I was a novice at buying earrings at the time I bought these. I thought the words "black silver" meant that the silver in the mounting was manufactured to be black -- just like you can have yellow gold, white gold, rose gold, etc. What "black silver" actually meant was the the mounting was painted black. After wearing them several times the black started to flake off. By the time a month had gone by, all of the paint had flaked off. The resulting cup, a dull silver in color, looked awful.

There are many other 6mm CZ stones in prong settings for about the same price. I also think the prong setting shows more sparkle than does the cup setting. I would not recommend these earrings to anyone and suggest you look at other CZ earrings here on Amazon.
