This is a luxurious ring featuring a natural black opal. The main stone offers a unique and **vibrant play-of-color (blue and green flashes)** that varies with each stone. The color shifts with the angle of light, creating a beautiful effect like stars twinkling in the night sky. The main stone measures approximately 7x9mm and is precisely set in S925 sterling silver. It's a free-size ring available in three colors: white gold, yellow gold, and rose gold. This is a one-of-a-kind piece of jewelry that shines elegantly from every angle. Thank you for looking.
