Which term corresponds to a grooved tray used for matching stones?

Explanation:
When you need to compare stones side by side, you use a tray with grooves to hold each stone in a fixed position. This setup lets you quickly assess face-up appearance, color, and overall similarity without stones rolling or mixing. The term for this specific tool is a matching tray. It’s distinct from an aperture, which is just an opening; a sorting pad, used for rough sorting, and a sieve set, which sorts by size using mesh screens.
