Mercury Diamond is a leading diamond pricing consultancy
The Mercury Polished Price Calculator estimates current market prices of a polished diamond based on all its characteristics, going beyond the traditional 4Cs. It takes into account comments and other irregularities (what we call the 5th C) found on a certificate, based on Mercury’s proprietary table of irregularities.
The tool derives a diamond’s price by retrieving most data automatically from a diamond’s certificate. If there is no certificate, the tool allows the user to manually enter any combination of the 5Cs.
This tool allows companies trading polished diamonds to investigate in real time a list of diamonds that can be purchased for a given budget.
The Mercury Rough Price Calculator provides a price estimation of a single stone depending on different yield assumptions.
The Mercury Rough Blocks Calculator allows a sorter or valuator to separate rough stones based on estimations of stone characteristics onto virtual pads to derive price estimations. The tool makes assortments below 10 carats. For diamonds above 10 carats, called specials, stone evaluations are made individually by using the Mercury Rough Price Calculator.
This tool shows trends in as well as gaps between (i) the price level of rough diamonds that is tied to what end users want to pay for the polished diamonds and (ii) the price level that is driven by dynamics of the rough market and the agendas of rough buyers, traders and manufacturers.
Mercury calls these price levels the Rough Baseline Price and the Rough Trading Price respectively.
The chart shows the gap between Rough Trading prices and the Rough Baseline prices (indexed) of different size categories at a particular point in time.
