Sterling , amethyst & opal whale necklace

this is a very very beautiful pendant it is made of thick solid Sterling silver, perfect amethyst and some of the flashyest natural blue opal iv seen and it is in the shape of a whale tail and mounted on a Italian solid Sterling silver rope chain 18 to 20 inch long . it is very hard to capture the fire in opals with a good camera I my phone is by no means god but what you see in the pictures give no justice to the beauty of this necklace.
