Note:   Strictly speaking this is not a rose bowl since it has a slight lip going vertical.  This piece of glass is not missing anything like a spout or lid.  Other pieces in the Northwood Jewel pattern, have been seen with the top of the bowl bing flat or no vertical lip.  For the sack of identification we have included on this website.  

Color of Bowl:  Base glass is flint (clear) with a partial Ruby casing also called rubina.

The amount of Ruby casing glass varies from very little on some pieces of Northwood Jewel to almost complete coverage on others.  Expect varying about of rubina application.
