Tomales Pendant Necklace in Crazy Lace Agate

$98.00

This simple geometric pendant features a natural crazy lace agate gemstone held by a hand-formed wire arc, and strung on a 14k gold filled cable chain. This necklace can be dressed up or down. I think it brings an elevated earthy feel to a relaxed linen shirt.

Crazy lace agate gemstone. 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 18"-20". Jump rings sit at 18”, 19”, and 20” along the chain so you can clasp at the length that fits you best. Sits at the collarbone at 18” and the center of the chest at 20”.
The pendant measures about 1/2” wide x 3/4” long.

Reyes Half Moon Hoop Earrings in Green Moss Agate

$58.00

These 14k 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.

Tidepool Beaded Chain Link Necklace in Green Moss Agate

$118.00

This beaded necklace features green moss agate rondelles grouped along a dainty 14k gold filled chain. The beads sit only on the front, so the necklace feels lightweight and makes a statement without looking chunky. I wore it with a simple black silk wrap dress to a wine country wedding and felt pulled together and comfortable all night.

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.
