The video shows a close-up view of several clear glass trays containing multiple opal stones on top of white electronic scales, inside a glass display case. The opals show various colors, including blues, greens, reds, and whites, with some exhibiting a multi-colored play-of-color effect. Above and behind the trays on scales, there is a larger tray with more opals, organized in rows by color and opacity. Some of the other trays below in the display case show opals with solid greens or solid blues. The video angle shifts slightly, showing more trays of opals in the background.
