Sphalerite Gemstones from Spain and Bulgaria

Sphalerite is one of the more intriguing gems out there, as it is one the few transparent sulfides in the world that is actually suitable for faceting.  Typically Sphalerite is found in opaque black crystals, and transparent material is not common.  One of my favorite aspects of gem grade Sphalerite is the amazingly high dispersion of 0.156 which is over three times that of Diamond!  Additionally, Sphalerite is fairly dense when compared to most other gems such as Quartz, Beryl or Topaz, so even smaller stones carry plenty of weight, which translates into value for one's money.  When the stones are polished correctly, the luster is amazingly bright and often described as being adamantine.  Sphalerite is one of the very few minerals to have a total of six directions of cleavage, making faceting treacherous, and only skilled gem cutters have the ability to cut the material properly.  The color of Sphalerite is certainly enhanced by its high dispersion, and the fire that is seen in faceted stones is robust enough that is observed easily even in the stones with deeper colors.  The most sought after hues for gem Sphalerite are red and green, but the range of colors in between is vast, ranging from completely colorless to deep and intense shades of red, blue-green, gold, and orange.   The following gemstones represent some of our finest available faceted Sphalerites from Spain and Bulgaria, and all of them feature top luster / polish and beautiful concave faceting, which brings out more of the life of the gems as the light has more directions to move inside the stone.

      Cut: Concave Round
Color: Orange

Comments:

This gorgeous Sphalerite has a combination of fiery orange and yellow color with streaks of deep red.  Clarity of this caliber is almost unheard of for Sphalerite and with the dwindling supply of Spanish material; stones like this one are extremely rare.  The stone has a "Concave Round" cut that displays outstanding brilliance.  Add the fact that this stone is nearly 7.5 cts and you have all the qualifications for a "killer" gemstone.  The photos simply do not this gem justice, and when you view it in person, it becomes one of those gems that you can still see after you close your eyes!

Comments:

Here is one gem that displays an illusion, almost that of a fireworks show.  It is spectacular in person.  This stunning Sphalerite is a “blood orange” red color, that simply cannot be replicated in the photos.  Much better in person.  This gem has a premium color with clarity that is well ABOVE average for this material, and the fact that it weighs over 10 carats makes it an incredible rare stone for any collector.  Don't miss out on this one, especially if you've been looking for a good faceted Sphalerite for you collection.

Comments:

This stunning gem is an eye catching green color - some of us have refereed to the color in this stone as "kryptonite green".  This color is highly sought after in good Bulgarian material, as green is not a common hue to find in gem quality Sphalerite around the world.  A truly exceptional gemstone and the fact that it is 7.51cts is just icing on the cake.
