This Egyptian turquoise round cabochon ranges from medium to deep turquoise-blue and features veins of rich black matrix that vary widely from stone to stone, making each stone unique. Turquoise looks great in silver and other white-metal settings and is best suited to earrings, brooches, pendants and other jewelry styles that are less subject to damage from daily wear.
Sourced from Egypt, this turquoise features a saturated color and displays quite a bit of dark matrix that creates high contrast and unique patterning. Turquoise is one of the birthstones for December.
Turquoise is a soft, opaque gemstone that takes a good polish. Its sky blue color comes from the presence of copper; green tones are provided by iron traces. The veining in turquoise is due to natural inclusions or oxide stains within the stone. Natural turquoise is untreated, chemically or otherwise. Treatments for turquoise include electrochemical enhancement to improve color and stabilization with resin to darken and harden the stone. Individual types of turquoise are usually named according to their source.
