    The Akoya pearls are known for their perfectly round and symmetrical shape and mirror-like luster. Akoya pearls are traditionally white and have overtones of either silver, rose, or ivory.

    Blue Akoya pearls are rare because, for years, they have been discarded by the farm owners. The main reason was the free-form baroque shape of these pearls. Besides, most naturally colored blue Akoya pearls lack the required nacre thickness and do not survive for long. Even when they do, you will notice peeling nacre and white nucleus within a few years.

    However, the mindset towards the blue Akoya has changed in recent years, and jewelers are now taking an interest in them. A high-quality blue Akoya can be identified by its deep blue color and intense overtones. They have thick nacre and can be used in jewelry like any other pearl. These pearls are rare to find and considered exceptional.
