Select jewelry in our collections may be engraved where noted. You may include the message you would like to have engraved at checkout.

Please contact our client care experts to discuss your specific piece. Depending on your piece, Oscar Massin might offer you an adjustment service or simply an exchange of your product, as some of our rings cannot be resized.

Our Maison jewelry experts apply their technical know-how to finely shape the metal of a ring, modify the length of a chain, adapt the post or clip mechanism of an earring.

As this service is always undertaken with respect to the original technical and aesthetic specifications of each creation, please refrain from using outside workshops and contact our client care with any questions.

We believe that fine jewelry is to be worn, celebrated, and shared with the world. Our medium diamond hoop earrings from our Beaded collection are intentionally designed with an angle that prevents the jewelry from touching your cheeks as you move. Experience the collection in AR.

We use only 18K, 100% recycled white and yellow gold, which stands up to moisture and resists tarnish.

Lab-grown diamonds are created using Chemical Vapor Deposition (CVD), a diamond growth process that uses the highest quality Type IIA diamond “seeds” and grows them in specialized greenhouse-like chambers that mirror natural growth conditions. This results in 100% climate-neutral diamonds with full origin traceability— physically, atomically and optically identical to their mined counterparts.

Topping the charts in the traditional 4Cs, our laboratory-created diamonds are also individually certified against The 5th C: Climate Neutrality™. This third-party verification reflects the net zero carbon footprint, and the negation of all legacy and current environmental impacts.

Actions are considered “Climate Neutral” or “CO₂ Neutral” if they do not put a strain on the climate, i.e., if they do not create greenhouse gases.

Climate Neutrality can be achieved if CO₂ emissions are reduced to a minimum and all remaining CO₂ emissions are offset with climate protection measures. If climate-damaging greenhouse gases are completely avoided or if gases that have already been emitted are saved elsewhere, this is referred to as “Climate Neutral.”

At this time, we are unable to offer upcycling or repurposing services.

A Sustainability Rated Diamond is a diamond that has been evaluated against five pillars of sustainability achievement and is found to be in full conformance with the requirements of the SCS-007 Jewelry Sustainability Standard developed by SCS Global Services.

Oscar Massin maintains the highest standards in design, craftsmanship and materials. With proper care, you can preserve the beauty of your Oscar Massin piece and accessories for years to come.

Oscar Massin Maison offers multiple services to ensure your jewelry are optimally maintained and is helping you care for your jewelry, offering a preservation service to safeguard its integrity and condition.

We offer a 2-year warranty on your jewelry for repairs, replacements and maintenance. If you believe that your jewelry has a manufacturing defect, please send it back to us for assessment and we will repair or replace it as necessary. Please note: our warranty excludes lost or stolen jewelry, damages resulting from negligence, natural tarnishing that may occur over time, and jewelry purchased from an unauthorized retailer.

Our jewelry is extremely delicate and meticulously designed; repair requires extensive, nuanced product knowledge and expertise. Should you choose to have your jewelry repaired or altered by a third-party jeweler, it will no longer be covered under our 2-year warranty.

We do not recommend using an outside jeweler to change the product. Our products are incredibly delicate and should be handled by our Maison jewelry experts who know our products and can care for them best. Once you have used an outside jeweler, we can no longer offer warranty on our products.

We accept all major debit and credit cards including Visa, MasterCard, American Express, and Discover, as well as PayPal, Amazon Pay, Apple Pay, and Google Pay. We do not accept cash, personal checks or money orders.

We are here to ensure that your credit card information is safe and secure whenever you place an order from oscarmassin.com, which uses HTTPS protocol to encrypt your personal information and integrates physical, electronic, and administrative procedures to safeguard the confidentiality of your personal information, including Secure Sockets Layer ("SSL") for all financial transactions through our website. As part of our verification process, all orders are also reviewed by our external consultancy.

A common reason for declined credit cards is an incorrect billing address. When you checkout, please be sure that your personal information matches the information on your credit card exactly. If your payment is still declined, we recommend contacting your financial institution. If you are experiencing other issues at checkout, please reach out to client care: hello@oscarmassin.com so that we may assist you.

For optimal security, when an order is submitted an authorization request is sent to the issuing bank or financial institution. The issuing bank verifies your credit card and billing information. If the card information is valid, the bank places an authorization hold on the funds. An authorization is only a hold on the funds for a potential future transfer.

When you place an order at oscarmassin.com, you may see two transactions posted to your account:

1) Authorization which places the funds on hold to accommodate the pending charge;

2) Order charge, once your purchase has shipped and the funds have been received. 

Once your financial institution releases your payment, you will see a single charge on your account. If an order is canceled, the authorization hold will be removed by your financial institution.

Sales tax is applied to your order in accordance with individual U.S. state and local regulations and may be charged without notice. For orders shipped to other states or countries, your state and/or municipal government may require you to declare your purchase and directly pay the corresponding sales tax.

All jewelry on our site is priced in United States dollars (USD). Your bank or credit card issuer may charge a currency conversion fee for your purchases at.oscarmassin.com. We are not responsible for these conversion fees. For additional information about foreign currency conversion, please visit this page:
