Vintage shops Signed AMCO Sterling/Rhodium White Spinel Necklace Set

Product Name: Vintage shops Signed AMCO Sterling/Rhodium White Spinel Necklace Set
This is a beautiful necklace and screw back earrings! Done in sterling silver with a rhodium finish which means it won't tarnish and turn dark. The pendant is a genuine white spinel, along with the stones in the earrings. The set has never been worn, in the original presentation case. This would make a wonderful gift for a special person. Do some research on what the spinel gemstone is. "Based on annual production in carats across the world, a natural spinel is rarer than diamonds of any color, sapphires or rubies." There's a red spinel in the Imperial State Crown of England. The sterling chain measures right around 14 inches. I got an approximate length because the pendant is tied in and didn't shops want to take it apart. Please see all pictures as they are a big part of the description. Any questions please ask me.
