Antique 18ct White Gold & Platinum .45tcw Diamond & 1.0ct Sapphire Ring in Southampton, Hampshire for sale

This beautiful antique trilogy ring was left to me by my grandma and I hope to sell it to have a memorial for her that the whole family can share. I am unsure of the exact age of this ring but it will be at least 50 years old. The ring size, I believe, is an N. This ring is 18ct white gold with the shank being constructed of platinum and is fully hallmarked. This ring contains two stunning diamonds and one beautiful quality created sapphire. The diamonds are 0.45tcw approx, one is about .20ct and the other about 0.25ct. They are transitional cut diamonds, which are rare these days, and of approximately SI1 clarity. Their colour is about H-I. The centre stone is a 1.0ct quality created sapphire (5.5x5.5x4mm) and is a princess cut. The colour and saturation are very good; a lovely deep blue. This is a beautiful ring of very good quality and is in overall good condition for its age. Please text or email rather than phone as my reception is really poor here.
