This is a large Oval shaped solid opal cab. from Australia.  Part of a vintage collection of Opals I have had for many years.

This large stone is perfect for a ring or pendant in the 12x10 mm range.  The shape and size are excellent for any jewelry item.

The stone 1.92 carats and has full actual dimensions of 11.9x10x2.8 mm.    Flat back, perfect for any mounting.

This is a large stone, with a whitish  pink background that is filled with a broad range of color play (greens and aquas and pinks).   Put in the right mounting it will make a stunning piece of jewelry.  The photos were taken in natural daylight and the camera  is picking  up the colors you would see in your piece of jewelry.
