More Fake Rough Diamond Crystals Reported

The Gemlab Research Newsletter dated March 23 reports that more fake diamond crystals, “ingeniously designed rough diamond imitations,” have appeared in the trade.
Noting the beautiful craftsmanship of the crystals to appear like diamond, Thomas Hainschwang of GEMLAB, Laboratory for Gemstone Analysis and Reports in Balzers, Liechtenstein, who sent the report, observed that the crystals were noticeably void of trigons, the triangular etch marks commonly found on octahedral diamond crystals.
That led to some basic testing with Polaroid plates which determined that the crystals could not be diamond. Hainschwang says that phenakite as the likely substitute.
JCK reported on such imitation diamond rough in March of 2007.

Is this the actual picture of the fake rough? or just a stock photo.
Would be interesting to know this.

Hi there,
I too have just been scammed. I live in Los Angeles, Ca and the purchasing of this fake happened in Washington DC. This piece passed all tests. It took 3 cutters to figure out what it is? I still have the stone in my possession. 20.73 carat.

If anyone would like to sell an octahedron fake piece of rough, I am an appraiser, and would love to have one for my collection. I am not sure what it would be worth but I would be willing to consider an appropriate amount.
