What is the fastest way to spot an agate in a gravel bed?+
Look for waxy luster and translucence rather than color. Wet the stone or look right after rain: agate glows softly at thin edges when backlit, while jasper and chert stay opaque. Banding clinches it but is often hidden until the stone is cracked or tumbled.
