Top quality mined emeralds can easily top the value of natural diamonds.  And within the world of emeralds, Colombian emeralds are usually valued the highest due to their intense color with just a hint of blue.  Mined Colombian emeralds will typically sell for 10%-20% higher premium than emeralds from other countries.  

We are thus pleased to announce, that after 7 years of research by the Russian professor Dimitry Fursenko, lab-grown Colombian Emeralds are now a reality and we are pleased to offer them to our customers.

Our cultured (lab-grown) Colombian emeralds are unique in several respects:

• These are *real* emeralds, not imitation...they are simply grown in the lab instead of mined.
  
• Further blurring the line between mined and lab-grown, these emeralds are hydrothermally grown, using low-grade natural emeralds as their nutrient source.  Re-crystallization is a good term to describe what takes place, as small emeralds are crushed and then regrown around a new seed in the lab into large single crystals.
  
• While mined emeralds are known for their high inclusion rate (GIA grades them as Type III gems, meaning they are almost always included), we offer only gem quality (loupe-clean) cultured Colombian emeralds.  Further, unlike mined emeralds, our cultured Colombian emeralds are not 'oiled', a default process done to most mined emeralds to hide their inclusions whereby palm oil is applied under pressure to temporarily fill voids and defects.

The result is that our Cultured Colombian Emeralds let you enjoy the beauty and splendor of real emerald in sizes, clarity and color saturation that would otherwise be unaffordable (A large, deep green emerald with minor blue coloration that is relatively free of inclusions may cost up to tens of thousands of dollars per carat).  

We are introducing our Cultured Colombian Emeralds at $145/ct.
