Lydian stones, a type of precious gemstone named after the ancient kingdom of Lydia in modern-day Turkey, is pronounced /ˈlɪdiən stoʊnz/. The word 'Lydian' is pronounced with stress on the first syllable and the 'i' sounds like the vowel in the word 'bit'. The 'o' in 'stones' is pronounced like the vowel in the word 'no'. 'Stones' also ends with a voiced 'z' sound. Overall, the word is easy to spell when written phonetically with proper emphasis on the syllables.
Lydian stones, also known as touchstones or touchstones of gold, are natural stones that were historically used as a reference for testing the purity of gold and silver. These stones derive their name from the ancient civilization of Lydia, located in present-day Turkey, which was renowned for its prosperity and advanced use of gold.
The Lydian stones are typically made of black or dark colored siliceous rocks, such as jasper, basalt, or slate. They contain unique properties that enable artisans and goldsmiths to determine the purity of precious metals through a specific testing method called the touchstone assay. This method involves rubbing the metal under examination against the surface of the stone and evaluating the color and quality of the resulting mark or streak.
The Lydian stones exhibit different reactions to precious metals based on their purity. For example, gold of higher purity leaves a distinct golden-colored mark, while less pure gold or silver may produce a different color or streak. By comparing these marks to standard reference samples or charts, experts can determine the karat value or fineness of the metal being tested.
Although the touchstone assay has been mostly replaced by more modern techniques such as spectrometry, Lydian stones still hold value in certain artistic and historical contexts. They serve as a tangible connection to ancient times, conveying the skill and craftsmanship of past civilizations and their unique understanding of metallurgy.
