Interesting article about fake rough Diamonds. Looks like someone has spent time engraving triangles on Topaz to make it look like a Diamond.

Being SR vs DR should be easy to detect, but if people are just going by visual appearance there is chance they could get confused.

i have seen phenakite as replica of rough diamond not colorless Topaz crystals as it says in this article.

actually i think making blue topaz by irradiating colorless topaz worth much more

I remember seeing a piece somewhere about synthetic white spinel crystals being sold as rough diamonds. They even displayed trigons but were inverted from diamond trigons -- the quick way to ID them. They have the "benefit" of being SR.
