Perhaps there is no cleaner, purer, more beautiful coating on druzy than Platinum . The crisp silver sparkle that emanates from the gorgeous pieces will never tarnish because the coating is genuine platinum. Of course these are from the collection of Greg Genovese, who combines elegant cuts with a selection of natural and dyed agate surrounds. As with all precious metal coated druzy, the coating on these pieces is permanent, as long as they are never machine-buffed. Instead, gently swirl through warm soapy water, rinse with distilled water and blow dry. Best also to store in closed bags or sealed containers.
