When buying gemstones it is imperative that you ensure the gemstones are authentic. There are many ways the appearance of a gemstone can be enhanced, so enlisting a qualified valuer to assess and authenticate the quality of your gemstone/s is absolutely essential.
Gemstone fraud has become increasingly prevalent and sophisticated so it is important you carry out due diligence to ensure the authenticity of any stones before purchase. This is especially important if you are purchasing stones from a new supplier. A pre-purchase assessment is a prudent investment against unscrupulous operators.
