Natural Color Purple Diamonds

Color diamonds (often called fancy color diamonds) are natural diamonds that show a distinct body color outside the traditional colorless range. That color forms through natural geological conditions such as trace elements, lattice distortion, or other structural characteristics during formation.

Yes. A natural purple diamond is a genuine diamond with naturally occurring color. The key distinction is natural vs. treated. If a stone has been artificially enhanced (for example, through irradiation or other methods), it must be disclosed as treated. However, at Langerman we deal exclusively with natural color diamonds. 

Purple color can appear when lattice characteristics and trace influences alter light absorption, producing a visible purple hue. In practice, purple diamonds can also show secondary colors (also known as modifying colors) such as pink, gray, or brown, which affects both face-up appearance and price. That’s why two diamonds with the same carat weight can look and feel very different in person.

Purple diamond pricing is still based on the 4Cs, but color leads. In most cases:

• Color: Stronger, purer purple with higher saturation commands a premium
• Carat: Prices rise quickly as size increases because supply drops off sharply
• Clarity: Eye-clean often matters more than “perfect” clarity, depending on the setting
• Cut: Well-proportioned cuts improve brightness and help distribute color evenly

Purple diamonds are found in a small number of diamond-producing regions worldwide. Origin can influence availability, typical modifiers, and the sizes that appear on the market.

Purple diamonds are typically found in regions known for their rich deposits of color diamonds, particularly in the mineral-rich landscapes of Australia and South Africa.

Purple diamonds from Australia often feature unique overtones and remarkable clarity, reflecting the varied conditions of their formation.

The intense hues of South African purple diamonds result from specific geological conditions unique to this region, rather than being spread across the continent.

​​Langerman offers a stunning collection of purple diamonds for sale, including shades like Violet, Indigo, and Lilac. Each shade represents a different aspect of purple, ranging from the deep and mysterious indigo to the soft and romantic lilac.

• Violet Purple Diamonds. These diamonds feature a deep, rich purple that is both bold and beautiful.

• Lilac Purple Diamonds. These showcase a lighter, more delicate purple, perfect for those who prefer a subtler touch of color.

For engagement rings, prioritize face-up color and evenness, durability through cut and setting choice (especially protecting corners on square and fancy shapes), and an the assurance that the diamond is natural, which is particularly important when you’re searching for a “real purple diamond.”
