Today, many websites promise to estimate the value of your jewellery in seconds using artificial intelligence. Yet a gemstone or a piece of jewellery cannot be properly assessed from a photograph alone. Its colour, inclusions, cut, hallmarks and signs of its age must be examined under a magnifying loupe, in the hands of a professional.
Parting with a piece of jewellery is never a trivial decision. It deserves to be examined by a real person, not simply scanned like a supermarket product.
Entrusting your jewellery to Julie Mialet means choosing recognised gemmological expertise, with complete discretion. At Pierres de Julie, your gemstone and jewellery are examined in person: no forms to fill in and no automated valuations, just the trained eye of an expert who personally stands behind her assessment. With a free initial appraisal, you can quickly obtain an accurate idea of the true value of your precious gemstone or antique jewellery, accompanied by clear and honest explanations.
A qualified expert who graduated from the Institut National de Gemmologie in 2004, Julie Mialet rigorously assesses gemstone quality, drawing in particular on certificates issued by the Laboratoire Français de Gemmologie or GEMPARIS. She can also help you transform your family jewellery into bespoke contemporary creations. Whether you want to choose a gemstone, verify its authenticity or design a unique setting, Julie will guide you with passion and expertise.
Whether you wish to sell, transform or exchange your jewellery, Julie takes the time to listen to you, understand your plans and advise you on the options available. She then guides you through every stage of the process.
An algorithm can display a figure, but only a person can offer you genuine advice.
Verbal appraisals of precious and semi-precious gemstones or jewellery are complimentary. We will not charge you any fees or ask for any payment.
Written appraisals, which carry our professional responsibility, start at €280.00 including VAT for 1 to 4 pieces of jewellery. Fees then increase according to the number of jewellery items or gemstones and the complexity of the research involved.
Julie Mialet examines your piece under a magnifying loupe, explains what she observes and gives you a clear valuation. If you accept the offer, the sale is completed immediately and payment is made in full on the spot: no waiting, no posting items, no intermediaries.
Selling is not your only option. Julie can also advise you if you would like to transform or exchange your jewellery, supporting you throughout the process whatever you decide.
Pierres de Julie is about much more than diamonds. You will discover a wide range of coloured gemstones, including sapphires, rubies, emeralds, aquamarines, tanzanites, tourmalines and morganites. Each gemstone is selected for its rarity, beauty and unique brilliance.
