Smokey Quartz Earrings and Necklace

Here's an earring and necklace set made for a woman I work with. She had gotten these three brown stones free in St Martin at one of their jewelry stores. I'm going to say they are smokey quartz but I'm not totally sure. She has already purchased a smokey quartz and goldfilled wire ring from me and wanted some jewelry to go with it. I thought I would use brass wire to keep costs down so instead of making earrings and a pendant, I incorporated the stone into a whole necklace. As an accent color I used some Aquamarine Swarovski crystals. Here is what I came up with and I'm hoping she likes it! She hasn't seen them yet.
