There are many ways to tell glass from semi precious stone beads. EHow has published an article on how to tell glass from semi precious stone beads, which describes how to inspect the sound, texture, bead, and cut of the specimen.
No, emeralds are not hard enough to cut glass. Diamonds cut glass and they are the only gemstone with this capability.
Toughened glass cannot be cut after it has been processed, as it will shatter into small pieces if any attempt is made to cut it. The toughening process puts the glass under high surface compression, making it resistant to cutting.
No. Diamonds cut glass because diamonds are harder than glass. Quartz is not as hard as diamond.
cut glass is just that. The pattern is cut into the glass with an abrasive coated metal wheel and polished. pressed glass is when a hot gob of glass is pressed into a patterned mold. These molds are often patterned like cut glass to produce cheap and widely affordable similes of the much more expensive cut glass.
Faux crystal is normally pressed glass rather than hand cut. You can normally tell by finding the mold seams in the glass.
Feel the bowl with your fingers,, molded glass will feel smooth without any sharp edges. Cut or etched glass will have very sharp edges where the glass has been cut or ground. True cut glass is usually much heavier also because these peices are usually made from thick lead glass.

Diamond is harder than glass, so a diamond will 'mark' glass. Glass-cutting takes place when the worker uses a diamond-tipped tool to mark the glass along the cut line, then applies pressure to the glass on both sides of the mark. Glass-cutting tools are tipped with industrial diamonds, which are 80% of all diamonds mined.
