Maker

Material
Silver-plated brass (Metale Blanc or Nickel Silver base). The visible item is 'Qualité Garantie' silver plate, likely electroplated (EPNS) over a copper or brass alloy frame for durability.
Dimensions
Estimated height 8-10 cm; diameter 3.5-4.5 cm. Estimated weight 150-250 grams depending on lens density and internal metal thickness.
Description
A refined example of Belle Époque optical luxury, this Iris de Paris monocular served as an essential accessory for the theatre and opera-going elite. The silver-plated exterior features an elegant central crest that emphasizes its Parisian pedigree. Its compact size and ornate detailing reflect a period where scientific utility was seamlessly merged with high fashion, designed to be seen in the hands of the wealthy as much as it was used to see the stage.
Key Features
Prominent 'Iris de Paris' branding, 'Qualité Garantie' stamp, beaded bezel detailing, and a classic French winged cartouche design.
Material & Composition
Silver-plated brass (Metale Blanc or Nickel Silver base). The visible item is 'Qualité Garantie' silver plate, likely electroplated (EPNS) over a copper or brass alloy frame for durability.
Finish & Decoration
High-polished mirror finish with machine-stamped and hand-touched decorative engraving. Features a central cartouche with feathered acanthus leaf flourishes, a fleur-de-lis top, and a beaded or gadroon border around the base of the eyepiece.
Hallmarks & Stamps
Engraved trade mark: 'MARQUE IRIS DE PARIS' centered in a cartouche, with 'QUALITE GARANTIE' (Guaranteed Quality) below. This is a commercial branding stamp rather than a government silver hallmark.
Construction Details
Machine-turned cylindrical body with applied decorative bands. The eyepiece is threaded (screw-on) for lens maintenance. The engraving is die-stamped, a common feature of French industrial luxury goods of this period.
Functional Features
Telescopic focusing mechanism (suggested by the upper ridge), optical glass lens inserts, and a beaded grip at the base for tactile precision while adjusting focus.
Handle & Grip Details
Knurled or beaded lower ring for grip; the main body is smooth silver plate. Some models featured a fold-out handle (lorgnette style), though this specimen appears to be a handheld monocular.
Craftsmanship Details
High-quality industrial craftsmanship. The precision of the threading and the clarity of the engraved 'Marque' indicate a high-end workshop production rather than mass-market imitation.
Authentication Indicators
The branding is consistent with known Iris de Paris optical sets. The wear patterns on the silver plating show the brassy undertones typical of genuine antique silver-on-brass construction.
Origin & Manufacturing
Paris, France. Manufactured in the specialized optical workshops of the Parisian district, which was the global center for luxury opera glasses during the late 19th century.
Era & Period
Belle Époque / Late Victorian (circa 1890-1915). Characterized by the use of traditional French decorative motifs (fleur-de-lis) on emerging modern consumer technology.
Age Estimate
Circa 1900. Derived from the font style of the branding, the 'Qualité Garantie' phrasing common in the Pre-WWI era, and the Neo-Rococo framing of the cartouche.
Cultural Significance
Represents the height of French 'Art de Vivre.' Use of such optics was a social ritual in the 19th-century opera house, denoting wealth and a sophisticated interest in the performing arts.
Condition Notes
Very Good. Shows light surface scratches and minor tarnish consistent with age (patina). The plating appears mostly intact, though some micro-pitting is visible near the beaded base.
Value Estimate
Market value $100 - $250 USD. Value is highest when lenses are clear and silver plating is not 'worn through' to the base metal.
Care & Maintenance
Gently polish with a soft microfiber cloth; avoid abrasive dips which can strip the silver plating. Use a lens-specific cleaner for the glass. Store in a dry environment to prevent 'clouding' of the internal optics.

Interesting Facts
Iris de Paris was a frequent competitor to Lemaire and Chevalier; these items were often sold in velvet-lined morocco leather cases and were popular gifts for young women entering high society.
