Its hard to pinpoint the exact colour of alexandrite which is part of its appeal. It will change depending on the lighting and time of day. We think it sits beautifully against rose gold which is why we have chosen this alexandrite coloured cz as the birthstone for June for this charm collection. The 3.5mm crystal is set into rose gold plated sterling silver and hangs from a jump ring fastener. Overall this charm measures 10mm x 4mm x 3mm and weighs 0.3grams.
