I can't figure out how to post a question. But I have a big problem. I have wanted an Alexandrite since I found out it was my birthstone over 50 years ago. I cannot afford a real one so I ordered on line. I inherited some money because my mom died in December .Well It says on the Chatham web site they turn blue,green in the sunlight. I got the stone last night and couldn't wait for the sun. Well, nothing. It's purplish pink and never turned teal. I am so upset. Please help
