Location of discovery: Nacozari Copper Mine, Sonora, Mexico.
Origin: Direct mine source.
Gemologist / Geologist Notes: Naco turquoise is professionally stabilized. Not altered, colored, etc. Naco turquoise was found just across the border south of Bisbee. The rare, darker blue specimens are often compared to Bisbee Blue, although rarer in quantity.Condition Notes: As seen in pictures. Most specimens not professionally cleaned so dirt may be present. Some specimens may be stabilized without our knowledge, as some processes are very hard to detect. Some specimens may have odors from long-term storage, old mounting glue, tags or mouthing material attached. Some specimens may not sit upright as seen in pictures and may require a stand or other propping device. Saw marks may be present on "semi-polished" rough or specimens. Images: All specimens are photographed with bright, natural sunlight at 5000K to 5500K and checked for correct color with a calibrated monitor. Specimens viewed in poor lighting or non-daylight illumination sources may not appear as in the photographs. Some specimens (as noted in the description) may be seen wet or damp to show lapidary potential. In such instances, received item(s) may appear duller until professionally polished.Warranty: We do our best to accurately describe our mineral specimens or rough. However, as it is with most minerals, it's impossible to determine the exact interior structure or content, so we cannot warranty or refund specimens or rough used for lapidary work. Such work is done at your own risk. Returns and Terms: If you are not happy with any purchase, please contact us first before filing an claim and we will happy to refund your purchase. We strive to describe each specimen as accurately as possible, but it's always possible that we may miss something as an honest mistake, as some specimens are very complex and we all have varying degrees of acceptance. Specimens that have been altered (polished, broken, cut, etc.) by the buyer cannot be returned for a refund.
