NWT Moonstone Crystal Stone Irregular Shape Necklace on Cord Handmade Hand Made Stone: Moonstone Rope Wire: 45cm+5cm extender / 17 in+2.5 in extender Pendant Size: 2 x 1.5 cm (widest part) Pretty minimalistic design. Delicately hued natural stone. The name moonstone derives from the stone's characteristic visual effect, called adularescence which produces a milky, bluish interior light. This effect is caused by light diffraction through alternating layers of orthoclast and albite within the stone. The diffracted light varies from white to blue, depending on the thinness of the albite layers. Size and color will vary slightly since this a natural stone. Serious questions only please.
