Why we send you one stone, not a hundred.
Open any diamond marketplace, type in 1.50 ct, F, VS1, round, excellent cut, and you get a list. Four hundred stones, give or take, sorted by price. The cheapest ones sit at the top. Most jewellers we talk to scroll through, open a few videos, compare two or three prices, and pick the one that looks fine on a phone screen. Then they hope.
The list is not the problem. The list is the whole offer, and it stops exactly where the work begins.
What the list cannot tell you
Two stones with identical reports can look like different stones. One has a faint brown tint the report calls F. One has a feather under the table that is graded VS1 but catches the light at the wrong angle. One is cut to maximise weight and faces up small for its carat. One has medium blue fluorescence that makes it look milky in daylight. None of this is on the report, and most of it is hard to see in a video shot by a seller who wants to sell it.
At the bourse, we put the three candidates on a white tray next to each other, under daylight and under the loupe, and the differences are obvious in about a minute. That minute is the service.
What we do with your brief
A brief arrives: round, about 1.50 ct, F to G, VS, natural, GIA, for a platinum four-claw solitaire, client budget known, needed in three weeks. We read it the way you would read a client across the counter. The client wants a white, lively stone that looks like 1.50 ct. So we skip the stones cut deep for weight, skip anything with strong fluorescence, and we do not spend your budget on a clarity grade nobody will ever see once it is set.
Then we walk. The bourse holds roughly 2,500 offices, and the parcels for a brief like this sit in perhaps a dozen of them. We ask for stones, see them, and come back with two or three that we would buy ourselves. Each one gets a video shot under the same light, the report, the measurements, and one landed price in your currency.
Why two or three, and not one
Because you know your client and we do not. One stone is slightly whiter, one is slightly larger, one is slightly less expensive. You choose. We have already removed the ones that would have disappointed.
What this costs you
Usually less than the list. A marketplace stone carries the seller's margin, the platform's margin and a shipping charge you discover at checkout. Our fee is built into the landed price and we tell you what it is. More to the point, a stone that comes back from the client because it looked grey against the yellow gold costs more than any fee.
The list ends where the work begins. We start there.
If you would like to try it, send a brief. Describe the stone the way your client described it to you. We will do the translating.
