Pink Diamonds guide
Pink is one of the rarest naturally occurring diamond colors nature has to offer. Pink diamonds come in a variety of tones from light to vivid pink and frequently have secondary colors such as brown, orange and purple. In today’s market, the demand for Pink Diamonds is high, yet elevated pricing due to their extraordinary rarity may limit many potential shoppers.
The passage of time has only added to the legendary fame, intrigue and mystique of Pink Diamonds. The first pink diamond deposits were discovered in India in the 16th and 17th century and for many years India was the solitary source. A mere 200 years later, new lesser Pink Diamond deposits were found in Brazil and even later in South Africa and the small island of Borneo. Most of these new diamond deposits were light in tone and saturation.
Not until 1979 was there a steady supply of Pink Diamonds with a strong pink hue actively flowing into the market.
This discovery of these gorgeous Vivid Pink Diamonds was made in a remote region of Western Australia near the Argyle Lake. Argyle Pink Diamonds are very rare and greatly desired. In fact, at present they are only auctioned once a year to traders, jewelers and unique collectors. What’s more, they bear a substantial price tag.

Reasoning for the color and diamonds types:
There are few conditions under which Pink Diamonds are formed in nature. One known reason is through the process of geological stress. This occurs after the diamond has already formed. In a process called “plastic deformation”, these diamonds experience an excessive heat and extreme pressure that affects their structure. This effect causes a diamond to receive its pink, purple and brown colors.
Natural pink colored diamonds occur primarily in two types of diamonds:
Ia – The more common type pink diamonds that contain appreciable amounts of nitrogen. This type of diamond covers a wide range of pinks from faint to vivid. With modifiers of purple, brown and orange, they may range in size from 1 pt to 20 CT .
IIa – Relatively nitrogen free, these diamonds often have a “pastel” shade that ranges from faint to intense. They may also have orange or purple modifiers. In addition, they can vary in size from below 1 CT to 100 CT.
The variety of shades and grading:
Pink diamonds come in a wide variety of tones and saturations along with a few secondary hues. In terms of saturation, Pink Diamonds are graded in the standard nine grades from Faint to Fancy Vivid so intense that it actually looks red. The tone grading varies from very light to very dark.
In terms of the color or “Hue” Pink Diamonds appear in the pure form. Although, many do come with a color modifier or “Secondary Hue” such as:
Argyle Pink Diamonds
Have their own color grading system containing more than nine intensity types.
The most famous Pink Diamonds are the Argyle Diamonds which account for only a small percentage of the Argyle Diamond Mine’s entire production of Pink Diamonds. The Argyle Diamonds are unique in their extraordinarily intense Pink color

Pink Diamond Color Categories
Pink diamonds are primarily divided into five color categories:
- Purplish pink
- Brownish pink
- Orangey pink
- Pink Brown
A Pink Diamond with a secondary color will be less expensive than solid one. Only Purplish Pink will be – in rare cases – more expensive than a straight Pink
Pink diamonds with no secondary coloring are the rarest and most expensive of all pink diamonds.
This color of Pink Diamond ranges from:
- A faint pink, resembling a white diamond with just a slight pink hue
- A sweet colored fancy pink
- Vivid Pink, also referred to as a “raspberry pink,”
- Deep, almost reddish pink
The closer to red a Pink Diamond’s coloration is the rarer it is; hence, the more expensive.
A color modifier slightly decreases the value of the diamond. Pink Diamonds with a secondary coloring are more affordable and have a beauty…all their own.
A Pink Diamond with a color modifier is simply an opportunity for more people to own a fancy color diamond.
