Last year I discovered peacock ore, a really pretty and shimmery stone, and became slightly obsessed. I ordered a bunch of it from different sources (mostly eBay and Etsy). As I further researched peacock ore I learned that most peacock ore you come across isn't actually peacock ore, it's Chalcopyrite that has been treated with acid. Real peacock ore is actually Bornite, a copper ore mineral that tarnishes to very shimmery shades of blue and purple. I'm not sure if all the ore I'm using is real peacock ore or not, but for simplicity let's say it is.
Step 1: BoM
Glass vial pendant
Mini screw with loop
Step 2: Crush
All of the peacock ore pieces I have were too big to fit inside the mouth of the vial I used. So I put a couple pieces between paper towel and gently hammered at them until they were the right sizes.
Step 3: Fill
I ended up needing to use a harder paper to keep the tiny pieces from sticking, as I wanted all of the peacock ore, even the dust, inside the pendant. I kept adding pieces until the vial was just about full. You want to leave room for your cork topper.
Step 4: Glue
I added a little epoxy around the sides of the cork and then inserted it into the vial. When it was dry I added the screw.
Step 5: Finishing
The final thing is to add the cord to hang the pendant on. Wait until you are sure the glue is dry/cured before trying to wear the necklace.
