We send an order confirmation by email for every order. If you can’t find yours, check your spam or promotions folder first. If it isn’t there, email [email protected] with the name you used at checkout, and we’ll resend it.

“On demand” or “pre-order” means the piece isn’t immediately in stock. It is being produced or reserved for you, and the estimated shipping timeframe is shown when you order.

Our precious-metal jewelry is produced and certified in Portugal in line with Portuguese and European requirements on restricted substances, including nickel.

Our pieces are made from certified precious metals under Portuguese and EU regulations. Individual sensitivities can still vary. If you have a history of severe allergic reactions, speak to a dermatologist.

Certified precious-metal jewelry has a legally defined composition and is subject to official hallmarking and verification. CINCO’s precious-metal pieces are produced in Portugal within this regulated framework.

Put your jewelry on last, after applying perfume, skincare and makeup. Take it off before showering, swimming, exercising or sleeping. After wearing it, wipe each piece gently and store it in its CINCO pouch in a cool, dry place, away from humidity and direct sunlight.

For 925 sterling silver, use a soft, lint-free cloth regularly. For a deeper clean, use mild soap, warm water and a very soft brush, then rinse and dry the piece completely.

For gold-plated pieces, use only a soft, dry cloth. Avoid polishing cloths, abrasive products, detergents and prolonged contact with water, as these can strip the plating.

No. Gold plating is a finish that wears naturally over time. How it wears depends on factors such as skin chemistry, perspiration, water, perfume, cosmetics and heat; this is normal wear, not a defect.

Many pieces can be re-plated through our Refresh & Reborn service. Email [email protected] with photos, and we’ll send you an estimate.

The materials used depend on the piece. CINCO primarily uses 925 sterling silver, 18ct gold-plated 925 sterling silver and solid gold. The exact composition is listed on each product page.

Yes. Our precious-metal jewelry is officially hallmarked and certified by the INCM Assay Office, as required in Portugal. It is designed and handmade in Portugal by Portuguese jewelers, under strict quality control.

CINCO jewelry is covered for manufacturing defects for 3 years from the date of delivery. Your invoice and order number serve as proof of purchase; there is no separate warranty card.

The warranty does not cover normal wear, accidental damage, loss, improper use or storage, or work carried out by another jeweler.

You can return your order within 14 days of receiving it. Pieces must be unworn and in their original condition and packaging. This includes any gifts, which are considered part of the product. Trying a piece on is fine, but signs of wear or alteration are not.

Custom and engraved pieces are made for you, so they cannot be returned or exchanged.

To start a return or exchange, use our Returns Portal and enter your order details. You’ll receive the instructions and return documents needed to complete the process.
