Extremely detailed brooch features the Mayan calendar in the center of a symmetrical design and intricate border. This is marked "Heche in Mexico" (made in Mexico) and has the number 925 engraved for sterling content. It also has the letters/numbers TC-271. This can be worn as a brooch, or with the bale, as a pendant. Condition is fine with no issues at all. This weighs 22 grams and measures 1 1/2 inches in diameter. Fabulous piece!
