Ideal Cuts

The Royal Purple Diamond is a 7.34 purple gemstone whose
 origin and history have been largely shrouded in mystery. Due to the rarity of
 purple diamonds, this perfect heart cut stone has been one of the most
 treasured gems ever since it was discovered.&nbsp;The Gemological Institute of America has graded the diamond as a Fancy Vivid stone.

The Royal Purple Diamond holds the distinction as the
 largest purple diamond ever to be discovered. Therefore, you would expect the
 gem to have generated immense publicity during its cutting and faceting stages.
 However, unlike most large and unique diamonds, not much information is
 available on the Royal Purple Diamond. Perhaps it’s that mystery that makes
 gemologists quite interested in this diamond. The diamond is a real work of
 craftsmanship, considering its rare color, large size, and the fancy shape.

Etymology

Two major attributes of the gemstone inspire Royal Purple Heart Diamond. Those include the color and <a href="https://www.petragems.com/education/diamond-shapes/">shape of the diamond</a>.

We already mentioned how difficult it is to come by naturally
 occurring purple diamonds. And we also pointed out how finding large naturally-occurring gem-quality diamonds is even harder. Now, factor in the rare shape
 of the Royal Purple, and you’ll begin to appreciate this gemstone's uniqueness.

Heart shapes are reasonably challenging to cushion. It
 requires high craftsmanship, and cushioning heart shapes means shedding significant
 carats from the stone. So, for the Royal Purple to weigh a whopping 7.34 carats
 after cutting and processing, we can only imagine how heavier it might have
 possibly been as a rough diamond.

Once cushioned, heart shapes are known for their remarkable
 brilliance. Due to their elongated facets, heart-shaped diamonds absorb maximum
 ambient light and color before harnessing it and finally reflecting it back to
 the stone. That explains why the Royal Heart Diamond is one of the most
 sparkling <a href="https://www.petragems.com/blog/gemstones-with-names-pictures-and-colors/">pieces of rare gemstones</a>&nbsp;ever
 discovered.

About The Royal Purple Heart Diamond

Not so much information is available on the history of the
 Royal Purple Heart Diamond. However, unsubstantiated reports claim that the
 diamond might have originated in Russia. After its discovery, the cutting and
 polishing of the Royal Purple were entrusted to Julius Klein Diamond
 Corporation. And that’s as far as the history of the Royal Purple goes.

It’s important to remember that most diamonds are named
 after their owners or mines of origin. But due to the limited information
 available on the history of the Royal Purple, the diamond was exclusively named
 after its color and shape.

However, the Royal Purple Diamond has been handled by some
 of the most renowned entities in the jewelry industry. For instance, it was
 officially graded by the GIA. Besides, the British gemologist Michael Hing also
 had the rare privilege of examining the Royal Purple sometime in 2002. It was one
 of the few famous diamonds Hing ever examined.

Mr. Hing described the Royal Purple Diamond as having a
 diagonal surface graining. According to him, the graining was clearly visible
 to the naked eye, especially if observed under a glancing light. That diamond’s
 external structure flaw is a blemish on the otherwise rare and precious gem.

Mr. Hing added that the stone is not as blue as normally
 depicted in photos. Instead, it’s generally more purple than lilac. The diamond
 also features a thick girdle, though the thickness isn’t uniformly distributed.
 Hing reckons that the extra thickness was an ingenious way of preserving
 the&nbsp;<a href="https://www.petragems.com/education/diamond-carat-weight/">carat weight</a>&nbsp;during
 the cutting and polishing.

Carat

The Royal Purple Heart Diamond weighs a whopping 7.34
 carats, which makes it the largest diamond of its kind.

<a href="https://www.petragems.com/education/diamond-color/">Color</a>

Besides numerous depictions of the Royal Purple as
 lilac-blue, the diamond is purple.

<a href="https://www.petragems.com/education/diamond-cut/">Cut and Shape</a>

The diamond is a perfect heart, a fancy-cut gemstone. It’s
 this combination that gives it its immense glittering effect.

<a href="https://www.petragems.com/education/diamond-clarity/">Clarity</a>

The Royal Purple Diamond has an I-1 clarity—however, diagonal
 surface graining accounts for much of the stone’s external blemishes.

Purple and red diamonds are considered the rarest. And due
 to their exquisite colors, these diamonds come with quite hefty price tags.
 Another thing worth noting is that most purple and red diamonds tend to occur
 in smaller weights, typically below 5 carats. But unlike other rare purple
 diamonds, the Royal Purple Heart Diamond appears to be an exception to that
 rule. The diamond’s 7.34 carats not only give it the distinction of being the
 largest gem-quality purple diamond available. It also means the gemstone is
 quite a spectacle in terms of fire and brilliance. As you may already know, a
 diamond’s light-handling properties improve with an increase in carat weight.

The Royal Purple Heart Diamond is classified under what’s
 known as plastically deformed type IIa diamonds. To better understand this,
 let’s briefly highlight how diamonds occur.

During the formation of diamond crystals underneath the
 earth’s surface, certain other atoms are incorporated into their structures as
 impurities. The two most common ones are Nitrogen and Boron. Nitrogen is the
 most prevalent impurity in diamond crystals, in about 98% of all natural
 diamonds. Diamonds that contain traces of nitrogen tend to appear yellow. Such
 diamonds are known as Type I diamonds. The intensity of the yellow color
 depends on the concentration of nitrogen impurities in the crystal.

The remaining 2% of natural diamonds contain no traces of
 nitrogen and are known as Type II diamonds. However, a tiny percentage {0.1%}
 of Type II diamonds tend to contain considerable amounts of Boron in their
 crystals. Diamonds that contain impurities of Boron generally appear blue and
 are known as Type IIb diamonds. The remaining 99.9% of all Type II diamonds
 contain no impurities, or the quantity cannot be detected. Such diamonds fall
 within Type IIa diamonds and are generally colorless.

However, some Type IIa diamonds may have been subjected to
 plastic deformation of their crystal structures. That often results from the
 bending and twisting the tetrahedral units within the crystal. The deformed
 areas within the crystal can absorb light across various regions of the
 spectrum. As a result, the light is reflected in the stone as rare fancy
 colors. The colors in this category include red, orange, brown, pink, and
 purple.
