The most common error in this tier is pricing from cost plus a multiple, which produces a number the market either accepts or ignores with no way to tell which in advance. The more useful approach is to establish the price the position requires and then ask what specification that price genuinely supports — a conversation that occasionally ends with us saying the position needs a different material class.
Amber makes this concrete because the cost drivers are legible. Diameter, material class and selection yield account for most of the difference between a good piece and an exceptional one, and each can be moved deliberately. A house that understands those three levers can hold a price point across seasons as material markets move, which is worth more than any single favourable quotation.
We publish an indicative per-gram structure by diameter precisely so this conversation can start before anyone has committed. It is labelled indicative because batch and specification move it, and we would rather be checked than trusted.
