Bluebird Diamond

Jewelry Discussion

Hey Gang

I just received a diamond ring from my husband that belonged to a
deceased sister. The centre stone used to be in his mother’s
engagement ring which was purchased in the 1920’s. It was appraised
many years ago as a .39 carat SI 1 graded at I to K colour. His other
sister remembers it as a Bluebird diamond and I am trying to find out
what this means. Is this a certain cut or just a trade name for
manufacturers brand? Thank you.

Just a brand name. No gemological meaning. As with most such, the
brand was supposed to imply quality, but in those days before GIA
grading, when few jewelers or even manufacturers had any real
gemological training or knowledge and virtually all qualities of
diamond were often sold as blue/white and perfect, well, quality
simply meant little more than that you could probably trust the
company to be really nice people while they were selling you the
diamond.

Karen,

This may be a confusion with the old term “blue-white”, often used
many years ago to indicate a white body color with medium to strong
blue fluorescence.

Karen,

Bluebird diamond was a trade name that a company used to call their
bridal line. It was a wholesaler, from Chicago I believe, called
Stein & Ellbogen(too many years have passed I may have the last name
wrong). Their stamp inside rings was S&E. That was back in the day
when many people felt that you had to have a “name” for your bridal
line. The company went the way of many wholesalers around twenty
years ago.
