i guess i shouldn't have done that.
i mentioned this at craft boston when i was speaking with bree richey designs, and they shared some most useful information on how to fix my mistake, without sending it to a jeweler or buying fancy supplies.
i cut off a sliver and went to work. brush, brush, brush.
i tried taking before and after pictures, but wasn't able to capture the difference. however, i can definitely tell the difference in person. they aren't quite as beautiful as they were in their original state, but they are much improved.
