Diamonds are one of the most coveted gems in the world, and colored diamonds are even more so. While diamonds come in a variety of colors, purple diamonds are among the rarest and most valuable. These diamonds get their unique color from the presence of trace amounts of hydrogen in the crystal lattice. In this blog post, we'll explore the unique features of purple diamonds, from their formation to their grading and care.

How Purple Diamonds Are Formed

Like all diamonds, purple diamonds are formed deep within the Earth's mantle under immense heat and pressure. However, the conditions required to create purple diamonds are unique. Unlike other colored diamonds, which get their color from the presence of other trace elements, purple diamonds get their color from hydrogen.

The hydrogen in purple diamonds is thought to have been present when the diamond was first formed, and it becomes trapped within the diamond's crystal lattice. As a result, purple diamonds have a unique hue that ranges from a faint lavender to a deep violet.

The geological conditions required to create purple diamonds are also unique. These diamonds are typically found in regions with high levels of seismic activity, such as Australia and Siberia. In these regions, diamonds are brought to the surface through volcanic eruptions and are then mined for their unique color and rarity.

Grading Purple Diamonds

When it comes to grading purple diamonds, color is king. The Gemological Institute of America (GIA) grades colored diamonds on a scale that ranges from faint to fancy deep, with fancy vivid being the most valuable. However, when it comes to purple diamonds, even the faintest hue can be valuable due to their rarity.

In addition to color, the other Cs of diamond grading - clarity, cut, and carat weight - also play a role in determining the value of a purple diamond. However, color is the most important factor, and a diamond with a lower carat weight but a more vivid color can be more valuable than a larger diamond with a less intense hue.

The value of a purple diamond is also influenced by the presence of secondary hues. For example, a purple diamond with a secondary pink hue can be more valuable than one with a secondary gray hue. This is because pink is a highly sought-after hue for colored diamonds.

Famous Purple Diamonds

Purple diamonds are so rare that there are few famous examples of these gems. One of the most famous purple diamonds is the Royal Purple Heart diamond, which was given to the United States Military in 1944. This diamond has a deep purple hue and is believed to be worth millions of dollars.

Another famous purple diamond is the Supreme Purple Star, which was discovered in 2002 in the Marange region of Zimbabwe. This diamond is a vivid purple-pink hue and weighs 15.4 carats. It is believed to be worth around $4 million.

Buying Purple Diamonds

If you're interested in buying a purple diamond, it's important to work with a reputable jeweler who has experience with colored diamonds. The rarity and value of purple diamonds mean that there are many imitations and treated diamonds on the market, so it's essential to work with someone you trust.

When choosing a purple diamond, look for one with a unique hue and minimal secondary hues. The color saturation should be even throughout the diamond, with no visible color zoning. The diamond should also have good clarity and a well-proportioned cut.

Caring for Purple Diamonds

Caring for a purple diamond is similar to caring for any other diamond, but there are some unique considerations to keep in mind. One of the most important is to protect the diamond's color. Avoid exposing the diamond to extreme heat or light, as this can cause the color to fade or change. Additionally, avoid exposing the diamond to chemicals or abrasive materials that can scratch or damage the surface.

To clean a purple diamond, use a soft-bristled brush and mild soap and water. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the diamond's surface. It's also a good idea to have the diamond professionally cleaned and inspected periodically to ensure that it remains in good condition.

Conclusion

Purple diamonds are rare and unique gemstones that offer exceptional beauty and investment potential. From their formation under unique geological conditions to their grading and care considerations, purple diamonds have a set of features that make them stand out from other colored diamonds. If you're interested in owning a purple diamond, be sure to work with a reputable jeweler who can help you find the perfect gemstone that meets your specific requirements. With proper care, a purple diamond can remain a cherished piece of jewelry for generations to come.
