Sterling silver can tarnish over time, especially when exposed to salt air, chlorine, sulfur, humidity, and certain chemicals. However, all our sterling silver pieces are rhodium-plated, which significantly reduces tarnishing and helps maintain their shine. Proper care and regular use can also minimize tarnish.

Yes, we use natural gemstones in our designs. Each stone is hand-selected for its quality, beauty, and durability. We also offer lab-created stones as a more sustainable alternative for select pieces.

Gold vermeil (pronounced “ver-may”) is a high-quality gold jewelry made with a base of 925 sterling silver. To be classified as gold vermeil, the gold layer must be at least 2.5 microns thick and of at least 10K gold. At Island by Koa Nani, we use a thicker plating of 14K gold to ensure a longer-lasting finish and superior quality. Gold vermeil offers a luxurious look similar to solid gold but at a more accessible price.

We recommend storing your jewelry in a dry place, away from direct sunlight. Clean it regularly with a soft cloth, and avoid exposure to chemicals, such as lotions and perfumes. Detailed care instructions can be found on each product page.

• Sterling Silver: Store in a dry, cool place, ideally in a tarnish-proof cloth or pouch (like the one included with your order). To clean, use a silver jewelry cleaner and a soft cloth, avoiding harsh chemicals like bleach.
• 14k Gold Jewelry: Clean with a mild soap solution, then pat dry with a soft cloth. Avoid exposing gold to strong chemicals, lotions, and cosmetics, as these may damage the finish.
• Gold Vermeil: Avoid too much exposure to water, lotions, perfumes, or chemicals, as these can wear down the gold layer. Clean gently using a soft cloth to avoid scratching the surface. Do not use abrasive materials or polishing cloths meant for other metals.
• Gemstones: Avoid extreme temperatures, sudden impacts, and contact with household chemicals to keep your gemstones sparkling.

To keep your jewelry in pristine condition:

• Store each piece separately to avoid scratches.
• Use the tarnish-proof pouch or fabric-lined jewelry box provided with your order.
• In humid climates, consider placing a small packet of desiccant crystals in your storage area to absorb excess moisture.
• Avoid direct contact with rubber bands, as the sulfur in them can tarnish sterling silver.

We recommend removing all jewelry before swimming, bathing, or using a hot tub. Chlorine and saltwater can cause discoloration and damage to metals and gemstones. Additionally, avoid wearing jewelry while applying lotions, perfumes, or hair products, as these can negatively affect the longevity of your jewelry.
