Moonstone: What It Is, What It Means, and How to Wear It

Moonstone is one of those stones people recognize long before they can name it. It is the one with the soft light that seems to drift across the surface as you turn it. Here is what it actually is, where that glow comes from, and what to know before you wear it.

What moonstone is

Moonstone is a feldspar — the same broad mineral family that makes up a large share of the earth’s crust. What makes gem-quality moonstone different is its internal structure: it forms in alternating microscopic layers of two feldspars, usually orthoclase and albite. Those layers are what create the effect everyone responds to.

Where the glow comes from

The floating sheen has a name: adularescence. Light enters the stone, hits those stacked internal layers, and scatters. Because the scattering happens below the surface rather than on it, the light appears to sit inside the stone and move as your angle changes. It is not a polish or a coating — you cannot add it or wear it off. It is structural.

This is also why moonstone photographs poorly and looks far better in person. A still image catches one angle; the stone’s whole appeal is what happens between angles.

The colors

Moonstone is not only white. The ones we work with most often run through:

• White and silver — the classic, with a blue sheen
• Peach — warmer, often with a softer, more golden shimmer
• Gray — sometimes called black moonstone, with a smokier body
• Green — earthier, and lovely against gold

The body color and the sheen are two separate things, which is why a peach moonstone can still throw a cool blue light.

Moonstone as a birthstone

Moonstone is one of the three birthstones for June, alongside pearl and alexandrite. That makes it a natural choice for a June birthday gift, and it pairs well with pearl for exactly that reason — you can combine two June stones in one piece.

The folklore

Moonstone has been linked to the moon across a number of cultures for a very long time, which is where the name comes from. Traditionally it has been associated with intuition, cycles and new beginnings, and it has long been given as a travelers’ stone.

We pass that along as folklore, because that is what it is — a record of what people have believed about this stone, not a claim about what it does. We think the real reason to wear moonstone is simpler: it is beautiful, and no two pieces catch the light the same way.

Caring for moonstone

This is the part worth reading. Moonstone sits at roughly 6 to 6.5 on the Mohs hardness scale, which makes it noticeably softer than quartz or aquamarine. It also has directions of weakness running through it. In practice:

• Keep it away from harder stones in storage, or it will pick up scratches
• Take it off before anything abrasive — gardening, washing up, the gym
• Clean it with a soft cloth and, at most, mild soapy water
• Avoid ultrasonic cleaners entirely
• Put jewelry on after perfume and hairspray, never before

Treated sensibly it will outlast you. Treated like a diamond it will not.
