[header] How to buy organic gem jewelry [title] Buy from a reliable jeweler. [step] Pearls are highly valuable and desirable enough to appear in just about any jeweler's stock. A chain store jeweler is a reliable source, but you may not always get the biggest selection or the lowest cost. 
You can buy from smaller, family-owned jewelers or only for a better selection and price, but you need to do your homework on these sources first. Check reviews, ask if the jeweler is certified by an official gemological organization, and make sure that there are no complaints filed against the company.
