It's important to understand what you are buying. Gem stones all vary significantly and you need to adjust your selection based on purpose, cost, expected out come.In my case I was selecting and very attractive heart shaped stone which once set in a pendent would fall in a specific cost range yet present an attractive picture of luxury without extreme risk e.g loss.
