This lovely Edwardian bracelet dates to the 1930s. Features a large color change synthetic stone that is lavender purple in normal daylight, with incandescent slightly deeper purple. Yet under lighting with natural daylight bulbs it turns a pretty light topaz blue. I haven't viewed it yet under other light conditions so it could have other color changes as well. How fun is that, eyes will be on it constantly to see the changes. Synthetic Alexandrite has been around since the early 1900's.
The metal has a gold wash that is worn in the high areas and silver underneath. It's a hinged bangle with a double button push clasp and long slide for safety against loss. To each side of the stone is a bi-gold colored flower of green leaves and pink rose. Hard metal that is unmarked other than the makers mark. Manufactured by A.I. Lindroth Company from Attleboro, MA. Marked ALLCO. ALLCO made bracelets, they seem to have been a longer-lived and more varied company, selling all types of jewelry. This company appears to have been in business between 1896 and 1937 according to some resources but does have some mention of jewelry made as late as the 1940s. For a wrist up to 6-1/2 inches. The bracelet measures 1/2 inches wide and the central area with the stone is 1 x 5/8 inch. Elegant and beautiful on the wrist. Much better than the photos show.
