how much are engagement rings USUALLY ? (average price)

The old rules of "three months salary" for an engagement ring really do not hold true anymore. We see couples pay vastly different amounts for their rings depending on their stage or life and their style. We always recommend that our customers should buy the best quality that they can afford. This may mean a smaller diamond but with a higher colour or cut grade that looks beautiful rather than a larger diamond that is yellow or doesn't sparkle as much. 

You could realistically spend anything on an engagement ring. You could get a beautiful, top quality, fine diamond engagement ring from around $3000 upwards.
