rare and in excellent antique condition Authentic English Georgian paste Riviere Choker necklace! please see photos for description. no missing stones - white diamonds paste and purplish paste -it does not look like amethyst paste, but more of a purple sapphire paste medium light purplish with pink overtones ! Please see last photo near Georgian amethyst paste for a color difference. the necklace approx 15" from end to end and a little under when clasped. all stones sit firmly and no visible damage or heavy wear- just patina and light wear with magnification can be seen. for being so old it is in excellent condition! made in sterling silver. the paste is very sparkly (as with all of the authentic Georgian pastes I ve seen) on the light! the pastes and the links are substantial in size and in the same time comfortable on! amazing collectable necklace!
