Green Diamonds | Schwanke-Kasten Jewelers

Gemologists rank green diamonds as among the most rare of the naturally colored diamonds. These marvelously beautiful and unique diamonds have been exposed to cosmic radiation over its million year formation. Other colored diamonds tend to have an additional element such as hydrogen as an inclusion. Please note, holding a green diamond will not make your finger fall off as the radioactive half-life has long since passed by the time it has been found. Diamonds with the natural colors of green, blue or red account for less that 0.07% of all diamonds examined by the GIA.

Green Diamond Formation

As we mentioned before, green diamonds form due to radioactive materials being present during its formation. Moreover, these materials could be uranium or thorium. Geologist have concluded that radiation penetrates the diamond crystal and can knock electrons or carbon atoms out of the specific crystal lattice. This often appears as a shallow “green” skin on the outside of the diamond, but uniform green throughout the diamond can exist although it is much rarer.

Furthermore, because electrons and carbon atoms are displaced in the crystal lattice, the way light enters and is refracted is affected. Hence the green portion of the visible color spectrum is reflected while the rest are absorbed and gives the diamond that appearance.

Additionally, diamonds can also have structural defects due to the presence of nitrogen, hydrogen or nickel atoms that may give the diamond its green appearance. However, natural irradiation is much more common.

Fancy Color Scale:  

As for all natural colored diamonds, they follow a similar color grading scale: faint green, very light green, light green, fancy light green, fancy green and fancy intense, vivid and deep. For green diamonds, the more intense, vivid or deep the natural color is, the more expensive the stone is.

Diamond cutting:

As we mentioned before, often times green diamond color is very shallow, so this presents diamond cutters with a problem. How to maximize the natural green color in an exceptionally rare diamond.

Famous Green Diamonds

In fact, Christie’s Auction sold the Aurora Green diamond in 2016 for $16.2 million. The sale made it the most expensive green diamond as well as the largest Fancy Vivid Natural Green Diamond.

Marquise Diamonds

One of the most unique and definitive engagement ring diamond cuts are marquise diamonds. Jewelers and fans also refer to marquise cuts as football cuts, cat-eye cuts and boat cuts because of the highly elongated elliptical shape. This 58 faceted diamond cut is actually a vintage style and looks great on long, slender fingers. Furthermore, this romantic cut breathes an aristocratic air and carries a royal pedigree.

According to the legend, marquise diamonds date back to the 18th century where “King Louis XV commissioned a jewelry to design a diamond cut that resembled the lips of Jean Antoinette Poisson, his mistress”. Furthermore, these diamonds also signify a rank just below duke, where individuals would actually wear these diamonds to signify said rank.

Additionally, gemologist originally design marquise cuts for diamonds, however jewelers now use these cuts with emeralds, rubies and sapphires.

Marquise Diamonds – TIPS

  • Marquise cuts are a fairly extreme cut when it comes to diamond cuts, so they are susceptible to chipping, so you may want to look for a mounting with protective prongs along the ends of the diamond.
  • A higher cut grade is important for the marquise diamond. Typically, elongated shapes tend to form a bow tie effect in the middle of the stone. Additionally, the symmetry of marquise cuts are very important.
  • One noticeable benefit is that marquise cuts tend to make the center stone look larger.

Do you like marquise diamonds? You know who else does too? Victoria Beckham, aka Posh Spice, Ashley Simpson and THE Catherine Zeta Jones.
