Abstracta Square Stacking bands
Abstracta Square Stacking Ring
The Abstracta Square Stacking Rings have a unique ridged, sort of striped texture and are made in sterling silver and 14k yellow gold. The bands come in two widths – one is narrow and one a bit wider. The texture on each square band is made by hand with a goldsmithing hammer, so that each ring is unique. This band looks great with other rings or by itself. Style number S02-ASQ in sterling silver and S02-ASQ14 in gold.
