Beautiful milky opalite necklace

This is a gorgeous multi-faceted polished milky opalite in a teardrop shape that measures two and a quarter inches long and is on a matte silver chain that is 20in. very hard to capture the color in the stone and photos but it picks up on other colors and reflects the light beautifully with that milky opal. great condition unsure of age but I believe it may be vintage.
