1 3/4 inches x 1 3/4 inches. This necklace features a dendritic agate that looks like trees on a snowy day. The presence of iron in the agate when it was molten makes this pattern. It is captured by a bezel of 24K plated glass beads stitched together one by one , and surrounded by lots and lots of tiny natural pearls. The chain is the same gold beads and pearls stitched together and is 1/4 inch wied and the overall length is 16 3/4 inches with 2 inches of chain for longer adjustment and a hook clasp.
