Gemologica.com is the worst company, especially regarding customer service! TERRIBLE customer service. I'm not the type that is hard to please or who writes reviews but this called for it and I had to warn others. They have no phone number so you fill out the online form and get an email response from the rudest individual, named Judy. GOOD LUCK to anyone who decides to roll the dice with them and don't expect friendly service either. See for yourself. I'd never order from them again nor would I ever recommend them!
