Nature's 1 Jewelry

Saw Subject brand jewelry on display at a store on Fisherman's Wharf, in Monterey, California. The brand seems managed by supplier Wheeler Mfg Co., Inc., out of South Dakota.

Wheeler Manufacturing, Pendant (WMP), #169, a turtle pendant

Note: this seems like it has a lot of similarity to Na Hoku:

Na Hoku "14K Rose Gold Honu (Turtle) Pendant with Pink Mother of Pearl Inlay." (link)
