How the numbers work.
Market reference
The model's reference value for the stone. For rough stones it is based on the expected finished weight after yield.
Maximum buy
The net value, after any cutting and lab costs you enter, divided by your target return multiple.
Best bargain and opening offer
Price levels set below your maximum buy by the model's negotiation ladder, to guide your offers.
The decision
BUY if the dealer's ask is at or below the best-bargain level. NEGOTIATE if it is above that but within your maximum. WALK AWAY if it is above your maximum.
Treatment
The treatment level applies only to rough corundum.
