There are many great sports rivalries in the world, but where I grew up, we didn't have Red Sox vs Yankees or Duke vs Carolina...we had Clemson vs. Carolina (USC that is). I've done some USC colored jewelry before, but here is some jewelry in a Clemson University theme - with lots of orange and purple - that I made recently:
Please email me at diana dot ferry at dcelestine dot com for pricing, as I don't believe I have any Clemson jewelry on my web site (http://www.dcelestine.com). The jewelry is pretty affordable, though, ranging from $15 to $36.
