Are you looking to purchase or invest into a diamond? We often come across customers, who would like to invest into diamonds, but are not sure how to go about it.

When it comes to purchasing diamonds it is essential to realise that the size of the diamond is not the only factor that determines its price. In fact, there are 5 major factors to take into account: WEIGHT, COLOUR, CLARITY, PROPORTION and CUT. Furthermore there are other factors that can affect its price, such as fluorescence.

Based on these attributes you can easily verify the price in the Rappaport, the Gemguide or in our store.

When purchasing a diamond always request a written guarantee of its attributes such as the main ones above: weight, clarity, colour, cut, proportion and also request a guarantee that the diamond is in fact natural and if it’s not then what sort of treatment has been conducted (heating, diffusion, laser drilling etc.).

Another thing to keep an eye out for is the certificate itself. Some companies emit unreliable certificates. Always request a certificate from a prestigious institution (GIA, HRD, DPL) or a well-established company with long term experience.
When choosing a reliable diamond trader always look at the amount of relevant information they are able to provide you with.

We are more than happy to guide you through the entire process of diamond or gemstone purchasing. We strongly recommend arranging an appointment with our certified gemmologist Martin Cinolter.
