Is your Gold Ring Gemstone Real or Fake ?

Ever wondered if the Gold ring or Silver pendant that a kind granny left to you has a real or fake diamond mounted on or in it? Well if you are you deliberating whether or not to sell scrap gold including your stone(s) or if you are just interested in identifying the stone make up then you can take the item to a qualified jeweller for an assessment but this may cost you a fee! so I thought I would help the process by sharing a few facts (not exhaustive) that may help you make your own mind up or at least give you an indication.

Brief History of Simulated Gem Stones

It is noticeable that from a very early period the imitation of gems was attempted. The Romans in particular were very skilful in the production of coloured-glass pastes, which were extremely good at copying Emeralds and the beautiful deep blue” lapis” lazuli. With an increasing demand for jewellery, throughout the world the amount of imitations steadily increased. In 1758 the Viennese goldsmith Joseph Strasser succeeded in formulating a colourless glass based paste that could be cut and could actually superficially copy the sparkle of a genuine diamond; the products of this paste are called strass stones.

How do Paste and Glass imitations differ from a real stones?

As a rule of thumb Pastes are softer than ordinary or crown glass but have a higher level of refraction and dispersion that give them great brilliancy and fire in the short term anyway. The cheaper paste imitations are pressed or moulded, but, on the better-quality stones, you are able to cut the surfaces and polish them.

Moulded-glass gem stone imitations can be identified with a cheap eye glass available on the Internet, because the edges between the facet surfaces can be studied and are rounded whereas cut glass has sharp edges. Cut paste stones may be distinguished from real gem stones in several ways:

Paste stones have air bubbles, natural stones do not

Paste is also a poor conductor of heat, and so paste stones feel warm to the touch – This is probably the main quick source of testing whether a stone is fake or real but obviously has its limitations but I see people at antique fairs referring to “touch” method all the time for an indication of authenticity.

Other differentiation methods involve hardness as paste is softer than real stones and will not scratch     ordinary glass and will break up if hammered!

A Real diamond for example is one of the hardest materials in the world!

Paste also tends to scratch and mark easily as a Diamond for instance does not - Please example below;
