One of the foremost sellers of Waterford Crystal in the world, Houston-based Bering’s is the proud purveyor of one of only six full-scale crystal guitars ever produced by the design house. This one — handmade, mouth-blown and fused by master craftsmen in Waterford City, Ireland — was shaped in the form of a Gibson L-7. Bering’s is selling the one-of-a-kind instrument — yes, the strings do play — for an impressive $30,000. Clearly unique!
