At Opal & Onyx, we specialise in rare and exclusive pre‑loved luxury pieces. Due to the one‑of‑a‑kind nature of our inventory, all sales are final. We do not accept returns or offer refunds.

Each item is expertly authenticated and described with detailed imagery and condition notes. Our Certificate of Authenticity and security tag accompany every piece. Because all items are pre‑owned, we cannot honour brand‑specific warranties after purchase. We encourage you to review all details and contact our Concierge Team for any pre‑purchase inquiries. Thank you for choosing Opal & Onyx — where timeless treasures find new owners.

Absolutely. Every item listed undergoes a meticulous authentication process by brand‑specialist experts trained in stamping, stitching, hardware, materials, date‑codes, serial numbers and overall craftsmanship. We stand behind our authenticators and offer a lifetime guarantee: should any item prove non‑authentic, you are eligible for our 100 % money‑back assurance.

We maintain rigorous standards when accepting items. Each piece is inspected and any notable flaws are clearly described in the listing’s Condition Rating section. Most items are previously owned and therefore may show gentle signs of use. Please review all high‑resolution images and description details — especially size, measurements and condition — before purchasing.

We accept: Visa, MasterCard, American Express, PayPal, Apple Pay, and Opal & Onyx Gift Cards.

Items purchased with a gift card become non‑refundable. Please keep your gift card until you are certain of your purchase. Gift cards cannot be used for Reserve orders unless applied manually via phone. We are not responsible for lost or stolen gift cards.

Sales tax is calculated at checkout based on your shipping address (zip or postal code). If your shipping address is changed prior to payment, the applicable tax rate may update accordingly. Tax must be paid in full for shipment to proceed.

We provide detailed, high‑resolution images and a stated Condition Rating for each listing. If you require further clarification — for example specific close‑ups or measurements — our customer service team is happy to assist you before purchase.

No. All items are pre‑owned and we are not affiliated with the original brand manufacturers. We inspect every item, but cannot provide future warranties for wear or damage that occurs post‑purchase.

Orders are shipped in discreet, plain cardboard packaging to protect the luxury nature of the items. Inside you’ll find the signature un‑boxing experience: black & pink confetti, a branded nail file, protective tissue, all inside our decorative packaging.

Gift purchases can only be returned or addressed by the original purchaser’s account. Refunds can only be issued to the original payment method or an Opal & Onyx Store Credit Gift Card issued via email.

Resale pricing may exceed original retail for several reasons:

• Vintage & Rarity – Limited edition or discontinued pieces command a premium.

• Sold Out – Items no longer available at retail often increase in value.

• Original Price Tags – Some older items carry outdated price tags; current market demand may elevate value beyond that tag.

• Supply & Demand – High demand or rapid sell‑through can drive up pricing in the resale market.

Orders generally ship within 3‑5 business days. Expedited orders placed before 11:00 AM (PT) may ship same‑day; after 11:00 AM (PT), they ship next business day. We operate Monday–Friday, 7 AM–5 PM (PT). Discrepancies in billing or shipping details may delay dispatch. You can view full shipping terms in our Shipping Policy.

Yes. At Opal & Onyx, protecting your personal information is a top priority. We implement up‑to‑date administrative, technical and physical safeguards, and our team is trained regularly in security best practices.

The estimated delivery date is an approximate timeframe based on order processing and transit time. Although we aim to meet this date, times may vary due to customs, courier delays or other external factors.
