Moonstone, Blue Sheen and Rainbow Moonstone

What creates moonstone’s glow?

Moonstone is a feldspar gemstone known for adularescence: light scattered by microscopic layers creates a floating glow that shifts as the stone moves. In jewellery, “moonstone” and “moonlight stone” may describe the same gem, but product naming varies.

Is rainbow moonstone the same as blue moonstone?

Blue moonstone usually refers to a moonstone with a blue sheen. “Rainbow moonstone” is a trade name often used for a light-coloured variety of labradorite, another feldspar. Its flashes can include more than blue. These names describe appearance or trade usage, so check the stated mineral identity when available.

What determines moonstone jewellery prices?

Stone transparency, the strength and viewing angle of the sheen, clarity and cutting quality influence value. A smooth domed cabochon often shows the glow especially well. In finished jewellery, stone size, metal and setting also contribute to price. Compare stones in different lighting and angles rather than judging by a single photograph; natural variation means pieces may not look identical. For expensive pieces, ask whether the stone is natural, treated or imitation, and request clear gemstone information before purchase.
