Abstract: An exemplary embodiment provides a stackable container for gemstones that has an optically clear lid having an optically planar upper surface with a first optical property, such as a refractive index. The lid has an underside coating of a clear gel adhesive having a second optical property matched with the first optical property to minimize optical distortion. The gel releasably adheres gemstones to the lid. The base and lid of the stackable container clamp releasably together without hinges and without a snap fit closure. The container has a gemstone containment volume wherein gemstones appear to “float” and can be examined. For stackability, an upper region of the lid mounts releasably to an underside of a base of a like second stackable container; and the base mounts releasably to an upper region of a lid of a like third stackable container such that a plurality of stackable containers are stackable in an array.
