Wear them to school pickup or a lunch date, and someone will lean in to ask if those are real flowers. Three tiny pressed flowers rest over crushed black tourmaline and flecks of abalone, delicate up close and rich and dark from a step away.

  • Metal: Gold plated brass frame, nickel and lead free. Steel post with a butterfly back that holds them securely in place. Safe for sensitive ears, comfortable for everyday wear. No green skin.
  • Crystal: Crushed black tourmaline, small abalone shell chips, and three real dried pressed flowers, hand arranged and sealed with glass-like resin. Museum quality, no yellowing.
  • Style: 10mm round stud, about the size of a small blueberry.

14k Gold Filled
Gold filled is not plating. A thick layer of solid 14k gold is bonded to a jeweler's brass core under heat and pressure, so the piece carries about 100 times more gold than a thin flash plate. That is why it holds its color through daily wear instead of rubbing thin at the edges.

925 Sterling Silver
Solid sterling, bright and cool against the skin. I also offer an oxidized finish, a soft blackened patina that deepens the look of a stack and sits beautifully next to your gold pieces.

Signature Crystals
This is the part I also make by hand. Semi-precious gemstones, real dried botanicals, and Swarovski crystals, arranged one at a time and sealed under UV stable resin that stays glass-clear rather than yellowing. Because the elements are natural, no two are ever exactly alike.

Made in My Florida Studio
I make every piece to order in my studio here in Florida. Small differences in flower placement, stone color, or the depth of a crystal are part of the design, not a flaw.

Made for Sensitive Ears and Skin
My fashion studs use surgical steel posts and backs, chosen for ears that react to almost everything else.

Artisan Frames (Pendants and Earrings)
The statement frames are lead free and nickel free brass, finished with a heavy gold plate for a rich, high-shine luster.

Gold filled, vermeil, plated: what's the difference?

It all comes down to how much real gold you're wearing.

Gold plated

A thin film of gold over brass or copper. It can wear through with everyday wear.

Gold vermeil

Gold over sterling silver, at least 2.5 microns thick. Better than plating, still a coating.

14k gold filledWhat you get

A thick layer of solid 14k gold bonded to a brass core. About 100 times more gold than plating, so it holds its color through daily wear.

Gold layers enlarged so you can see the difference.

Handcrafted With Intention

Every piece of Kate Koel jewelry begins not in a factory, not in bulk, but at a workbench where materials are chosen one by one. Gemstones, iridescent shells, and preserved flowers are carefully placed inside glass-like museum quality resin to create depth, light, and movement. No two pieces are ever identical. That is the point. This is handmade jewelry designed for people who want something personal, expressive, and impossible to mass produce.
