Marjorie Vallotton, CEO

A gemmologist trained by the prestigious Gemological Institute of America (GIA) in New York, Marjorie Vallotton completed her studies with a degree in the history of jewellery from Sotheby’s Institute in London before joining the jewellery department at Sotheby's Geneva as an expert in gemmology and the history of jewellery.

In 2002, she opened Lumière du Nord, today known as Vallotton Treasures Sàrl, valuation and appraisal office for jewellery, diamonds, pearls and gemstones, with premises on Lausanne’s exclusive Rue de Bourg. Through GemInfinity, Marjorie Vallotton complements her appraisal and sales advice services with a department specialising in the acquisition of investment diamonds.

A specialist appraiser with extensive experience in gemmology, Marjorie Vallotton issues all the certificates and attestations required for insurance, resale, divorce, inheritance and division purposes. These documents are recognised by notaries, lawyers, banks, courts and debt enforcement offices.

The team at Vallotton Treasures Sàrl will also handle the sale of your jewellery and gemstones. With hundreds of appraisals under its belt, both for private and business customers, it guarantees total discretion. Your items of value are in safe hands at the firm’s secure premises.

Marjorie Vallotton shares her passion for diamonds and gemstones at gemmology conferences.

Enfin un site pour faire tranquillement son choix de bijoux à domicile. Grâce aux services proposés par GemInfinity j’ai fait de très belles acquisitions telles que boucles d’oreilles et bagues avec magnifiques diamants, montre ainsi qu’un magnifique collier de perles, ceux-ci de très bonne qualité et à des prix raisonnables. D’autre part, dans la catégorie ‘créateur’ je suis fan absolue de “Ma Snob de Soeur” et n’ai que des compliments lorsque je porte une de ses créations. Je souhaite plein succès à cette nouvelle initiative
