I bought this for my (now ex) fiance, and had our names engraved in it so I cannot even return the item.. so I figured I would at least get the fraction of the cost back at a jeweler that buys scrap gold. they tested it with an electrical probe and said it was maximum 8k, not 10k. so I took it to another jeweler and they performed multiple tests and said that it wasn't even real gold and if it was, it was not enough gold in the ring to fall under a purchasable carat. WOW. and the weight of the ring is 4.8 grams NOT 5 GRAMS!
