I have searched online and I’ve only found one similar to this. This was bought in a thrift store so I have no way of authenticating it. It does have a sticker on the bottom that says “Eagle Metalart Co., Division of Eagle Regalia Co., Inc. New York, New York Founded in 1910.”The block is clear with a quarter inch of black at the bottom. The coral is suspended in the block. If you have any questions, please ask, and I will try to answer. 
Also, this was very hard to photograph well and I continually got fingerprints on it as well as dust which you can see in the photos. I believe it is clear of any scratches as I was able to polish any of the spots I was seeing.
