Natural Blue Diamonds

Yes, natural blue diamonds are among the rarest and most valuable colored diamonds in the world. Their rarity is due to the unique geological conditions required for their formation, which include the presence of trace amounts of boron within the diamond's crystal structure.

The deeper and more intense the blue color, the rarer and more valuable the diamond becomes. Because of their scarcity, blue diamonds are highly sought after by collectors and investors.

Blue diamonds come in various types and classifications based on their color, intensity, and characteristics. The Gemological Institute of America (GIA) grades blue diamonds on a scale that ranges from:

• Faint Blue
• Very Light Blue
• Light Blue
• Fancy Light Blue
• Fancy Blue
• Fancy Intense Blue
• Fancy Vivid Blue
• Fancy Deep Blue

Blue diamonds can also have modifying colors that influence their overall appearance. For example, blue diamonds may be described as "Grayish Blue", "Greenish Blue", or "Violet-Blue" when secondary hues or modifiers are present.

Descriptive terminology is often used to convey the distinctive hue of a blue diamond. For example: Sky Blue, Steel Blue, or Turquoise Blue.

The price of blue diamonds can vary significantly based on several factors, including the size, intensity, hue, clarity, and cut quality.

• Larger blue diamonds are exponentially rarer, and their price per carat increases as the size goes up.
• The intensity and purity of a blue diamond plays a significant role in determining their value. Blue diamonds with deeper and more vivid hues, such as Fancy Intense and Fancy Vivid Blue, are much rarer and command higher prices.
• Pure blue diamonds are generally more valuable than those with secondary hues. However, in some cases, blue diamonds with secondary colors, such as gray, green, or violet undertones, can also increase it's value based on the overall visual appeal and rarity of the color.
• While color is the primary factor in pricing blue diamonds, higher clarities can still enhance the value and make it more attractive to prospective buyers.
• The quality of the cut can significantly affect the appearance of a blue diamond, particularly in how it reflects light and presents color. A well-cut blue diamond will maximize the stone's brilliance and color dispersion, making it more desirable.
