Claim:
1. A stackable container sized and configured for containing a plurality of individual gemstones comprising: an optically clear lid of a planar optical quality having an upper surface with a first optical property, the lid having an underside coating of a clear adhesive gel composition having a second optical property, the underside coating releasably holding the plurality of individual gemstones in fixed position on an underside of the lid during transportation of the container; and a base sized to register with the lid, and configured to clamp releasably to the lid with a frictional clamping force, without hinges and without a snap fit closure, the base further sized to provide a gemstone containment volume for the plurality of individual gemstones between the underside of the lid and the base, the containment volume having a depth such that when the plurality of individual gemstones is contained within the containment volume, the plurality of individual gemstones does not touch an upper surface of the base, and the plurality of individual gemstones is viewable in 360 degrees; wherein the first and second optical properties are selected to allow the plurality of individual gemstones contained therein to each be evaluated by a naked eye, or with a loupe, through the lid of the container without need to remove each individual gemstones from the container for evaluation; wherein the frictional clamping force maintains the stackable container closed, and when the stackable container is opened in normal use, the frictional clamping force is overcome without dislodging of a contained gemstone of the plurality of individual gemstones from the underside coating; and wherein an upper region of the lid is adapted to friction-mount releasably to an underside of a base of a second stackable container; and a lower region of the base is adapted to friction mount releasably to an upper region of a lid of a third stackable container such that a plurality of stackable containers are stackable in an array.
