Jewel Co. Bronze and Marble Aquarium

This was made in Chicago in the 1920's.
This company was known for it's elaborate work in cast iron.

Also found this: "Bonhams & Butterfields' spring 2008 auction of 20th Century Decorative Arts, to be held in Los Angeles on Wednesday, April 7, 2007, features a diverse group of master works spanning a century of design. Strong examples of Arts & Crafts, Art Nouveau, Art Deco, Mid-Century Modern and works by Contemporary Studio artists come to the block.

Offerings include an unusual Art Deco wrought-iron, marble and glass Seahorse aquarium, 1920s, from the Jewel Aquarium Company (est. $5,000/7,000)."

No idea if yours is the exact same but you could contact them and find out.
Good luck, looks like you have a nice one there.

 jewel aquarium mfg went out-of-business in 1982.  the company was located in the 5000 block of west armitage ave (in chicago of course)

all their product of all types was of the highest quality manufacture and are definitely worth the effort to restore

however all the tanks they ever made had bottoms made of slate, not glass. since all jewel tanks now are at least 40 yrs old that can be a problem if you want the tank still to be leakproof, as the original factory sealing is likely dried out and as such not watertite.  the situation's made worse if you're faced with replacing a cracked side glass pane.  modern sealants simply are not successful against the surface porosity of slate, and the original factory caulk was a custom formula long since assigned to history.  slate was used then because you could drop accidently a large rock inside the tank and crack a glass bottom but never crack the slate one.

also i might point out such old aquarium tanks are freshwater only, as metal frame's unsuitable for saltwater use

Hi CaveGal,

I have the exact same Jewel fish tank that you once had. Can you share with me how you went about selling the tank? Thank you.

Hey Cavegal,  did you ever sell it ?

I have been looking at antique fish tanks

Thx, Mike
