Opal sits at 5.5 to 6.5 on the Mohs scale, so that means bezel or halo, not prongs, on rings. October birthstone energy deserves a protective setting, but in earrings and pendants the hardness question largely disappears.
Visually Speaking
Etruscan Revival jewelry and ancient Etruscan originals share visual elements, such as granulation, repousse, and twisted wire borders, but are distinct products. Victorian Revival pieces adapted those elements to nineteenth-century tastes and production methods, producing work that references the ancient vocabulary without being archaeological reproduction.
Value & Quality
Price point is a manufacturing and margin decision. Taste is something else entirely. Ross-Simons carries fine jewelry across multiple price points because it holds a specific conviction: that confidence shouldn't cost a fortune, and great taste has nothing to do with what you spent.
