CITRINE

This is generally known as Quartz or Topaz. This is really a yellow Quartz with peculiar internal structure, the colour being due probably to a trace of ferric oxide. Natural stones are not very common and most of the 'atrine' in the market are as a result of heating smoky Quartz. Although it is softer and much softer and much cheaper than Yellow Sapphire, when cut and polished it looks flawless and very long time. It is a very useful substitute for Yellow Sapphire and Topaz.
