The gold pen is a 144 Solid Gold with 18kt overlay from the early to mid-1990s; later solid-gold models show a herringbone pattern of yellow and white gold, the gold layer is thin and the material value moderate, but the models are comparatively rare. The lapis rollerball is a 163 Solitaire Ramses II with lapis-lazuli cap and gilded silver body (vermeil). The third piece is a 144 Ramses II whose thin lapis-lazuli cap (frequent defect of the range) had broken and was subsequently sheathed in wood/horn by a third party – an unofficial DIY job, no Montblanc original state.
