Diamonique Round-Cut Sterling Silver Stud Earrings

This item is a pair of classic round brilliant-cut stud earrings presented in a black velvet-lined presentation box. The earrings feature large, colorless simulated diamonds, likely cubic zirconia given the prominent 'Diamonique' branding on the interior lid. The stones are secured in multi-prong white metal settings, which are identified as 'STERLING' by a physical tag included within the case. The presentation box is a standard rectangular hinged jeweler's case with a black exterior and a gold-stamped logo on the inner satin lining. The stones display high brilliance and fire, characteristic of lab-created simulants. Regarding condition, the box shows significant dust, surface debris, and lint over the velvet flocking, suggesting long-term storage or neglect. A silver-colored 'STERLING' sticker is adhered to the bottom right of the interior tray. No visible chips are apparent on the stones from this angle, but the metal settings may require cleaning to remove tarnish typical of sterling silver. These pieces likely date from the late 20th to early 21st century and represent high-quality costume jewelry meant to mimic fine diamond studs.

I have examined the images of these Diamonique round-cut stud earrings. The earrings are identified as sterling silver via the prominent 'STERLING' adhesive tag within the case, and they feature large, round brilliant-cut stones typical of the QVC-exclusive Diamonique brand, which utilizes high-quality cubic zirconia (CZ) simulants. The stones exhibit significant fire and brilliance, consistent with well-cut CZ, and appear to be approximately 2.0 to 3.0 carats in total weight based on visual scale against the box hardware. The condition of the set is fair to good. While the stones themselves appear intact without visible chipping, the presentation box shows significant accumulation of lint and dust, suggesting long-term storage without use. The sterling silver settings likely exhibit tarnish, a common occurrence with vintage sterling fashion jewelry, though this is easily remediable with polishing. The secondary market for Diamonique is active but saturated. These pieces are valued as high-quality costume jewelry rather than fine jewelry. The value is derived primarily from the wearability and the sterling silver content, rather than intrinsic gemstone value. Comparable sales for boxed Diamonique stud sets generally fall in the $30 range, with pristine examples reaching slightly higher. Without physical inspection, I cannot confirm the tightness of the prongs or the exact carat weight, nor can I verify the specific findings (butterfly backs) are original. However, assuming the metal integrity is sound, the estimated value reflects their status as desirable, classic fashion staples.
