Untreated gemstones are natural gemstones that are not altered or enhanced in any way. Nafco Gems takes enhancement disclosure seriously and guarantees that our untreated gemstones in this section have had no enhancements. These natural untreated gems remain in the same form as when they came from the earth other than cutting and polishing. These untreated gemstones will have an "N" symbol in the details or description on our website, API and documentation. For more information on gemstone treatments, disclosure etc. please see our gemstone enhancements guide.
