This is a lovely Blue Opal necklace

Blue opal is a variety of the gemstone opal that comes in shades of blue and blue-green. Note that the term “blue opal” sometimes refers to a mostly opaque, teal-colored variety of common opal found in Peru.

Like any gemstone out there, opals are wonderful tools for spiritual healing. With their symbolic ocean hues, blue opal possesses a few metaphysical abilities of its own.
