The amethysts in this necklace are such an intense colour, really stunning. The necklace is not marked but tests to gold of at least 14k by acid method (guaranteed). The hand made flat fancy chain is typical of American pieces of this period. The chain is 6mm wide and the necklace length is just over 15 inches. the amethysts are all original and range in size from 13mm by 10mm to 20mm by 16mm. They are cut slightly rounded on the top which shows the optimum colour. They are also cut nice and deep. The clasp is a box type and is in good condition. Condition is very good, with some natural inclusions to the amethysts visible under close inspection. Late Georgian and American in origin.
