Are stoppers usually original to the bottle?

Many decanters and scent bottles retain their matching original stoppers, which were ground to fit a specific neck during production. You can often check originality by examining the matching cut patterns and the frosted glass ground seals. Replacement stoppers do occur frequently due to accidental breakage over the decades. A correct fit and consistent glass colour indicate a period-appropriate replacement rather than an original pairing.

What is the difference between crystal and glass?

Crystal contains a specific percentage of metal oxides, traditionally lead oxide, which adds significant weight and density compared to ordinary soda-lime glass. This heavier chemical composition enables artisans to cut sharper facets and achieve greater optical clarity. Under inspection, crystal produces a clear ringing sound when gently tapped and disperses light into spectrum colours more intensely than standard glass.

How do I date a silver mounted bottle?

Sterling silver collars and caps usually carry hallmarks indicating the assay office, date letter, and maker's mark. These stamped symbols provide a precise year of manufacture for the metal mount. The style of the glass body, cutting patterns, and overall form help confirm whether the mount and the bottle were created together or assembled later.
