Copper remembers every hammer blow

Every piece passes through fire.

Heat paints copper in blue, violet, rose and gold. Where it has aged into turquoise, your light polishes the stone and wakes its golden veins. Strike the copper and it dents. Strike the turquoise and it cracks into pieces, mended along its veins with gold.

The maker

Meet Nigora

Every piece on this site is made by one person, by hand, in a home studio in Penn Valley, California.

Her designs move between modern, boho and rustic. They grow out of her love of nature and her heritage, out of color, beads and gemstones, and out of texture hammered straight into the metal. She works mostly in copper, and in sterling silver, brass and bronze when a piece asks for it.

Her husband is her biggest supporter and her toughest critic. Sierra, her German Shepherd, keeps her company at the bench.

  1. It began with seed beads

    Tiny glass beads, strung one at a time. Before long, beads were not enough.

  2. Then came metal

    She taught herself to cut and form copper, to work with hammer, fire and solder, and to set stones.

  3. 2016: Sierra Hill Studio opens on Etsy

    Her first pieces went out to buyers across the country, each one gift wrapped by hand.

  4. Today

    379 pieces have found their homes, rated 4.9 out of 5 by 150 buyers. Still one woman, one bench, one piece at a time.

At the bench

From copper sheet to finished piece

Watch a pendant take shape, or tap a step. And as you scroll, the copper behind this page turns turquoise, the way copper ages in nature.

  1. Cut

    Every piece starts as a flat sheet of copper, sterling silver or brass, cut and shaped by hand.

  2. Forge

    Hundreds of hammer blows give each piece its form and the texture you can feel.

  3. Fire and set

    Joins are soldered with a torch, and stones are set one at a time.

  4. Finish

    Copper is aged, polished and sealed with Renaissance Wax, so it keeps its glow.

Giving it

A gift that arrives ready to give

Every order ships in a cotton filled gift box with a small polishing pad, so it is ready to hand over the moment it arrives. Many buyers write that the piece was a gift, and that it was received with delight.

Copper is the traditional gift for a 7th wedding anniversary. A hand forged copper piece is a way to say it with something that will last.

Questions buyers ask

How fast will my order ship?

Orders ship within 1 to 3 business days by USPS First Class, with tracking. Priority or Express shipping is available. Just ask before you order.

Will copper turn my skin green?

It can. Copper reacts with sweat, lotion, water and other products on the skin, and that reaction can leave a faint green mark. According to a dermatologist at Nebraska Medicine, the green residue is not harmful and washes off with soap and water. Every metal piece from the studio is sealed with Renaissance Wax, which slows the reaction. Keeping the piece dry and wiping it after you wear it helps too. Some people also brush a thin coat of clear nail polish on the inside of a ring or bracelet and reapply it now and then.

I have a metal allergy. Can I wear these pieces?

Nickel is the most common culprit. The American Academy of Dermatology notes that nickel allergy often starts with jewelry, especially earrings and earring backs, and suggests nickel free or hypoallergenic metals such as sterling silver. Check the materials on the piece page, and if you have a known allergy, write to Nigora before ordering. She can tell you exactly what touches the skin and whether a piece can be made with a different metal.

How do I clean my piece?

Rub it gently with the polishing pad that came with it, or any jewelry polishing cloth. Mild soap and water will not hurt the finish, just dry it right away. Skip jewelry dips, harsh cleaners and ultrasonic cleaners. Many pieces have an aged, darkened finish on purpose, and strong cleaners strip it. Full care guide.

Can I return a piece?

Yes. Contact Nigora within 3 days of delivery and ship the piece back within 10 days, unworn and insured. The refund covers the item, not shipping. Please message her before sending anything back. Custom pieces cannot be returned.

Do you make custom pieces?

Yes, gladly. Tell Nigora your idea: a stone you love, a metal, a color, a length, a date. Custom work usually takes 1 to 3 weeks, and a rush is possible for a fee. She sends a photo for your approval, then creates a reserved listing for you on Etsy. Custom pieces cannot be returned or cancelled once work begins. How custom pieces work.

How do I find my bracelet size?

Measure your wrist snugly with a soft tape measure, or wrap a strip of paper around it and measure the paper. Then add 3/4 to 1 inch for a comfortable fit.

Do you ship outside the United States?

Not right now. Orders ship within the United States only.
