Jewelry Report
IDGL Jewelry Reports are issued for pieces featuring natural and lab grown diamonds and gemstones. Each report provides all gemstone and mounting specifics, and clear standardized photos showing craftsmanship details that may not otherwise be visible.
Commitment to Confidence
IDGL was the first laboratory to develop jewelry reports and continues to lead the field today.
More complex than the analysis of loose gemstones, IDGL’s expertise in the analysis and documentation of finished jewelry items is unrivaled anywhere. Without disassembling heirlooms or complex pieces, IDGL performs thorough, objective and expert analysis of finished jewelry items.
IDGL screens every gemstone using state of the art technologies to determine naturally mined, laboratory grown or simulant origin. Experienced graduate gemologists conduct further assessment in controlled conditions, detailing relevant gemological characteristics according to the strictest international system. The presence of any treatments will be noted in the comments section.
