Knotted glass pearl-style necklace in the manner of Camrose & Kross

This item consists of multiple strands of cream-colored, spherical beads that appear consistent with high-quality simulated or glass pearls. The beads exhibit a soft, lustrous sheen and are individually hand-knotted on a white cord, a construction technique typically used to prevent surface abrasion and provide security if the strand breaks. The necklace is shown with a filigree-style silver-toned clasp, featuring decorative openwork consistent with mid-to-late 20th-century costume jewelry designs. The piece is accompanied by printed collateral, including a card bearing the brand name 'Camrose & Kross' and a certificate of authenticity appearing to link the item to their Jacqueline Kennedy collection. The certificate contains text mentioning 'Jacqueline Bouvier Kennedy' and '1917 * 1963', along with a red seal-like graphic. While the branding suggests it is a reproduction modeled after jewelry worn by the former First Lady, these markings and documents are unverified without physical inspection and provenance testing. The overall condition appears excellent with clean cord and consistent nacre-like finish on the beads, though minor surface dust is visible. This attribution is based on the legible collateral and stylistic design, but authenticity of the brand or materials cannot be confirmed from the image.

I have examined the images of this multi-strand glass pearl-style necklace. Based on what I can see, the piece bears markings and collateral consistent with the Jacqueline Kennedy collection by Camrose & Kross. The hand-knotting and silver-toned filigree clasp appear characteristic of this specific line of high-quality costume jewelry. However, I cannot verify the authenticity of the brand or the materials from a photograph alone; a physical inspection would be required to confirm the weight of the glass beads and the integrity of the nacre-like coating. The estimated value of $150 - $250 assumes the attribution to Camrose & Kross is correct, as items from this specific 'JBK' line currently see consistent demand from collectors of historical reproductions. This value is supported by the presence of the original certificate and box, which generally increases the desirability of such commemorative pieces. If the item were found to be a generic 'in the style of' reproduction without the associated branding or documented link to the Kennedy collection, the market value would likely decrease significantly to the $30 - $60 range. Market conditions for mid-to-late 20th-century designer costume jewelry remain stable, with a particular niche for high-end replicas of famous estate jewelry. To establish a more definitive valuation, I recommend an in-person examination by a jewelry specialist to verify the manufacturer's marks on the clasp and to ensure the finish does not show signs of peeling or degradation that would negatively impact the piece's condition rating. Scientific testing of the metal composition would also be necessary to rule out base metal substitutions.
