Will these work with semi precious gemstones?? -sapphire, amethyst, citrine etc

We use these to drill sea glass, tile, and shells. Not sure if they will work on gemstones.

I want to drill a hole on each side of a 1 inch flat marble for a bracelet. what bit di i look for. i saw a video . need a round or conical tip. help

I had best luck making a clamping jig that set in a beaker of water and used a Dremel drill press. The drill is about 1/2 inch long and I had to drill from both ends because a bead was larger than 1/2 inch. I used the pointed cone to get an accurate start and then reamed out with a 1mm drill to complete the hole. Getting the two tunnels to meet in the center is tricky when the drill is too short. Work slow under water. Don J.

Will these work with a Ryobi quick release drill?

These are really a terrible quality... Don't think I have ever successfully used them as they don't even drill glass.

Do they fit dremel 3000 drill?

Yes they will fit a Dremel 3000 (as long as you have the right size collet) however I do not recommend these drills at all for drilling glass (which is what i bought them for) they were completely useless.
