Wine goblets as you'd imagine come in all different shapes and sizes; they can be made out of a wide variety of materials ranging from glass and crystal to pewter and wood.
They can be as small as shot glasses or as large a fish bowls, and can even come with inscriptions or painted pieces of art right on the side of them! One great thing about one of today's most popular type - the crystal goblet is that it's now at a very affordable price.
They used to be on par with silver and only for the rich and very wealthy, but you can very easily purchase a set of two online for around 40 dollars.
I personally think these make some of the best gifts for a number of reasons.
Firstly crystal is seen as a glamorous material for things to be made out of; fair enough it's not on par with gold or silver, but it's not too far below - and considering glass is pretty much identical the prices certainly are not.
Giving wine goblets as gifts is also seen as tasteful but more importantly assuming the person you give it to drinks wine they'll actually use it and so it'll be appreciated much more.
This isn't some pointless materialistic gift that'll be in the trash basket after a day or two, it'll be used again and again for years probably.
