My aunt went to stt about 2 weeks ago and she purchased green diamond stud earings very expensive. She is 82 and was told they are natural and very high quality. Well upon inspection they were something else color enhanced not worth even half what she paid, the woman who says she owns the store Kim stated "no refunds" after they told her 30 day warranty. Bad store. Also found out they used to be called Spectrum jewelers also bad reviews. Unsatisfied and angry.
