This is a lovingly hand crafted 17" to 19 3/4" adjustable necklace and earring set. I have used some pretty large link chain and added some polished Agate stones in colors of clear, smoky and red orange mix. The chains link are 17mm x 11mm and the stones range around 14mm on the necklace and the earring stones are about 20mm long. The matching earrings are about 2 1/2" long including the 14K gold plated closed hooks. 5% Goods and Service Sales tax is required within Canada. Check out my other items..
