The color of these stones remind me of Kalamalka lake, just over the hill from where I live. It’s one of the few Marled lakes in the world and always makes me stop in appreciation. I’ve used a tube set cubic zirconia as one of the anchor points to hold the stone in place along with three rustic claws. They are mirror images of each other and hang on a sterling silver ear hook. They measure 2cm for the top of the loop to the bottom of the stone.
