This product has a high luster, there were absolutely no visible defects and the 10mm size is really nice.  These are simple and elegant earrings I purchased for my lady for casual and dress-up events.  Best of all they are made in the USA and that gives me a great sense of satisfaction in a world where not much is made here in the good Ole' US.  A solid product, a great gift.  Give a pair of these earrings to your special lady and you won't regret it.
