Pink Opal Oval Cabochon

With a range of soft pink colors, this oval natural pink opal cabochon is a beautiful choice for pendant and earring designs. It looks great when set in a bezel mounting for a custom pendant or when combined with an assortment of pastel-color gemstones for more complex matched sets including bracelets and brooches. Without the play of color typical of other opals, natural pink opal is a combination of opal, palygorskite, and chalcedony. It presents a range of soft-pink tones and has been called 'pink Andes opal.' The colors of this gemstone make it beautiful in its own right, and the gem is ideal as an alternative to endangered shell and pink coral. Opal is one of the birthstones for October. Opal is a relatively soft mineral that comprises silicon and water and is characterized by and valued for its display of flashing rainbow colors, referred to as the "play-of-color." There are many different varieties, with colors ranging from white or light gray to brown or red to black. While opal may be found in either sedimentary deposits or in volcanic deposits; the volcanic gemstones tend to be brittle and more fragile than the sedimentary gems.
