Estate jewellery sells on two things at once: the piece itself, and the fact that there is only one of it in that size. A ring is a period, a metal, a hallmark, a stone with a cut that dates it, and a finger size that either fits or has to be altered. That last detail decides more sales than anything else on the page, because a buyer who loves a ring in the wrong size needs to know before ordering whether it can be sized, by how much, at what cost, and whether sizing voids the return. Demand is also seasonal in a way most luxury categories are not. Proposals cluster in the winter months and around holidays, so a year's engagement revenue is decided in a handful of weeks.
We grow estate jewellery sellers who already sell online by working visitors, conversion rate, average order value and repeat purchases. It starts with a free written growth plan built on your own stock, sizing and enquiry data, then a base fee plus growth share scoped in that plan.
They want to know what it is and when it was made. Period, metal and purity, the hallmark or assay marks and what they date the piece to, the maker if there is a mark, and the country of origin. For anything described as a period piece, the marks are the evidence and buyers expect to see a close photograph of them.
Then the stones. Type, weight or approximate weight, cut, colour and clarity where they have been assessed, and crucially whether there is an independent report. Older stones are cut differently from modern ones. An old mine or old European cut throws light in a way that a modern brilliant does not, and the buyer choosing an antique ring is often choosing exactly that, so the cut needs to be named rather than glossed as diamond. Treatments have to be stated: heat on sapphires, oiling on emeralds, any filling or coating. Silence here is what disputes are made of.
Then fit and wearability. Finger size as it is now, whether it can be sized up or down and by how much, whether an eternity band or a carved shank makes sizing impossible, and what alteration costs. Bracelet and necklace lengths, and the weight of the piece, because heavy earrings are a real objection.
Last, the practical. Insurance valuation, insured delivery with signature, returns and how sizing affects them, and payment options for a piece that costs as much as a car.
