NEW INFORMATION LISTED!! This is an unusual Mexican silver necklace to say the least. There are 2 sets of markings and one is the Spratling (some missing but clear) and the line under is DE MEXICO. Please inquire for more pix. These are the marks on page 69 of Spratling Silver: A Field Guide by Goddard. The other mark is on the amethyst drops (in Pix) and they denote made in Mexico City. Vetting consensus (please inquire for info on this)is Spratlings 2nd design phase and the amethyst drops (that Spratling did not use at this time) were rather "added" by subcontracted piece work of Conquistador circa 1950 towards the end of an unfulfilled contractual agreement. Recommended reading pg 67 & 68 of the Goddard's field guide. She notes that only 100 designs are known to be seen and 300 were to be produced. Length is 16.75in and 1.5in wide link and 33.8gms. The stations are SOLID with a repousse ball on the top. We have a most lovely piece that at best is produced not by Spratling and a modified design of Spratling with genuine hallmarks. The price reflects a beautiful treasure. The amethyst bracelet just looks great with the necklace is marked Silver Mexico (not an exact match to the necklace) and weighs 100.1grms. The face of the bracelet is 2.5in wide and this piece is made of giant filigree. There is tarnish to the piece and I thought previously there was a repair but after having an opportunity to see another of this design I see that it is in the making and the large strips of filigree are rather bent with a twist and put together.Condition is better than excellent. A great price for this piece! It Fits a 7in. wrist perfectly. Just, LOOK AT THAT NECKLACE!
