Differences Between Natural Fancy Colour Diamonds and Treated Colour Diamonds

Natural fancy color diamonds and treated color diamonds are two distinct categories of colored diamonds. Here are 10 key differences between them:

Origin: Natural fancy color diamonds are formed deep within the Earth’s crust over millions of years through natural geological processes. On the other hand, treated color diamonds are natural diamonds that undergo various treatments to enhance or alter their color.

Color Formation: Natural fancy color diamonds acquire their colors due to the presence of trace elements or structural defects during their formation. Treated color diamonds, on the other hand, have their colors altered through artificial methods such as irradiation or high-pressure high-temperature (HPHT) treatments.

Rarity: Natural diamonds with fancy colors are exceedingly uncommon, comprising a minor proportion among all extracted diamonds. Treated color diamonds, however, are more common as they can be created from lower-grade or less desirable natural diamonds.

Value: Natural fancy color diamonds are highly valued due to their rarity and unique colors. They often command higher prices compared to treated color diamonds, which are generally less expensive.

Permanence of Color: The color in natural fancy color diamonds is permanent and will not fade or change over time. In treated color diamonds, the altered color may be stable but can sometimes fade or change with prolonged exposure to certain conditions.

Certification: Natural fancy color diamonds are certified by reputable gemological laboratories to confirm their natural origin and determine the intensity and quality of their color. Treated color diamonds also undergo certification but are typically disclosed as “treated” on their grading reports.

Color Range: Natural fancy color diamonds exhibit a wide range of hues, including yellow, brown, pink, blue, green, purple, and red. Treated color diamonds can also display a variety of colors but may be limited to specific shades or hues achievable through treatment methods.

Uniqueness: Each natural fancy color diamond is unique, with its own distinct color pattern and characteristics. Treated color diamonds, while still unique in their own right, may have more similarities in appearance due to the treatment process

Market Demand: Natural fancy color diamonds have a strong market demand among collectors, investors, and jewelry enthusiasts seeking rare and exclusive gemstones. Treated color diamonds are often sought after by buyers looking for more affordable colored diamond options.
