5. Mark the Drilling Point: Use a fine-tipped permanent marker to accurately mark the desired drilling location.
6. Protect the Gemstone: Cover the gemstone with a thin layer of masking tape or wax to protect its surface from scratches.
Drilling Technique
7. Start Drilling: Begin drilling at a low speed and gradually increase it as the bit enters the gemstone.
8. Apply Pressure: Apply gentle, even pressure to the drill bit while keeping it perpendicular to the gemstone surface.
9. Monitor Temperature: Frequently check the temperature of the bit and gemstone to prevent overheating and damage.
Finishing Touches
10. Remove the Bit: Once the hole is complete, carefully remove the drill bit by slowly reversing the drill.
11. Clean the Hole: Use a soft brush or compressed air to remove any debris from the hole.
12. Polish the Gemstone: If desired, polish the gemstone around the drilled hole to enhance its appearance.
Safety Precautions
13. Wear Protective Gear: Always wear safety glasses, gloves, and a dust mask when drilling gemstones.
14. Use a Water Drip: Install a water drip system to keep the bit and gemstone cool and prevent dust inhalation.
15. Handle with Care: Gemstones are delicate, so handle them with utmost care throughout the process.
