The Montblanc Meisterstück Solitaire Pure Platinum 950 Classique Ballpoint Pen (model/reference 18025) is one of the most exclusive and extravagant writing instruments ever produced by Montblanc. Introduced in limited quantities during the late 1990s/early 2000s as part of the ultra-premium "Pure Platinum" Solitaire line (now long discontinued and sold out worldwide), this is the solid-platinum counterpart to the famous solid-gold Solitaire models.

Key Features

Material and finish: Entirely crafted from **solid 950 platinum** (hallmarked "950" on the metal; 950/1000 purity, higher than standard sterling silver). The barrel and cap are polished to a mirror-like, cool white-metal sheen that develops a subtle, elegant patina over time. Unlike plated or coated versions, this is **pure massive platinum** throughout — no resin core.

Trim: Contrasting 18K solid yellow gold (750) fittings: clip, three cap rings, middle ring engraved "Montblanc  Meisterstück", and twist mechanism components. This two-tone platinum-with-gold-accent design creates a sophisticated, understated opulence.

Size and shape: Classique size (equivalent to standard Meisterstück 165 ballpoint): approximately 136 to138 mm capped, 125 mm uncapped, around 130 to 135 mm posted. Weight is substantial at ~50 to 60 grams (noticeably heavier than resin or plated models, but balanced and comfortable for daily use).

Cap top: Inlaid **mother-of-pearl Montblanc star emblem** (a premium upgrade over the standard white resin star found on most Meisterstück pens).

Clip and details: Solid 18K gold clip engraved with an individual **serial number** on the clip ring.

Mechanism: Smooth twist-action ballpoint, accepting standard Montblanc ballpoint refills (mystery or giant refills in fine, medium, or broad).

Overall impression: A minimalist masterpiece of precious-metal craftsmanship — sleek, heavy, and timelessly elegant with no guilloché patterns, facets, or engravings on the body (unlike barley, pinstripe, or chevron Solitaire variants). The combination of cool platinum with warm gold accents gives it a modern yet classic luxury feel, perfect as a discreet status symbol.

This pen was never a mass-produced item; production was extremely limited.
