Rough clear Topaz
Lovely gemmy pieces of clear Topaz, in the rough. They are sold in 10 gram bags.
This material is usually used by lapidaries as cutting practice before moving on to higher quality Topaz material with colour.
If you are looking to cut these stones, I would recommend the Grade A bags. They have been handpicked as pieces that look clearer, although they may still have some iron staining etc. Some of these stones would make excellent faceting rough for practising working with Topaz and may cut some sellable stones too.
However, considering the price, I think it ought to appeal to collectors too. You get quite a lot of material for the money – these ten gram packets contain around 4-10 pieces. The pieces are typically around 7-13MM each.
