I don't know, but I have what looks like a very old sterling silver pin. It is only marked SGW. Wish I knew!
In jewelry, "SGW" typically stands for "Synthetic Gemstone Weight." This term refers to the weight of a synthetic gemstone, which is a man-made stone designed to mimic the appearance and properties of natural gemstones. It is important for consumers to be aware of this designation, as synthetic gemstones can vary in value compared to their natural counterparts.

Wow. I'd rather buy a 42 inch Sony Grand Wega! A PS3 and a '42 SGW at the same price? I'd go for the '42 SGW. It's at the same price, but you better take the better value.
