Incredible Mark Eckstrand Cased Glass "Aquarium Paperweight" with what I like to call a colorful, sharp-toothed killer shark floating above the reef.  The tall green seaweed is Aventurine and there are so many interesting, colorful items growing/seen on this reef.  Pink, yellow, green, aqua blue, brown and black are the primary colors I see.

WEIGHS 4 LBS 14 OUNCES!   Is approximately 4.5" W X 4.4" H.  Signed "Eckstand" and dated "90" on base...Pontil sticks out of base a bit on one side so sits slightly unevenly.  See photos.
