Lot of Tanzanian "Moldavite" Facet Rough from Tanzania. This material was sent to us as a sample of Tanzanian "Moldavite" and to our surprise we were shocked at how different the color was from the normal Tanzanian "Moldavite" we were accustomed to seeing in the market. We have always had our reservations on the origin of Tanzanian "Moldavite" and its natural nature. GIA has already documented the Emerald Green "Moldavite" as being man made and this enhances that argument. This material shows very slight color swirls which seem to indicate that color was implanted into the glass to produce the Minty look. That is what we have concluded from our experience and though we may not be right in that assumption it is VERY reasonable to make. Most of these stones are practically eye-clean and with a rare bubble internally you should get very clean finished cut stones out of these.

We are selling this material as Glass and we are NOT certifying it as being natural. Many sellers sell this material as natural and that is a great injustice to those that don't know all that is to be known about this material. This was sent to us as a sample and we have been informed that we can get this material in whatever color we would like (Makes you think...) and we are looking into the possibility of getting additional material for the future in different colors.

  1. We have often heard the argument that this material comes from a far off location in Tanzania where it is unrealistic to conclude that this material is man made. Natives are said to be grinding the rough into these nodules to clear out inclusions. We have even heard of samples out in the market that look like they are natural because they weren't grinded in such fashion. I think it is fairly reasonable to assume that something is being hidden when locals need to grind this rough in order to market it. In addition, our discovery of Blue "Natural" Moldavite in Pakistan that closely resembled the Tanzanian material further cast doubt on the origin of Tanzanian "Moldavite" as being natural. It seems as though molten glass is poured onto natural rock and dirt to give the appearance of it being natural because of the inclusions.
