Moonstone: light trapped between layers
One piece in the shop is set with rainbow moonstone — The Wandering Moon, a pair of sterling studs, hand-forged and made to order in Nashville. Below: what causes that floating blue glow, why moonstone needs more care than its hardness suggests, and the piece I set it in.
What moonstone actually is
Moonstone is feldspar, the most common mineral group in the earth's crust, but grown in a particular way. As the stone cooled it separated into alternating microscopic layers of two different feldspars, stacked like sheets.
Light hitting those layers scatters between them and comes back as a soft blue-white glow that seems to float just under the surface and move as you tilt the stone. The effect has its own name: adularescence.
"Rainbow moonstone" is properly labradorite rather than true adularia moonstone, and it is the one that throws blue with occasional flashes of other Colors. That is the material in these studs, and I would rather tell you that than let the label do the work.
Why moonstone needs more care than its hardness suggests
Moonstone sits at about 6 to 6.5 on the Mohs scale — respectable, harder than turquoise. But hardness is not the number that matters here.
Feldspar has cleavage: planes along which the crystal will split cleanly if it is struck the wrong way, and moonstone has it in two directions. Which means a moonstone can survive years of ordinary rubbing and then chip from a single knock against a door frame.
So it is a stone that rewards being worn somewhere protected. Earrings, pendants — the inside of a life rather than the outside of it. It is not what I would choose for a ring you wear while moving furniture, and I have set it as studs for exactly that reason.
That is not a flaw. It is a stone that asks for a particular kind of attention and gives back something no hard stone can.

If you want that shift of light in something you can knock about
Moonstone is not the only stone that moves. Tiger's eye does it in gold and is far tougher; lapis gives you depth instead of movement. Same silver, same hands.
How I set it, and why these are studs
With a cleavable stone the setting is protection, not decoration. A stud puts the stone flat against the ear where very little can reach it, and a full bezel wraps the girdle so no edge is left exposed to a knock.
Adularescence is directional, so each stone has to be oriented for the glow to sit face-up rather than sliding off to the side. Set it carelessly and you have a grey stone.
I would rather make a small piece that survives than a large one that doesn't.
Looking after it
Warm water, mild soap, a soft cloth, dried gently.
Never an ultrasonic cleaner and never steam — vibration and cleavage are a bad combination, and heat is worse. No ammonia, no bleach, no supermarket silver dips.
Off before the gym and the pool, and stored where they are not knocking against anything harder.
The silver is meant to darken. If it ever goes further than you want, bring them back — polishing and re-Oxidizing is free, forever, for anything I've made.
Questions I get about moonstone
Why does the glow disappear at some angles?
Because adularescence is directional — light has to enter and leave the layered structure in the right way. Tilt it back and it returns.
Is rainbow moonstone real moonstone?
It is feldspar family, but technically labradorite rather than adularia. It is honestly named in the trade and it is what produces the blue flash.
Is it fragile?
Not soft, but cleavable, which means it chips rather than scratches. Treat it as a piece to be slightly careful with and it will last indefinitely.
Can you make something specific in moonstone?
Yes — commissions start with a conversation, so just submit a commission request And if you’re buying for someone else and aren’t sure of their size, a gift card lets them tell me.
Not every path is meant to be certain — some are only meant to be walked by feel.
The Wandering Moon Studs are handcrafted daily talismans for those who trust their instincts over a map. Each earring features a genuine Rainbow Moonstone cabochon, its milky surface catching flashes of blue adularescence with every turn of the head, secured within a detailed sterling silver crown bezel. Sitting close to the ear on sturdy sterling posts, these compact studs bring quiet, shifting light to your everyday armor — a small reminder that you're exactly where you're supposed to be, even when you don't know where that is yet.
