Flow Pendant Necklace in Dalmatian Jasper
$88.00

A gold wire wave cradles three dalmatian jasper gemstones in this 14k gold filled chain necklace. I love wearing this necklace to elevate a tee and jeans.

  • Dalmatian jasper gemstones. Each gemstone is one of a kind, so your piece will be unique and may vary slightly from what’s pictured.

  • 14k gold filled wire, chain, and clasp. 14k gold filled gives you the look and lasting quality of solid gold at a more approachable price, with a thick layer of real gold that won’t wear off like plating.

  • Adjustable length from 16"-18". Jump rings sit at 16”, 17”, and 18” along the chain so you can clasp at the length that fits you best. Sits at the base of the neck at 16” and the collarbone at 18”.

  • Front pendant measures about 1” x 3/4”.

  • Handmade. Made by me (👋🏼) in Marin County, California.

Reyes Half Moon Hoop Earrings in Green Moss Agate
$58.00

These gold filled half-moon hoops slip right through your ear and finish with a single green moss agate bead, its soft, earthy swirls catching the light as you move. They’re lightweight enough to forget you’re wearing them, and polished enough that you’ll still get the “where’d you get those?” question. Easy on a Tuesday, just as good on a Saturday night.
