Alexander,

For sure, good deals can be had but do educate yourself well before you make that purchase. There’s a lot involved in buying a stone and there are those who will take advantage of the unwary, too. It also doesn’t hurt to know your jeweler but as a first time customer you don’t have that luxury so be prepared with the knowledge regarding diamonds, and particularly the three Cs of diamonds along with a good idea of what you might buy and pay for at home so you can make your own comparisons wisely. Another suggestion is to be certain the store you're dealing with has a US connection in the event you need any kind of servicing after the fact of your purchase.
