Inconsistencies between a case material declaration and other markings raise immediate concerns about authenticity.
-
Karat Designations
The presence of karat designations (e.g., 14K, 18K) indicates the proportion of pure gold within the case’s alloy. These markings are crucial, offering verifiable evidence of the gold content. For instance, if a case is marked “18K,” it should contain 75% pure gold. Discrepancies between this designation and assay office hallmarks are indicators of potential misrepresentation. Absence of a karat designation might suggest a gold-filled or plated construction rather than solid gold.
-
“Solid Gold” or Equivalent Markings
Some cases feature explicit terms like “Solid Gold” or their equivalents in other languages (e.g., “Or Massif”). These direct declarations assert the case is constructed entirely of a gold alloy, as opposed to being plated or filled. A marking of “Solid Gold” without supporting hallmarks warrants careful scrutiny, particularly microscopic examination to confirm the absence of plating or layering.
-
Absence of Material Declarations
The absence of any material declaration is also significant. While not inherently indicative of fraud, it necessitates further investigation. A case lacking material indicators might be of a lower gold purity than assumed, or it could have had original markings worn away over time. Detailed assessment, including metal testing, becomes essential in these scenarios to ascertain the true composition.
-
Material Markings in Relation to Wear
The condition of the material markings must be considered in conjunction with the overall wear and tear of the case. Clear, crisp markings on a heavily worn case may suggest recasing or later stamping. Conversely, faded or partially obscured markings on a well-preserved case are more likely to be original. The correlation between the markings and the case’s condition assists in determining the authenticity and originality of the declaration.
