| Hi Opera,
The Mikimoto company is a pearl design house. They do not grow the cultured pearls they are selling themselves. If the setting of the pendant has a very small bail or overall too little goldwork to put a hallmark on, the hallmark is on the chain otherwise the hallmark should be on the pendant's goldwork itself. The value of your Mikimoto piece is defined largely by the paperwork and patented design. The cultured pearl itself is only a secondary value aspect.
