The Synthetic stones are commonly of the corundum (Saphire)type or the Spinel type. These are grown inside a flame, from their relevant chemicals. The resulting stone is termed a "BOULE". In recent years more stones are simulated by laboratory grown "NATURAL" crystals. In other words they are grown from the same chemicals as nature uses, and are therefore almost impossible to tell from the natural stones. Cubic zirconia comes in so many colours that many stones are now also imitated by this synthetic. You can usually tell because they are just too brilliant. Wal.

FORGING is a method of deforming metal with a hammer on an anvil. In the case of Sterling Silver and the Karat Golds, this must be done COLD! If a hot forging is attempted the precious metals will just crumble. In their PURE form Silver and Gold will allow HOT forging, but there is no benefit to be gained. Wal.
