Note that Lab Created Diamonds have become fairly mainstream. You can buy or order from most full-service jewelers. Disclosure is the most important thing - so long as the jeweler is forthright about what they are selling you, it's all ethical. Also be aware that although a reasonable substitution, lab created diamonds have NO residual value (no trade-in value, no secondary market value).
