Returns a page of Ada's live loose lab grown diamond inventory, filtered by shape, carat, price, color, clarity, and cut. Stones sell continuously, so treat results as a snapshot and call `getDiamond` to re-check a specific stone before quoting it. Prices are US dollars for the loose stone only; add a setting from `listEngagementRings` to quote a finished ring.
