What Is Galaxy Jewelry, Really?
Galaxy jewelry is a category of jewelry designed to look like the night sky. What separates real wearable art from disposable trend pieces is what is actually inside: many mass-market galaxy pieces use photographs of nebulae printed on paper and sealed under epoxy.
Kate Koel galaxy jewelry is built differently. Every piece contains real stones: pyrite (sometimes called "fool’s gold" for its metallic shine), obsidian (volcanic glass), and black tourmaline placed by hand alongside Swarovski crystals. No printed images. No mass production. Each piece is unique because each galaxy is arranged by hand.
Gemstones inside catch light from inside the piece the way no surface coating can. When you tilt a hexagon Galaxy earring, the shimmer shifts because it's coming from mineral facets suspended inside the resin, not from a coating on the surface. No two pieces are identical. The pyrite fragments settle differently in every pour. A circle and a hexagon made in the same batch will look related but not the same each one captures a slightly different arrangement of minerals and crystals. That's not a flaw. It's the point.
Pyrite — The Material That Makes This Collection Work.
Pyrite has been called "fool’s gold" for over 400 years because of its metallic shine that resembles real gold. The name comes from the Greek "pyr," meaning "fire" early miners noticed that pyrite throws sparks when struck against steel.
In mineral tradition, pyrite has been carried as a symbol of confidence and steadiness a token, not a magic charm. A piece of jewelry can hold a meaning the wearer chooses to give it: a reminder of an intention, a person, or a step forward. That is where any meaning lives in the wearer’s mind, not in the stone itself. What pyrite does literally is catch the light: irregular hand-crushed fragments in a Kate Koel galaxy piece reflect from different angles, creating the look of distant stars in motion.

Obsidian: Volcanic Glass That Holds the Dark
Obsidian is naturally-occurring volcanic glass, formed when felsic lava cools so quickly that no crystals have time to grow. It has been worked into tools and ornaments for over 700,000 years far longer than gold or silver, and was prized in Aztec, Mayan, and Mesopotamian cultures.
In Kate Koel’s galaxy jewelry, crushed obsidian is what gives the night sky its weight. Many wearers also choose obsidian for what it means to them personally a token of grounding, a reminder to stay steady. Like all stones, that meaning is something the wearer brings to it, not something the stone provides.
Black Tourmaline: The Other Dark Stone in Our Galaxy Pieces
Black tourmaline (mineral name: schorl) is a complex boron silicate that forms in long, striated black crystals. It has been worn for over 2,000 years and was used in ancient Egyptian, Roman, and medieval European jewelry for its deep, unbroken black color.
In Kate Koel’s galaxy jewelry, crushed black tourmaline appears alongside obsidian to deepen the dark of the night sky. Some wearers carry black tourmaline as a personal token of protection or focus a symbol they give meaning to themselves. The pairing of tourmaline with the metallic glint of pyrite is what makes each piece feel layered, like the sky after dark.
How Kate Koel Galaxy Jewelry Is Made
Every piece starts in the studio with raw stone. Pyrite, obsidian, and black tourmaline are crushed into fragments so each piece keeps the irregular geometry that makes a galaxy look real. The fragments are arranged by hand with Swarovski crystal grains and pigment into carefully chosen settings: 14k gold-filled or sterling silver for rings, gold-plated or rhodium-plated brass for pendant frames, surgical steel or precious-metal posts for earrings. Every finish is selected with skin safety in mind. Each piece is then sealed for protection and built for everyday wear.
Because each galaxy is arranged by hand, no two pieces are ever identical. Many wearers say the way their galaxy catches the light feels personal to them a feature, not a flaw, of true handmade work. Each order is made in our Florida studio in 1–3 weeks and shipped with care.
Celestial Jewelry for Everyday Wear, Not Just Special Occasions.
A lot of celestial jewelry is too fragile or too ornate for regular life. Pieces with dangling chains inside the resin, or multiple moving parts, or thin fashion metal settings. Kate's Galaxy pieces are different in two ways.
The resin casing holds everything permanently. The pyrite and crystals are sealed inside clear resin there's nothing that can fall out, tarnish from exposure, or loosen with wear. Statement earrings for when you want the piece to lead. Dainty necklaces for layering.
Stacking rings for building combinations over time. All nickel-free, made for sensitive skin.
The Shapes — Geometry Meets the Cosmos.
The Galaxy Collection comes in nine shapes: hexagon, oval, circle, bar, square, triangle, diamond, heart, and eye. Each shape creates a different visual effect with the same galaxy interior. A hexagon reads modern and architectural strong lines, clean edges, the shape that appears in honeycomb and crystal structure alike. A circle is the most classic shape in jewelry and the most versatile it disappears into any outfit or becomes the focal point depending on size. A triangle earring has an edge to it. A bar necklace pendant is minimal and geometric. A heart is the most personal shape in the collection the galaxy interior makes it feel less expected than a plain heart pendant. Choosing a shape is as personal as choosing a constellation. The same crushed pyrite and crystal interior looks completely different depending on the frame around it.
Space Earrings, Necklaces, Bracelets, and Rings.
The Galaxy Collection covers every wearable category. Statement earrings like the Statement Galaxy Round Earrings and Dangling Diamond Galaxy Earrings for when the piece leads the outfit. Dainty necklaces the Dainty Round Galaxy Necklace, Galaxy Bar Necklace, Galaxy Eclipse Necklace for layering or wearing alone. The Disc Chain Round Galaxy Bracelet for wrist stacking. Rings including the Galaxy Planet Stamped Ring. If you're looking for space earrings that hold up to everyday wear, the studs (Hexagon Galaxy Stud Earrings, Galaxy Small Heart Stud Earrings) are the lightest options. The dangling styles are lightweight too resin is one of the lightest jewelry materials but have more visual presence. For a galaxy necklace, the Eclipse and Bar styles are the most wearable with different necklines. Everything in the collection is designed to work as a set or separately. The hexagon earring and bar necklace together are a natural combination. So are the round studs with the disc chain bracelet.
14k Gold Filled Rings Built to Last.
Most of the Galaxy Collection Rings are made in 14k Gold Filled. Gold filled is defined by US federal law: the gold layer must be at least 1/20th (5%) of the total metal weight, mechanically bonded to a base metal core under heat and pressure. This is categorically different from gold plating, gold dipping, or gold-tone finishes, which deposit only microns of gold that wear away in months. Gold filled holds its color through years of regular wear, including contact with water, sweat, and skincare. It's the same standard used in heirloom jewelry that lasts decades. For gold filled earrings and necklaces, this matters: you're getting a piece you can wear daily without watching it fade. Selected pieces are available in 925 Sterling Silver 92.5% pure silver. All settings across the collection are nickel-free. Safe for sensitive skin and metal allergies.
