This treasures came today from my lovely Armenia. Great artist Manoush made it for me. I fall in love. I can't stop myself looking on it. It made from ammonites (any of a subclass of extinct cephalopods especially abundant in the Mesozoic age that had flat spiral shells with the interior divided by septa into chambers), citrines and silver. Left part of the ring is ammonite and right-different citrines. All this jewels are pure couture.
