EXCELLENT: A beautiful antique 18ct White Gold Diamond trilogy ring offered in very good antique condition. She is such a looker! With 1 carat of antique natural Diamonds all set in solid Gold, this Art Deco engagement ring has beautiful sparkling Diamonds and secure settings suitable to be worn daily. The ring is stamped with an Art Deco "18CT" stamp but this is not crisp and has either been dulled by the sands of time or was poorly struck when it was made, over 100 years ago. Luckily the Diamonds are in very good condition, with no chips or damage to note and have a beautiful H/I/J colour and Si clarity! If you're looking for a ring to "pop the question" then look no further, she is simply divine!
