Introduction: Drill Holes in Rock for Jewelry
Rock jewelry can be contemporary, minimalist, extravagant, and beautiful. So find that special rock and let's make a necklace, earring, or pendent for jewelry. I've fallen in love with this stuff and would have never worn jewelry normally, but this is super easy and produces specie and unique jewelry.
Step 1: Find That Rock!
Find the rock you want to use. Keep in mind how hard these rocks are, and how susceptible to fissure and cracking they are. River stone are best, and stones with quartz are challenging to drill. I've successfully done granite, but it occasionally explodes in my hands.
Step 2: Drilling Tool
It's best to use diamond tipped burs or hole saw that are small. I picked up a well rated set off amazon, and they work great in my WEN rotary tool. Spin it up to speed and drill away. I use a tapered pointed bit to make the initial indent on both side, and then switch to a longer, thinner bit shown in the next step.
*Wear googles*!!!!! rocks can explode from internal stress
Other options: I have used electric hand drills and wooddrilling bits, but they don't work as well, are not as precise, and break after 0-5 uses. do yourself a favor if you're making more than 1 piece or trying harder stones.
Step 3: Drill the Hole
YOU MUST USE LUBRICANT
Water works fine, no need to get a special drilling oil. You will either explode your rock, break the bit, or both if you don't properly apply a heat absorbing liquid. When drilling, cover the rock in water, and re-dip into the water when you see enough gray material as seen in photo 1. Alternatively, drill in a container of water, but know the spinning bit may spray water around.
Step 4: Finishing the Hole
Use a longer, narrower bit to connect the holes you drilled from both sides. You're done!
Step 5: Enjoy!
You've finished! now throw on a jump ring, or thread it directly onto a string, or however you please! I've made amazing necklaces, earring sets, and other unique jewelry pieces that I will cherish.
