VERY GOOD. This Georgian Rococo era Garnet Diamond trilogy ring is in very good antique condition. Iberian jewellery, especially rings, are very hard to find today, being both rare and highly sought-after by antique jewellery lovers everywhere. The Georgian pie-crust setting is a beauty, very snug to the central Garnet which has a plump and smooth peachy button-back setting. The setting on the Garnet does have a couple of scratches to the Gold, to be expected of a ring of this age. Incredibly, his treasure was hand-made by an artisan over 230 years ago! One of the sizeable rose-cut Diamonds has a small chip on the outer edge, but all the gemstones are well-set and have no hint of movement. As the ring has closed-back settings we recommend keeping this ring dry and free from moisture. Although she is robust, it is best to keep her for occasional wear due to its impressive age.
