|Consider this tips when you want to be sure that you are on the right site of online shopping:|
1. Go from offline to online. First shop retail for shape, color, clarity, size (this only works if you are shopping for diamonds with independent lab reports confirming the store's specifications), then go online comparing like-grading reports for best price. True, this is more time consuming then just firing up your browser and shopping.
2. As mentioned above, look for a good refund policy that offers your money back however you originally paid, not just an exchange, with no restocking fees. And make sure you get a good, trustworthy grading report.
