VNTG carved Malachite mask with 26" handmade chain

This incredible hand carved malachite mask pendant is (as I have been told )circa 1940's Mexico. The master stone carver used the green malachite swirls to bring out the facial features, and hand forged link chain is perfectly matched to show off the pendant treasure. The makers initials are on the back, 'LG'. Pendant measures 3.75" at the longest point and the chain is 26", and the total weight is 265.4 grams.
