This exceptional piece of 19th-century jewelry is a high-karat "Fringe" or "Festoon" necklace, characterized by its graduated teardrop silhouette and hand-wrought goldwork. Lacking commercial hallmarks but verified via X-ray at a 17-Karat purity (approximately 70.8% gold), the necklace represents a rare regional standard typical of master goldsmiths in Spain, Portugal, or the Mediterranean during the Late Victorian era. Detailed Specifications • The Goldwork & Construction: • Purity: Solid 17K yellow gold, a non-standard antique alloy verified by X-ray fluorescence. • Technique: Features five graduated drops, each framed in a meticulous double-twisted "cannetille" rope border. • Chain: A hand-finished "Bean" or "Gucci" style link chain, exhibiting the slight irregularities indicative of hand-soldered 19th-century craftsmanship. • The Gemstones: • Variety: Five natural Imperial Amethysts, chosen for their deep, saturated purple hues. • Cut: Pear-shaped (teardrop) faceted cuts, displaying the "mixed" faceting styles common before modern precision machinery. • Authenticity: Macro-inspection reveals distinct natural color zoning and growth bands, confirming the stones are of earth-mined origin. • Settings: Executed in "A Jour" (open-back) bezels, an architectural choice designed to allow maximum light transparency through the amethyst crystals. Note on Rarity: The combination of natural, zoned amethysts and a verified 17K regional purity makes this a "connoisseur’s piece."
