BlueZircon gems are redish-brown stones when mined and later  heated at low temperature before to turn blue.  Here  is a rough intended for lapidary.  Rough: 39,10 cts of the TOPEST Blue. The stone has only a few feathers on its edge that would be removed by any cutting style. You can expect a range size about 11 to 15 carats after cutting.   Here is to say that "Zircon" stones are fully natural and have nothing to deal with the artificial stone (used as a synthetic diamond) named "Zirconia".   Zircon stones are mostly clean stone, hardly included.
