Most people meet alexandrite twice. The first time is a photograph, and the photograph is usually a lie — not a deliberate one, but a stone that changes colour cannot be honestly served by a single image. The second time is in the hand, in daylight, and then again by candlelight in a dark room, when the green gives way to raspberry and red. That second meeting is the one that explains the price.
Natural alexandrite is priced on five things, and they compound rather than add.
The first and by far the largest is the colour change itself. A stone is judged on how completely it moves and how clean the two colours are at either end. A fine one goes from a true green — not a grey-green, not a yellow-green — to a clear raspberry or purplish red, with nothing muddy in between. A weak change, or a change between two indistinct colours, drops the price of an otherwise identical stone by a great deal. This single quality separates a remarkable alexandrite from a merely unusual one, and no amount of size makes up for its absence.
The second is size, and here alexandrite behaves unlike almost anything else. Fine material simply does not occur in quantity. Rough that yields a clean, strongly changing stone above two or three carats is genuinely uncommon, and above five carats it is the kind of thing a dealer remembers for years. Price per carat therefore does not rise in a line; it steps. A four-carat stone is not twice a two-carat stone. It is a different conversation.
The third is clarity and the fourth is cut, and they work together. Alexandrite is usually cut to serve the colour change rather than to chase maximum weight, which means a well-cut stone has often given up a visible amount of its rough to show both colours properly. Eye-clean material commands a premium, though a small inclusion that does nothing to the light is not a fault worth paying to avoid.
The fifth is origin. The first alexandrites came out of the Russian Urals in the 1830s, and those mines were substantially worked out within a few decades. What the world has had since comes chiefly from Brazil, Sri Lanka and East Africa. Fine Russian material still trades at a premium for reasons that are partly historical and partly real — the best of it set a standard the market still measures against — but origin is the last of the five, not the first. A superb Brazilian stone outprices a mediocre Russian one, and should.
Behind all five sits the plain fact of scarcity. Alexandrite is not rare in the way that a marketing department means rare. It is rare in the way that means a working jeweller can go a season without being offered one worth buying. Fine natural alexandrite in any real size is scarcer than a comparable diamond, and unlike diamond there is no steady supply behind it to smooth the peaks. When a good stone appears, it is bought, and it does not appear again on demand.
A word on what we do not say. We make no claim about what any stone will be worth later. Gem prices move for reasons no one controls, and a jeweller who promises appreciation is selling something other than jewellery. What we can tell you is what you own and prove it: every piece leaves us with its GIA certificate for the stone, enclosed in the package, and an independent appraisal sent to you digitally on the day it ships — both prepared by third parties, and neither charged for. Those documents exist so that you can insure the piece properly with an insurer of your choosing. They are documentation, not a valuation we are standing behind, and no insurer's acceptance is ours to guarantee.
What the price of a piece from us covers, beyond the stone, is the making. The setting is designed around that particular stone and its particular change, because a mounting that flatters a green stone in daylight can smother the red at night. Metal choice, the height and openness of the setting, how much light reaches the pavilion — these are decisions made for one stone, not selected from a catalogue. That is where the rest of the money goes, and it is the part a photograph never shows either.
If you are ever curious about how your own piece was arrived at — the stone that was chosen, why the setting sits the way it does, what was rejected along the way — write to me and ask. It is my favourite question and it is never an imposition.
