Hole Saws

Hole Saws
Hole Saws
can a hole be drilled through a large gemstone without cracking or shattering it?

if done with lubrication/coolant & a Diamond Bit/Hole Saw (im now sure which) could a hole be drilled in a gemstone like a ruby, emerald, or topaz without cracking or shattering it?

Yes. In fact drilling the hole is not even too hard to do with the right Power Tools. You an even drill through a diamond with a diamond Drill Bit, but you may have to replace the bit frequently. Rock drills use a fine oil or water with a constant wash to remove the cuttings. (Water is a very good lubricant for many applications.)

But the resulting life saver-like gem will be extremely vulnerable and easy to break. Having a hard scratch resistant surface does not mean the gem also has high structural strength and resistance to fracture or cleavage. Diamonds used to be worked by breaking them with tiny chisels. Your expensive live savers will be pretty, unusual but easily broken It's worth doing, I think. but be careful how you wear and display it.
