FAQs

What Metals Do You Work With?

We work with the following metals:

• Aluminum
• Sterling Silver
• 14kt Gold-Fill
• 14kt Rose Gold-Fill
• Copper
• Brass

Will My Jewelry Tarnish?

• Aluminum will not tarnish and is hypoallergenic.
• Sterling Silver, Copper, and Brass may tarnish over time, especially depending on your skin's acidity. Tarnishing can cause slight skin discoloration, but this is harmless and can be easily washed off.
• Gold-filled and Rose Gold-filled pieces are less likely to tarnish, as pure gold doesn’t tarnish. With proper care, these pieces should stay tarnish-free.

We include a polishing pad with every order to help restore the luster of your jewelry.

Gift Wrapping and Packaging

Every piece of jewelry comes in a small black kraft box. A receipt or invoice is not included by default, but if you'd prefer to receive it, just let us know in the note box at checkout.

What’s the Difference Between Stamping and Engraving?

• Engraving is done using a machine to create an impression in the metal. We design, render, and engrave pieces directly in our studio.
• Hand stamping is done by hammering each letter, character, or symbol one at a time with steel tools. This creates slight variations in spacing and alignment, giving each piece its own unique charm and character.

All items in our shop are handcrafted by us!
