• A. A grooved white non-reflective tray used for matching sets of stones.
• B. A reflective metal tray for weighing stones.
• C. A velvet-lined tray for display.
• D. A plastic tray with colored compartments.

Answer: (A)

A Matching Tray is a grooved white non-reflective tray designed for arranging and comparing sets of stones side by side. The grooves keep each stone securely in place and in alignment, making it easy to assess color, tone, and overall appearance across a group. The white, non-reflective surface minimizes glare and color reflections that could bias judgment, providing a consistent background for evaluating how stones match each other. This makes it ideal when building a matched set or checking consistency across stones. Other trays described are intended for weighing, display, or have added colors that can introduce glare or color bias, which isn’t suitable for careful matching.
