A natural opal formed and faceted as a freeform cabochon. This opal is Australian, it is a natural opal that is untreated. The ct is unknown as it is mounted but including the sterling silver mount, this piece is 3 grams. This opal as it is natural has various features and blemishes which occur naturally and the back of the pendant is left open so that the owner can see the natural brown host rock where the opal material grew. The mount of this piece was created for this specific piece. The bale of this pendant is large and it has "ST . SIL" for sterling silver on it.

Very much a unisex piece, this piece has that timeless styling that suits it for male and female tastes, its basic, minimalist styling lets the gem do the talking.
