This has to be one of the most beautiful pieces I have seen. The amethyst is large at 20mm. The drop is 4 1/8 across and 2 1/8 high. Made of heavy silver and weighs 81.8 grams. This older vintage piece is a roomy 18 inches long. This piece is definitely Mexican but is unmarked. Many unmarked of this stature were contest pieces and were not allowed to be hallmarked. If you are a collector this piece is definitely a worthy addition. The condition is excellent with no chips or cracks to the stone. No dents and well cared for. Beautiful piece, just LOOK AT THAT NECKLACE!
