Here is another of my petite sized necklaces.It is a perfect size for everyday wear. This beautiful Black Lace Agate stone is 23.45mm x 17.3mm. I have set it using 20 gauge sterling silver as the backplate. Total outside size from top of hanging loop to bottom is about 1 1/4". The width is a smidge over 3/4". I have added a nice, diamond shaped linked 18" sterling silver chain. I have also added a corrugated sterling silver bead and two 4mm Red Jasper beads in the back near the infinity style lobster clasp. All metal is oxidized sterling silver or fine silver.
