Turquoise stick pin

This is a small decorative stick pin featuring an oval-shaped turquoise-colored stone set within a metal bezel. The metal setting appears to have a textured, rope-like or milgrain edge surrounding the central cabochon stone. The pin shaft is slender and made of a metallic material extending outward from the back of the setting. The overall physical construction suggests a traditional lapel or tie accessory, possibly dating from the late 19th to mid-20th century based on stylistic conventions, though no specific maker's marks, hallmarks, or stamps are clearly visible in the provided image. The color of the stone is a vibrant blue-green with subtle matrix variations. The piece displays minor surface wear consistent with age and handling, but overall condition details are limited due to the resolution and angle of the photograph. The identification of the materials and period is based purely on visual inspection and remains unverified.

Based on what I can see in the photograph, this stick pin appears to feature an oval turquoise-colored cabochon set in a metal bezel with textured or milgrain detailing, consistent with traditional lapel accessories likely dating from the late 19th to mid-20th century. However, I cannot verify the exact metal composition, stone treatment, or precise age from a photo alone, as visual inspection has severe limitations. The valuation range provided assumes the hypothetical scenario that the materials and period are consistent with this visual assessment. In general market conditions, vintage costume and semi-precious stick pins of this type experience modest demand among collectors of period accessories. If physical inspection reveals the piece to be a modern reproduction, replica, copy, or produced 'in the style of' the period rather than a period piece, the value would likely drop significantly to the $25-50 range. To confirm authenticity, material composition, and any potential maker's marks, an in-person examination by a qualified professional, hallmark verification, and potentially scientific testing of the stone and metal would be required.
