Aurora Pearl [WORK]

The PSL (Pearl Science Laboratory of Japan) describes it as such: Aurora Effect is the characteristic phenomena of iridescent color that may appear on the surface of a pearl. They test for this by using a cleverly named "Aurora Viewer", which shines a particular light on the underside of the pearl to reveal if there is visible Aurora. Below are pictures of a Madama Akoya strand showing fantastic "aurora". Top Range white Hanadama will show this effect as well, but it's extremely difficult to photograph.

Yes, they are all authentic cultured pearls. You'll receive a Certificate of Authenticity with every purchase. All of our pearls are grown in either freshwater or saltwater. We source them directly from pearl farms and processors around the world. Each pearl has been through a strict selection process and is chosen individually for its fine quality. We do not sell imitation or fake pearls.

A lifetime. Because our jewellery is made with high quality pearls in solid 18k gold or sterling silver, its beauty can literally last forever as long as you take good care of it. As with all fine jewellery made with high purity precious metals, it's very soft and is subject to bending, denting and scratching. As such, extra care should be taken when handling all fine jewellery. Take it off when you are doing housework, gardening, heavy work or playing sports.

Percina (Cottogaster) aurora is an imperiled species under consideration for listing by the U.S. Fish and Wildlife Service. To better understand habitat use of P. aurora, we studied a related and more abundant Cottogaster species, Percina copelandi, from the Ouachita River, Arkansas. We used a laboratory stream system to examine mesohabitat selection (pools versus riffles) and microhabitat selection (substratum particle size) of P. copelandi over three temperature regimes (summer, spring, and winter). Percina copelandi selected pool habitats over riffles and selected pools with coarse substrata (e.g., cobble) over fine substrata (e.g., gravel). In riffles, P. copelandi selected large substrata during winter and spring but did not show particle size selection during summer. These data, and various published and unpublished field data for P. aurora, suggest that habitat use of P. aurora is also centered around deep runs and pools, with large substrata likely being more important at low water temperatures.
