We strongly suggest spending time to ask the questions before making the purchase but you've got to know what questions to ask, here are five:
1. What is the color I want?
2. What shape would I like my stone to be?
3. Is the stone I've chosen lively?
4. Am I excited by it?
5. Can I afford it, does it fit my budget?
Once you've narrowed these top five, you're then ready to examine the stones that fit your request.
