Setting a retail margin on jewelry bought at a show
Keystone and triple key explained, where each belongs, and the categories - certificated stones, gold by weight, branded watches - where neither applies.
The margin on a piece is decided twice: once at the stand, when you agree a cost, and once at the counter, months later, when a customer asks the price. Buyers who assume the second decision is the real one usually find the first one already made it. A piece bought badly cannot be priced well.
Two pieces of trade shorthand do most of the work here. Keystone means doubling the cost: a piece that lands at four hundred is tagged at eight hundred. Triple key means tripling it. Both are routinely mis-stated, because markup and margin are measured from opposite ends. Keystone is a hundred percent markup on cost but a fifty percent margin on the retail price. Triple key is two hundred percent markup and a margin of roughly sixty-seven percent. Promise fifty percent markup and deliver keystone and you have promised the wrong thing, by enough to change what an assortment earns in a year.
What keystone is actually paying for
Keystone sounds generous until you list what sits underneath it. Rent on a street-facing space, staff who spend an hour on a sale that may not close, insurance on stock that sits rather than moves, the cost of capital tied up in goods, sizing and setting, polishing and rhodium, repairs done at no charge to keep a customer, markdowns on what never sold. Fine jewelry turns slowly compared with almost any other retail category, and a piece may sit a year before it finds its buyer. Keystone is not profit; it is the gross number a shop is run out of.
Where triple key still holds
Triple key survives where cost is small relative to what the piece is worth to the customer and the work of selling it is large. Silver and fashion jewelry, bridge lines, design-led work from an independent maker: anything with a low ticket and a high handling cost. An item costing thirty at wholesale cannot be sold at keystone and still pay for the fifteen minutes at the counter, the box, the card and the rent it occupied for eight months. One-off designer pieces follow the same logic, since there is nothing for a customer to price them against.
The categories where neither number applies
Certificated loose diamonds are the clearest case. A stone with a grading report is close to a commodity: the report describes it in exactly the terms a customer types into a search box, and they do that before they walk in. Margins on certificated goods are commonly a fraction of keystone, often in the teens or twenties rather than the fifties. The same pressure reaches bridal centre stones, which is why many retailers hold a thin margin on the stone and a healthier one on the mounting and the setting labour.
Gold sold by weight behaves the same way for a different reason. Plain chain, bangles and plain bands are priced off the metal: a cost per gram tied to the day's spot, plus a making charge. The customer can weigh the piece and do the arithmetic, and in the markets where this trade is largest, they will. Margin there is a percentage over metal and labour rather than a multiple of cost. Branded watches are the far end of the same problem: the supplier sets the retail price and the margin arrives with the agency.
- Landed cost rather than the invoice: freight, insurance, duty, bank charges and the exchange rate you will actually be given.
- The finishing you pay for after delivery: sizing, setting, polishing, rhodium, a photograph for the website.
- Whether a customer can price the piece from a search box, and what they will find.
- How fast the category turned last year, because slow stock needs more margin, not less.
- The repair and return history of the line, which is margin given back.
- What this category must reach for the assortment to hold its blended target.
Blend it, and build it on landed cost
The useful target is not a margin per piece but a blended margin across the assortment. A case of certificated stones at twenty percent and a silver line at triple key can average to something healthy, while a shop that insists on keystone everywhere loses the diamond business to whoever did the arithmetic properly. Decide the blended number first and let each category carry what it can bear. All of it is computed on landed cost. A margin measured against the figure on a stand's invoice is a margin you do not have.
Keystone is a default, not a policy. The policy is knowing which of your cases could never support it, and what the rest of the floor has to earn to cover the difference.
Each floor in a twelve-city year pushes you toward a different kind of margin. Valumira runs Friday to Sunday in each city, Friday reserved for the trade, from Las Vegas in November 2026 through to Sydney in October 2027. The diamond floor in Antwerp in June is a thin-margin, price-visible buy. The Italian gold and chain in Vicenza in May prices off weight and making charge. The antique and designer halls in London in July hold pieces no customer can compare with anything. Carry one page with your blended target and the margin each category has to hit, and price the goods in the aisle rather than after they arrive.
