The selection process of precious stone quality requires particular ability in selecting and assessing the quality of traded precious stone. The diversity types of precious stone and consumers in choosing it become an obstacle since the limited knowledge and ability to analyze needs of individuals. This research applied quantitative method by employing Fuzzi AHP model. The data was collected by consulting the director of Kantor Promosi Batu Mulia Indonesia GEMAFIA GROUP located in Bandung that gives some criteria in the selection of precious stone trade quality. Further, these criteria are formulated based on AHP pair comparison to find out the informational quality and upper expected values using TFT (triangular Fuzzy Number). The result that is based on Fuzzy AHP method show that density, color, hardness, cutting and clarity criteria are the main criteria in selecting precious stone trade quality. This method in the assessment of consistency level is done in the hierarchy structure level and is able to accommodate the assessment inconsistency.
