What a wonderful Matl / Matilde Poulat ring this is. The size is approximately an 8.5 currently and it is capable of being sized by an experienced silver smith. The face front is 1 1/8in. x 1 1/8in. It is deep, being one half inch up from the finger. The weight is 16 grams heavy and it is one of the largest Matl rings that I have held. The turquoise is blue to greens of color and the coral is deep red with a very clear amethyst cabochon centering the piece. The birds are with full tail displayed and quite different than the regular doves that earmark her work. The hallmark is Matl, Mexico and 925 and it is a pre-1960 masterpiece wrought when Matilde was alive. This ring is not just rare it is SUPER rare and a definite choice for a Matl collector.
