Diamonds are precious and the most precious of all diamonds are natural fancy color diamonds.
Fancy colored diamonds come in a variety of shades and colors such as purple, yellow, blue, green, pink and the incredibly rare red. To understand how unbelievably precious and rare these fancy colored diamonds are – out of 10,000 colorless diamonds found, only one will be a fancy color diamond.
Natural Purple Diamond
“A garden of purple is always in bloom!”
Purple diamonds are extremely rare and therefore, the most common question that comes in the mind is whether they exist or not.
And the answer is – yes, purple diamonds are real! They do exist but are extremely rare. Now let’s understand how these colored stones get their stunning hue.
Colorless diamonds are formed through a highly pressured process that involves carbon molecules. Fancy colored stones also go through a similar process. However, it is when other elements find their way inside, a shade begins to form.
The source of the natural color of purple diamonds is quite a mystery and scientists are still not able to ascertain the formation of purple or violet diamond shade. One theory states that it is a combination of boron and hydrogen which is responsible for this vibrant hue.
So, if a stone has only boron imperfections in its anatomical features, it would form a blue color. And the addition of hydrogen forms purple shade in the diamond.
Light purple diamonds have come in lovely shades of lavender, lilac, orchid and mauve colors that create gorgeous purple diamond engagement rings.
Quality of the Purple Diamonds
The quality of the color is the most important factor in determining the value of a fancy purple diamond.
To assess the color, experts take into account hue, tone, saturation, and distribution. The GIA grades for purple diamond are :
- Very Light
- Fancy Light
- Fancy Intense
- Fancy Vivid, Fancy Deep or Fancy Dark
Fancy deep and fancy dark are diamonds with a strong color but do not have saturation (which refers to the intensity of the hue) as much as fancy intense purple and fancy vivid purple diamonds.
Most purple diamond stones contain secondary hues of pink, red, blue, or gray. Depending on the presence of secondary hue, purple diamonds can be divided into two categories :
- Diamonds with secondary hues of pink and red are labeled under ‘Purple’ – example ‘Fancy Purple Pink’ diamond. (Purplish pink diamonds are considered just as valuable as predominantly pink stones.)
- Diamonds with secondary hues of blue and gray are labeled under ‘Violet’ – example ‘Fancy Violet Gray’ diamond.
- Some purple diamonds also exist with orange, red and brown undertones and are valued less.
The presence of secondary hues affects the color of the stone and impacts its price quite significantly. Therefore, the price of a purple diamond varies from stone to stone.
Purple diamonds are more often very light and pastel in tone, even with intense and vivid grades, and violet diamonds are more often deep or dark in tone. They are often modified with pink or brown color.
Since purple diamonds are so rare and precious, a stone with fine color might have eye-visible inclusions but still, be very valuable.
For colorless diamonds, a round brilliant cut is the most favored one as it allows the highest sparkle. However, for purple diamonds, fancy shapes such as cushion cuts and radiant cuts are the most favored ones followed by oval cuts, pear shapes, heart cuts, and marquise cuts.
Why is that so? The reason is that round brilliant cut tends to weaken the color of purple diamonds. And for fancy color diamonds, it is the color which is ultra-unique quality, unlike colorless diamonds where sparkle and brilliance take away the ultimate glory.
- Craftsmen put in their best to enhance the color of the diamond which includes making the girdle thicker, proportions deeper or anything else which will help in highlighting the shade even more.
- Diamond experts recommend a purple diamond in a rose gold setting to accentuate the color’s richness.
- A purple diamond center gem can be contrasted with a colorless diamond halo. The contrast leads to the emphasis on the center purple diamond stone.
- Brownish purple diamonds and grayish violet diamonds (which are more affordable) can also be set in manners to highlight the purple hue of the stone.
Diamond Carat Weight
Carat weight is one of the key factors in assessing the value of a colored diamond.
- Most of the fancy colored diamonds have weight less than 1 carat (regardless of their color).
- Fancy colored diamonds above 5 carats are extremely rare and are highly valued.
- In simple words, the price of a fancy-colored diamond increases exponentially with the carat size.
Engagement Ring Settings for Purple Diamond
Purple is the color that signifies royalty, luxury, magical, power, mystery and nobility, and no doubt it is desired by diamond connoisseur around the world. With their magnificent hue, purple diamonds make for stunning engagement rings.
The style of the engagement ring can intensify or dilute the hue of the purple diamond.
- Side stone setting: Smaller stones can be added to the purple diamond engagement ring which will bring in additional style and of course carat weight.
- Pave setting: Pave setting with smaller stones lining the band of the engagement ring can maximize its brilliance.
- Halo setting: Halo setting around a purple center diamond helps in highlighting the stone and also increases the surface area, which in turn maximizes the ring’s appearance.
Alternatives to a Purple Diamond
The idea of owning a purple diamond is music to the ears, however, the price one has to pay for such luxury can burn a hole in the pocket.
There are some great alternatives to the purple diamond which can give impressive competition to the purple diamond.
Sapphires are beautiful gemstones that are much more affordable than fancy colored diamonds. They come in a variety of shades, from pastel shades that perfectly imitate a fancy purple-colored diamond to more intense shades that are as enchanting as real ones.
Amethyst is another alternative to purple diamonds. Amethyst, a purple shade quartz gem is pretty affordable and available in fine purple shades that can help in making a gorgeous amethyst engagement ring.
Lab-created Alternatives (also known as synthetic, man-made, created and cultured) Diamonds
As the name suggests, lab-created stones are grown or created inside a laboratory. Under specifically controlled conditions, these labs simulate the natural process which creates a natural stone, but for a short period.
These lab-grown stones are similar to natural stones in all aspects except the fact that they are grown in a lab.
Purple diamonds are rare, even for lab-grown diamonds. Purple diamonds begin as pink and grow darker overtime during the growing process.
A lab-created diamond would still be expensive but cheaper than its natural counterpart. Similarly, lab-created sapphire can help you cut down on the price significantly without compromising on the quality.
Treated or Enhanced Stones
A colorless diamond or other gemstone undergoes various treatments to give the stone the desired color. Here, the stones are real, the only difference is that they are colored or their color is enhanced artificially. The only disadvantage of these treated stones is that the color can fade over time with exposure to heat and light.
**An important point to note is that enhanced purple diamonds are difficult to achieve. Enhancement of a thousand carats of blues, greens, oranges, and yellows merely yield two to three carats of purple colored diamonds. Only very few diamonds have the latent ability to turn purple when color enhanced using HPHT (High Pressure, High Temperature) process or when irradiated.
