Assorted Vintage-Style Costume Jewelry with Turquoise-Colored Pendant and Faux Pearl Strands

This item appears to be a collection of various jewelry pieces, predominantly featuring strands of simulated pearls and a notable pendant. The main focal point is a large, ornate pendant with a central, irregularly shaped cabochon of bright turquoise-colored material. The setting for this stone is dark, possibly oxidized sterling silver or pewter, featuring intricate scrollwork or filigree surrounding the turquoise. The design of the metalwork suggests a vintage or antique aesthetic, possibly in an Art Nouveau or Arts and Crafts style, though without clearer markings, an exact period is difficult to ascertain. The back of the pendant is not visible, so identifying manufacturing details like maker's marks is not possible. Connected to the pendant, or in close proximity, is a robust, possibly silver-toned chain (visible in the upper left of the image). A multitude of pearl strands dominate the right side of the image, appearing to be faux pearls due to their uniform size, shape, and luster. They are consistent in color, a classic creamy white, strung together. Some strands show a slightly higher luster than others, but overall, they present as costume jewelry. There are no visible chips, cracks, or significant abrasions on the pearls. The metal findings for the pearl strands are not visible, making it hard to assess their type or quality. The overall condition of the pieces appears good, with no obvious damage or missing components. The darkened patina on the pendant suggests age or intentional antiquing. This ensemble would likely be considered costume jewelry, possibly vintage, intended for decorative rather than intrinsic value based on precious materials.
