This is a fabulous vintage celluloid and rhinestone hair comb or ornament in faux tortoise shell and amber rhinestones. These elaborate combs became popular in the Victorian era and continued to be worn through the early 20th century. This one is from the latter part of that time frame. It is a lacy fan shape and rather large. It is nicer than the pictures show - the rhinestones are very bright.
It measures 6 inches by 6 1/2 inches. It is in very nice condition. All of the rhinestones are present and very clear and bright. There is some light scratching and wear to the surface of the celluloid.
