The 'Blue Book' of Wholesale Prices Since 1982

What is GCALMM.com?
Palmieri's Market Monitor, also known as GCALMM.com, is the 'blue book' of wholesale diamond and colored gemstone pricing available exclusively to members of the jewelry trade.
The Diamond Market Monitor® takes the guess work out of diamond pricing. Unlike most diamond price sheets that state inflated asking prices, the Market Monitor lists actual wholesale selling price ranges so you don't have to speculate at the discounts. With over 6,000 price categories, you can search for the exact shape, size and quality you need.

Advanced Research
For the advanced researcher, appraiser, collector or dealer, there is a treasure trove of prices and information dating back to 1982. The Auction Market Monitor® provides access hundreds of sales of Kashmir Sapphires, Burmese Rubies, Colombian Emeralds, and Fancy Colored Diamonds, as well as colorless diamonds up to and over 100 carats sold at major auction worldwide.
Quickly and easily research prices by filtering results by numerous parameters including: designer, item type, shape, carat, color, clarity, country of origin, auction location and year. Auction sales are the most transparent form of market information and accepted as comparables by the IRS

Published for over 35 years
In addition to pricing data and auction results, subscribers have access to a wealth of appraisal resources including: market guides, weight estimation calculators, photomicrograph galleries and up to date market analyses.
