A Guide to 10 Different Colors of Diamonds

The Background of Diamonds Explained

Diamonds are formed deep within the Earth’s mantle under extreme pressure and heat, around
100 miles below the surface. These conditions cause carbon atoms to crystallise into the
stunning gemstones we know. Brought to the surface through volcanic eruptions, diamonds are
mined from volcanic pipes known as kimberlite or lamproite.

Historically, diamonds were first discovered and mined in India over 2,000 years ago, and later,
significant deposits were found in Brazil and South Africa. Beyond their natural formation,
diamonds have been prized for their beauty, rarity, and hardness, symbolising wealth and status
throughout history.

Top 10 Different Colors of Diamonds

In this section, we will uncover the different types of diamonds so you can differentiate them
from each other:

White Diamonds

White diamonds, also known as colourless diamonds, are the most common and traditional
type. They are graded on a scale from D (completely colourless) to Z (light yellow or brown).
The closer a diamond is to being colourless, the more valuable it typically is. White diamonds
are prized for their dazzling brilliance and are the most popular choice for engagement rings.

Yellow Diamonds

Yellow diamonds, often referred to as “canary diamonds” when they exhibit a deep, vibrant
yellow hue, are the most common type of coloured diamonds. The yellow colour is caused by
the presence of nitrogen during the diamond’s formation. These diamonds range from faint
yellow to vivid canary, with more intense colours being rarer and more valuable.

Blue Diamonds

Blue diamonds are rare and highly sought after. Their blue hue comes from traces of boron
within the diamond’s structure. The most famous blue diamond is the Hope Diamond, which has
a deep, captivating blue colour. These diamonds can range from a faint blue to a rich, deep
blue, with deeper colours being more valuable.

Pink Diamonds

Pink diamonds are among the rarest and most desirable diamonds. Their pink hue can range
from very light to deep, intense pink. The exact cause of the pink colour is still debated among
scientists, but it is generally believed to be due to a distortion in the diamond’s crystal lattice
structure. Pink diamonds are often associated with romance and femininity, making them a
popular choice for special jewellery pieces.

Green Diamonds

Green diamonds are extremely rare and unique. Their green colour is usually caused by
exposure to radiation during the diamond’s formation, which displaces carbon atoms and
creates a green hue. The colour can vary from a faint green to a rich, deep shade. Pure green
diamonds are incredibly rare, making them highly valuable.

Red Diamonds

Red diamonds are the rarest of all coloured diamonds. They are so rare that fewer than 30 true
red diamonds are believed to exist worldwide. The exact cause of their red colour is not fully
understood but is thought to be due to a unique deformation in the crystal lattice structure. Red
diamonds are incredibly valuable, with prices often reaching millions of pounds per carat.

Orange Diamonds

Orange diamonds, sometimes called “fire diamonds,” exhibit a warm, vibrant orange hue. This
colour is due to the presence of nitrogen, similar to yellow diamonds, but in a different structural
arrangement. The intensity of the orange colour can vary, with more vivid oranges being rarer
and more valuable. These diamonds are unique and eye-catching, making them a favourite for
those looking for something different.

Purple Diamonds

Purple diamonds are rare and beautiful, ranging in colour from light lavender to deep purple.
The exact cause of the purple hue is not entirely clear but is thought to be due to the presence
of hydrogen. These diamonds are highly sought after for their unique colour, with more intense
purple shades being particularly prized.

Brown Diamonds

Brown diamonds, also known as “chocolate diamonds” or “cognac diamonds,” are more
common than other coloured diamonds. They are characterised by a warm brown hue, which
can range from light to dark shades. These diamonds have gained popularity in recent years,
especially for use in more affordable and distinctive jewellery designs.

Black Diamonds

Black diamonds, also known as “carbonado,” are distinct for their opaque black appearance.
Unlike other diamonds, which derive their colour from impurities, black diamonds owe their
colour to numerous inclusions and graphite. They are not typically as sparkly as other diamonds
but are favoured for their unique, bold look. Black diamonds are often used in fashion-forward
jewellery pieces and make a striking statement.
