Frequently Asked Questions
Care & Maintenance
How should I clean my jewelry at home?
Line a small bowl with aluminum foil, add two tablespoons of baking soda, and boiling water.
Let your jewelry soak for 5–10 minutes, then gently polish with a soft cloth.
​
Can I shower or swim with your jewelry?
We recommend avoiding exposure to water, chlorine, and harsh chemicals to maintain the integrity and shine of your jewelry.

Will silver or gold jewelry tarnish over time?
Sterling silver may naturally oxidize; gold (especially 14K/18K) is more resistant.
Regular gentle cleaning helps preserve its shine.

How can I store my jewelry to prevent damage?
Keep your pieces in a soft pouch or separate compartment to avoid scratching or tangling.
