I think the stones are faux alexandrite but I´ve heard this called tanzanite. These faceted stones have the alexandrite characteristic of changing from purple to blue, depending on the light. The earrings are screwback. The brooch has a 1950s or early 60s mark, "MC" in a circle with "TAXCO," and a separate Eagle 3. These are very well-made with good weight and the nice detail of open settings under the stones to show them off. A dramatic, gorgeous set! $ 295.00 US (Requires Cookies)   .: Site by Virgo Media :.
