Most fashion jewelry manufacturers use silver or brass as a base or core metal. We had used both for many years and both are good; but, as a fashion jewelry manufacturer, we discovered that Shavonne's exclusive jeweler's bronze was superior in all ways for beauty and wear ability. Even though its initial cost is greater, cost has never been our prime concern. Customer satisfaction is--and always has been--our greatest concern.
Natural stones can and will have many different shades, from darker to lighter. In fact, all natural stones except perfect blue-white diamonds have these variations.
Cubic zirconia stones, too, have these color variations due to the highly sophisticated process used to create them--vacuum induction. In this manufacturing process, a large free-form piece of cubic zirconia is created as the various quality ingredients necessary for cz are electronically injected into a vacuum.
For stones other than clear diamond czs (e.g., ruby, sapphire, emerald, peridot, or tanzanite), permanent coloring is also perfectly blended at this time, meaning the color is permanently ingrained throughout the stone--not just on the surface. Many lower-quality cubic zirconia stones only have a coloring on the surface which will lose brilliance over time, but Shavonne uses only the highest-quality cz stones, Russian formula, in our fashion jewelry.
However, color tends to be lighter on the extremities of the uncut, free-form cz and darker towards the center. Typically, larger stones are cut from the center of the cubic zirconia, and smaller stones are cut from the extremities of the stones.
Different renderings of cubic zirconia stones have slightly different shades, and stones cut from different locations on the newly-created free-form cz will have slightly different shades. So, the cubic zirconia stone you get will have a beautiful, realistic ruby, sapphire, emerald, tanzanite, or peridot appearance but its very own unique shade.
With the exception of our replica watches and jewelry that contains certain natural stones (such as jade, pearls, coral, etc.) this is how we beautifully maintain tens of thousands of pieces of Shavonne jewelry:
The result is beautiful. All water (except certain bottled waters) contains many minerals that, when allowed to air dry, will deposit a fine mineral residue on the surface that eventually dulls that surface of the jewelry. By evaporating all moisture from the jewelry immediately with your hair dryer you also dispose of the mineral dulling problem. The result is a return to its natural beauty.
