While all jewelry experiences natural wear over time, proper care can significantly reduce unnecessary damage and maintain the integrity of your gemstones and precious metals. 

Jewelry can be affected by several factors. Being aware of these can help preserve your pieces:

Physical: Impacts or pressure can crack gemstones or distort metal.
Chemical: Exposure to cosmetics, cleaning agents, or perfumes may corrode metals and dull stones.
Water: Chlorinated or salt water can tarnish metals and weaken gemstone structures.
Heat & Sunlight: High temperatures and UV exposure may cause fading or fractures.
Residue Buildup: Oils, lotions, and makeup can create films that reduce brilliance.
Improper Storage: Stacking pieces together may cause friction and long-term damage.
DIY Repairs: Incorrect techniques can compromise the structure of your jewelry.

Jewelry Cleaning
To maintain the luster and shine of your jewelry, we recommend cleaning your pieces regularly. The following guidelines will help preserve their beauty:

• Gently polish your jewelry with a dry, soft microfiber cloth to maintain its shine and remove surface residue.
• For a deeper clean, briefly soak the piece in warm water with mild soap.
• Use a soft brush to gently clean around settings, then rinse and dry thoroughly with a soft cloth.
• Avoid ultrasonic cleaners, steam cleaners, abrasive products, or DIY repair techniques, as they can cause irreversible damage, especially to delicate stones.

Inspired by nature

Mar de Luna is a sustainable fine jewelry house guided by the principles of people, planet, and beauty. Rooted in Colombia, we celebrate the timeless allure of our emeralds — true treasures of the earth — while empowering local communities and crafting pieces that transcend time and trend.

"TODO COLOMBIANO
DEBERIA TENER UNA
ESMERALDITA".

Where do our emeralds come from,
and why are they so special?

Meet Dinael, our chief miner. Dinael is one of the 89 registered barequeros in Colombia. He lives and works in a small village of roughly 500 inhabitants, surrounded by millenary mountains, sacred lakes, and ancient Indigenous territories. To him, finding an emerald — or rather, the emerald finding you — is a sacred act that requires respect, faith, and intuition. He honors the mountain, and in return, the mountain provides.

Barequeros are artisanal miners authorized by the Colombian government to extract emeralds in traditional, small-scale ways that preserve the environment and cultural heritage of the region. At Mar de Luna, we partner not only with certified mines but go a step further — working with those who ensure their miners, like Dinael, have access to safe working conditions, health insurance, and a stable income even during periods with no emerald production, all while complying fully with Colombia’s environmental regulations.

This doesn’t mean our pieces come at a premium; it means they are crafted with integrity — unique, limited in scale, and deeply rooted in the well-being of the communities behind them. The miners. The true heroes of our story.
