Alba is strongly committed to protect whoever purchases Alba white truffles. The precious "grey diamond" cannot be brought away from the market area without having been examined by strict "truffle judges". A specific body has been established, aimed at certifying truffles purchased at Alba White Truffle World Market at cortile della Maddalena, and thus being responsible for guaranteeing strict quality requirements. Five unique rules identify any Tuber Magnatum Pico purchased in Alba:

1. The appointed Commissione di controllo (Commission responsible for checking the truffles) works among market stands. One commission representative at least is actively present in the selling area to support consumers when buying truffles. The so-called "truffle judges" check truffles before they are sold in strict compliance with the rules stated by Carta della Qualità del Tuber Magnatum Pico, the quality charter drafted by Centro Nazionale Studi Tartufo (Alba National Centre for Truffle Studies), the most qualified centre for the analysis and the valorisation of truffle.

2. In order to guarantee the highest reliability, the purchased truffle is wrapped and put in numbered bags that uniquely identify truffle vendors.

3. The uniqueness of Alba White Truffle World Market is furtherly protected by a specific Mayor’s order that forbids the truffles to be sold outside the dedicated show area and shops.

4. In order to guarantee truffles are properly preserved, Mercato Mondiale del Tartufo (Alba White Truffle World Market) are equipped with dedicated cold areas to store the precious Tuber – and its unmistakable scent – in the best conditions, for its purchaser’s pleasure.

5. Last but not least, this year trifolao are equipped with electronic balances to precisely weigh the precious white diamond.
