This is a wonderful iridized art glass vase made by Correia Art Glass Studio of Santa Monica, California circa 1974.  It has the sought-after "Pulled Feather" pattern with green and blue on white shimmering iridization.

It is blown glass (Correia Glass Studio uses no moulds) and has the pontil mark on the bottom from manufacturing.

It is signed (etched) on the bottom "Roland R Correia V-525*74." "Roland R Correia" was signature used by the business partnership of Steven V. Correia and Roger Roland from 1973-1975.  Correia Art Glass spearheaded the Art Glass Movement of the 1970s. 

It is in very good condition with no cracks or repairs.  A great find.
