INVESTMENT DIAMONDS

GemInfinity offers a tailor-made solution to enhance your wealth. With our expertise, GemInfinity carefully selects stones of exceptional quality for you, whether a single acquisition or long-term investment.

The certificates of authenticity that we issue guarantee the traceability and ethical sourcing of our stones. We provide you annually with all the necessary documents, from insurance attestations to grading certificates.

DIAMOND, COLOURED STONE AND PEARL GRADING

We analyse diamonds of all cuts, shapes and colours according to the 4 Cs: Carat, Clarity, Colour and Cut. For your diamonds, we issue SSG (Société Suisse de Gemmologie) attestations and certificates.

As GIA gemmologists, we identify gems of all families and varieties. We check whether stones are of natural or synthetic origin, or imitation stones and organic gemstones. We research potential treatments and can provide you with Gübelin, SSG or Gemlab attestations and certificates.

JEWELLERY AND WATCH APPRAISAL

Whether for insurance or inheritance purposes, we can assess, identify, date and value all your precious jewellery, whether gifts, bequests or purchases.

MELEE GRADING

We check the quality of and grade melees, diamonds or coloured stones for fine watches and pavé settings for jewellery. Our assessment is based on precise criteria, such as weight, cut, proportions, colour, clarity, fluorescence and uniformity.

BUYING AND SELLING ADVICE

Thanks to our extensive experience and in-depth market knowledge, we can offer personalised advice on purchasing, transforming or selling an item. We handle the sales of different items of value.

Our vintage jewels are showcased at My First Boutique, rue des Fontenailles 10, in Lausanne.

QUALITY CONTROL

We carry out quality control for gemstone and jewellery inventories. We provide a detailed report outlining the clarity, colour, cut, proportions and weight of stones, the manufacture and settings of the pieces as well as their consistency of quality.
