Bottom Line Recommendation

Look for purple diamonds from a vendor with high-quality photos, like James Allen or Leibish & Co. Color can vary significantly even within a specific color grade, and you want to make sure you’re getting top quality for the price you’re paying. In our experience, Leibish & Co. offers the best prices and overall customer experience in the Fancy Color Diamond market—and provides the highest level of expertise in enhancing the color of the stone when set in jewelry.

Origin of Purple Diamond’s Color

Similar to other Fancy Color Diamonds, an impurity likely exists in the composition of purple diamonds. While there’s not a consensus on the cause of the purple gem’s hue, large amounts of hydrogen and boron are present within the stone. The particular way these elements interact within the crystal probably plays a role in forming its distinct purple shade. Some gemologists also believe that pressure endured during the purple diamond’s voyage to the Earth’s mantle has influenced the stone’s hue.

When searching for a purple diamond, look for one that’s not color treated. If you’re unsure how to differentiate between a “pure” stone and a color-treated one, reach out to a professional.

Purple Diamond’s Intensity Levels

Purple diamonds appear in several color intensity levels and follow the GIA grading scale for Fancy Diamonds. As the richness and saturation of a purple diamond increases so does its color grade.

The GIA grading scale is as follows:

  • Faint
  • Very Light
  • Light
  • Fancy Light
  • Fancy
  • Fancy Intense
  • Fancy Vivid, Fancy Deep, or Fancy Dark

In addition to predominantly purple stones, many purple diamonds contain a secondary color or overtone. The most common secondary colors are pink, pinkish and grayish. Some purple stones also exist with red and brown overtone colors.

Secondary colors usually detract from the overall beauty and value of a diamond—with the exception of a purplish pink stone. Purplish pink diamonds are considered just as valuable as predominantly pink stones, like this 0.79 Carat intense pink purple diamond.

Color enhanced purple diamonds will often display a higher saturation and an orange fluorescence. If you’re unsure if a diamond is color-treated or natural, contact one of our experts for a professional opinion.

Purple Diamond’s Rarity and Prices

While purple diamonds are not as rare as other color diamonds like red, pink or blue, a pure purple diamond is quite hard to come by. The majority of purple diamonds are found with overtone colors. Very rarely do our customers buy a purple diamond with no overtone.

Purple stones with a modifying color like pink are less expensive than a “pure” purple. For example, this 0.42 Carat Fancy Pink Purple Diamond Round Cut is priced at $15,210 and this 0.40 Carat Fancy Deep Pinkish Purple Cushion Cut is priced at $38,100.

Though it’s challenging to find a “pure” purple diamond on the market, on a rare occasion you can snag one from a top vendor like Leibish & Co. Overall, expect the price to be quite high on a predominantly purple diamond, and even for many with a secondary tone.

Purple Diamond Engagement Ring Settings

A purple diamond will likely turn heads, no matter what ring setting it’s in. Here, we provide you some inspiration for various styles available. Note that the rings include stones of other colors, proving once again how rare a purple diamond is.

Style 1: Side stone setting

Adding smaller stones to your purple diamond engagement ring will offer additional carat weight and style.

Side stone setting example: Purple Radiant Center with Yellow Radiant Side Stones

Style 2: Pavé setting

Maximize the brilliance of your engagement ring with a pavé setting, inclusive of smaller stones lining the band.

Pavé setting example: Argyle Twin Pinkish Purple Pear Shape Diamond Ring

Style 3: Halo setting

Consider a halo setting to surround a stunning purple stone. You’ll increase the surface area of your ring and highlight your center diamond.

Halo setting example: Fancy Pink Purple Cushion Millprong Halo

Popular Jewelry Settings for Purple Diamonds

Purple diamond jewelry will likely last for generations. Choose a pendant or set of earrings for your rare and unique stone.
