogen in their crystalline structure. In choosing a yellow diamond, its hue and colour intensity should be taken into account as they greatly influence the stone’s value.

Pink Diamonds

Pink diamonds, with their delicate hues and enchanting beauty, are among the rarest and most valuable fancy coloured diamonds. These gems are believed to symbolise.

• creativity
• femininity
• love
• romance

This makes pink diamonds a popular choice for engagement rings and other sentimental jewellery pieces.

The origin of the pink hue in pink diamonds remains somewhat of a geological mystery, with experts believing that the pressure experienced during their formation is what causes the colour. The shades observed in pink lab grown diamonds may be attributed to distortions in the crystal lattice that occur during formation, resulting in a diverse range of saturations. The Pink colour is often enhanced by using post-growth treatments such as irradiation and annealing

Due to their rareness and charming beauty, pink diamonds have become a desirable gemstone for individuals aiming to create a genuinely remarkable impression.

Blue diamonds have their hues typically ranging from pale to deep blue, with the Hope Diamond being a famous version of the latter. Although their colour intensity is not as broad as that of other coloured diamonds, blue diamonds still offer an exquisite and serene alternative for those seeking a unique and meaningful gemstone.

Green Diamonds

Green lab grown diamonds, with their mysterious origins and vibrant hues, embody the essence of life and promote youth, vitality, and balance. The colour in green diamonds is typically achieved through post-growth irradiation treatments or by incorporating specific trace elements during the growth process.

Sporadically discovered in various locations around the world, green diamonds are a symbol of loving and healthy relationships. With their mesmerising hues and intriguing formation process, green diamonds make a captivating addition to any jewellery collection, offering a refreshing and lively alternative to traditional gemstones.

Purple Diamonds

Regal and majestic, purple diamonds are a symbol of nobility, luxury, and universal connections. The presence of hydrogen and boron within the diamond imparts an enchanting purple hue, making these gemstones a rare and highly sought-after treasure.

Their rarity is further emphasised by their typically small size and limited range of vivid saturations. With their rich symbolism and breathtaking beauty, purple diamonds make a striking statement in any jewellery piece, evoking a sense of elegance and sophistication that is truly unparalleled.

Orange Diamonds

Vibrant and bold, orange diamonds inspire a sense of energy, creativity, and success in relationships. The unique colour of these gemstones is a result of the presence of nitrogen and structural deformities within the diamond’s crystal lattice.

Bright orange diamonds are exceedingly uncommon, while those with additional hues are more frequently found. The distinctive colour of these diamonds is attributed to nitrogen, much like it is for yellow diamonds. Their shades span from vibrant orange to mellow amber,  often earning them the nickname "fire diamonds." The stronger the hue, the more scarce the diamond usually is. Diamonds with less than 25% orange hue are categorised as 'Orangy' diamonds.

Orange diamonds are relatively rare and offer a unique alternative for those seeking a daring and audacious gemstone. Some characteristics of orange diamonds include:

• Vibrant and captivating charm
• Unique and rare
• Exude warmth and energy reminiscent of a sunset.

Red Diamonds

Red diamonds are symbols of passion and intense love. Their mesmerising hue is attributed to a rare deformation in the atomic structure, similar to that of colourless diamonds. As the ultimate expression of ardour and devotion, red diamonds make a truly unforgettable statement in any piece of jewellery.

These incredibly rare gemstones are highly sought after for their striking beauty and captivating symbolism. In choosing a red diamond, its rarity, value and the exceptional story behind its formation should be taken into account. With their unparalleled allure and fiery passion, red diamonds are truly one of the most enchanting of all coloured gemstones.

Black Diamonds

Black diamonds, with their distinctive grey or white inclusions, are a unique and unconventional choice for those seeking a gemstone that exudes strength and inner power. These captivating stones are believed to confer the capacity to confront any hardships upon the wearer. They are thought to symbolise faith in a relationship and the potential of the relationship to overcome any impediments.

While relatively rare and expensive, black diamonds offer a striking alternative to other coloured gemstones, with their opacity, high lustre, and internal inclusions setting them apart from the rest. For those looking to make a bold and powerful statement, black diamonds are the perfect choice, embodying a sense of strength, power, and protection like no other gemstone.

Terminology

In the world of coloured diamonds, understanding the terminology used to describe these unique gemstones is essential in selecting the perfect stone. The following terms are used to describe the appearance of fancy coloured diamonds:

1. Hue
   • Description: At its core, hue refers to the primary colour of the diamond. It's the first impression of the colour that one perceives. For example, blue, green, yellow, and red are all hues. In fancy coloured diamonds, it's possible to have secondary or even tertiary hues that contribute to the overall appearance of the stone.
   • Significance: Identifying the primary hue is crucial as it is often the starting point in determining the diamond's overall appeal and value.
2. Saturation

   • Significance: Saturation plays a pivotal role in determining a diamond's grade. Diamonds with higher saturation levels, like those graded as "Fancy Vivid", are often more valuable and sought-after.
3. Tone
   • Description: Tone pertains to the lightness or darkness of a hue. It's the relative amount of light or darkness present in the diamond. A diamond can have a light tone, making the colour appear pale, or a dark tone, leading to a deeper shade.
   • Significance: Tone provides depth and dimension to the diamond's colour. Understanding the desired tone can guide purchasers in selecting a diamond that aligns with their aesthetic preference, be it a light pastel shade or a deep, moody colour.
4. Colour Strength
   • Description: Colour strength encompasses the overall prominence of the colour in the diamond. It's a combination of the saturation and tone, reflecting how potent the colour appears in the diamond. A diamond with strong colour strength will showcase its hue vibrantly and distinctly.
   • Significance: Colour strength is vital in determining the diamond's visual impact. Diamonds with significant colour strength often become statement pieces, drawing attention and admiration.

These terms help define the diamond’s characteristic colour and play a significant role in determining its value.

Some common terms you may encounter when discussing coloured diamonds include:

• Colour (light yellow, dark yellow, etc.)
• Vivid (intensely saturated colour)
