This stunning, feminine necklace makes me think of a diamond snowflake. It would be a perfect something old for the Bride! As was done in the Edwardian period the top of mount is platinum & bottom portion is gold. The center collar mounted stone is a European cut. The mount's exterior half circles each contain 7 prong mounted rose cuts. The 4 diamond shapes centered at the half circles each contain 1 prong mounted rose cut. The 4 center leaf patterns each contain 3 prong mounted rose cuts. And the bail contains 6 prong mounted single cuts. Total diamond caret weight is 1/2Ct or more. It is very difficult to measure weight on rose cuts & this pendent contains 44 rose cut diamonds. We believe this to have been a pin in 1910 & someone in the next 20 years or so had the pinback professionally removed & a bail created in the Edwardian style of combined platinum & gold. The platinum chain is an older chain used from about 1910 to 1940. The clasp on the chain is marked PT950 which is European for platinum. We believe the pin to have been originally European in origin as there is a 18CT mark on backside. We guarantee the top to be platinum as we have tested. It is not unusual to find Grandmother's pins turned into necklaces later in life. This was done very professionally & with quality work! The pendent is 1 1/8" wide x 1 3/8 tall (measurement includes bail). The chain stretched out is 16" long. A beautiful pendent with a very stylish look!
