Exhaustively Analyzed for Superior Quality and Performance

A “Jet Set Type IIA Hearts and Arrows Diamond®” is the most meticulously crafted, exhaustively analyzed and thoroughly reviewed diamond in the world. It starts with the selection of highest quality perfect rough diamond crystals, and world-class skill and attention to detail by master cutters/polishers working with the most sophisticated state-of-the-art technology in ultra-modern facilities.

It takes more skill, more time and more weight loss from the rough to cut diamonds in sweet spot of light performance. Whereas Jet Set Type IIA Diamond® target the very bulls-eye on the dart board, most cutter/polishers actually target the outer most perimeter of the GIA Ex range. Thus doing so they will maximize the yield from the rough while at the same time acquiring the highest grade that GIA awards- but at the expense of cut quality. This difference in approach and philosophy gives rise to a broad range of differences in precision between some GIA Excellent diamonds and a true super ideal diamond as illustrated by the diamond light performance images below.
Concerning the Diamond CUT quality, is the most important of the 4 C’s. CUT has the greatest impact on a diamonds beauty. You may be surprising that of all the diamonds in the market today, only a very small percentage are cut particularly well!  And only a small percentage of those are cut to ideal standards. The truly “exceedingly elite ideal diamonds” are extremely rare. So, how do you distinguish an “exceedingly elite ideal” from an ideal diamond and why does it matter?

The true and full essence of a diamond can only be revealed through the skill and craftsmanship of the craftsman. Only highly skilled Polishing and faceting of a diamond unleashes a diamond’s brilliance and fire. Only highly skilled and Ultra-precise cutting by the most experienced master craftsmen, is key to unlocking the full radiance of a diamond.

Combining The Hearts & Arrows Perfect Cut With an IIA Type Diamond Are The Rarest of All Diamonds
Is Buying a Type IIa Diamond a Smart Investment?

The method which scientifically classifies diamonds according to the level and type of chemical impurities inherent in the diamond is called "Diamond Type". Diamonds are categorized into four types: Type Ia, Type Ib, Type IIa, and Type IIb. These types represent the level of impurities measured at the atomic level, within the crystal lattice of carbon atoms, and require an infrared spectrometer to detect them, unlike the more common inclusions which can be seen by the naked eye or a diamond loupe. Not only is an infrared spectrometer needed to check what type a diamond is, a level of expertise in understanding what one sees when it is examined by an infrared spectrometer. We at CaratsDirect2U.com have the tools and the knowledge to be able to accurately assess the type of diamond and can then appraise them appropriately.
Type IIA Diamonds:

Why is a type IIA diamond a better investment diamond than other diamonds?

Less than 1% of the world's diamonds are Type IIa, also called “Golconda Diamonds”, named for the famous Indian mines that gave the world some of its first truly great diamonds in the 16th and 17th century.). Scientifically speaking, Type IIa diamonds are almost pure carbon diamonds, containing no significant amount of nitrogen in the crystal lattice. Nitrogen is the impurity in diamond that imparts a yellowish hue. The lack of yellow makes for a pure very valuable colorless (D, E or F) color diamond. Type II diamonds are also divided into two categories, Type IIa and Type IIb. These sub-groups are further categorized separated into two groups, Type IIa diamonds which are capable of conducting electricity and Type IIb diamonds which are not able to conduct electricity.

Type IIa diamonds are colorless, unless they have an inclusion or defect in the structure of the diamond that would allow light absorption to occur. Diamonds of this type can be gray- brown, yellow, pink, light blue, or light green (the two last colors arising from radiation exposure.) however, most of the time they are the perfectly colorless diamonds that most people are looking for. This is due to the fact that their structure does not easily absorb short-wave ultraviolet light wavelengths, but instead allows the light to pass through. Such famous diamonds as the Cullinan (the world's largest cut diamond, found in the South African Premier Mine in 1905) and the Koh-i-Noor (Urdu for "Mountain of Light"), which was found in India and now rests in the Tower of London, are type IIa diamonds.

These facts make this diamond type more sought after by the rich and famous, such as the 33.19ct Type IIa “Elizabeth Taylor Diamond” (formerly known as the “Krupp Diamond”) that was purchased in 1968 (before anyone knew that there were different types of diamonds) for $300,000 sold recently at auction for 8.8 million dollars.
Why a Customer Should Choose a Type IIa Diamond (If They Can Afford It)

Type IIa diamonds have many special characteristics both on a “geological” level as well as what can be seen by the eye. This causes them to be more sought after and each one to have a unique story. This also causes them to be more valuable, making them a smart choice for an investment. Most of the types IIa diamonds are larger diamonds, mostly over 10 carats. An increase in size signifies a substantial increase in value and price. On average, a diamond that is certified as type IIa is valued at between 2-3% more than the same diamond that is not certified as type IIa.

For example a 5.50ct D color IF (internally flawless) round cut diamond costs on an average retail website $800,000 while the same diamond if it were Type IIa it would cost around $825,000. Many times the customers who are looking for the highest quality diamonds such as VVS1 or IF clarity, D color, an Excellent or Ideal cut, with no fluorescence, will choose the stone that is Type IIa as in order to own what they perceive to be a more "perfect" diamond.
HEARTS • ARROWS  DIAMONDS
“Jet Set Type IIA Hearts and Arrows Diamonds®”
The term Hearts and Arrows refers specifically to round brilliant diamonds that have been cut to a very high degree of three dimensional symmetry, also referred to as “optical symmetry”. Hearts and Arrows Diamonds will show a distinct pattern of 8 distinct hearts when viewed from the bottom in a special reflector device, and a pattern of 8 arrows when viewed from the top.
It is extremely challenging for the diamond polisher/cutter to attain this level of precision in three dimensions, demanding more skill, more time, and the loss of more weight from the original diamond rough; thereby making it much more costly to produce. Attaining optical symmetry requires an exacting process of making sure all of the tiny facets line up perfectly against their counterparts on the opposite side of the diamond. Only then will a precise pattern of hearts and arrows be present.
