This most unusual heavy triangular crystal bottle is cased with striking swirls of green and white opaque glass mimicking malachite. The bottle is blown and hand cut, faceted, & polished. Probably of Czech origin and dating to the 1920s or 30s. May have originally been intended as a large perfume bottle or to hold powder or bubble bath. Very high quality in both work and materials. Unsigned. Condition is near mint with just a couple of tiny inner rim 'fleabites' that would be caused just by inserting the stopper, but not chips, clouding, stains, scratches, etc. No evidence of any part being reground. The bottle stands 6" high and 4" across.
