Prepaid Import Duties & Taxes
Highline Diamond prepays all applicable import duties and taxes. Any applicable sales tax will be shown in your final order total at checkout; no import duties are due upon delivery.
Production Time
Since every HIGHLINE DIAMOND piece is handcrafted specifically for you, please allow 15 business days (excluding weekends and holidays) for production after your order is confirmed. Once your jewelry is ready, you will receive a tracking number immediately.
Eligible standard collection pieces may be returned or exchanged within 30 days of delivery. Refunds to the original payment method are subject to a made-to-order return fee equal to 10% of the amount actually paid for the returned merchandise, capped at US$300 per return. The 10% fee does not apply to exchanges.
Customers are responsible for shipping items to Highline Diamond. For exchanges, we cover shipping of the replacement item back to you, with applicable duties and taxes prepaid. Complimentary delivery does not include shipping items back to Highline Diamond.
For an exchange to a higher-priced item, the balance must be paid before shipment. If the replacement item is lower in price, the difference will be issued as store credit.
Engraved items remain eligible with a US$40 engraving removal and refinishing fee per item. Fully bespoke pieces and items significantly damaged after delivery are not eligible; minor surface scratches alone do not make an item ineligible.
Any IGI grading report supplied with the item must be returned, or a US$100 replacement fee will apply per missing report.

Crafted in your choice of solid 9K, 14K or 18K gold, or platinum—never gold-plated silver or base metal. Every piece is hand-set by our master setters and finished through a multi-stage polish. Before anything leaves our atelier, it passes inspection under 30x magnification — prong security, stone alignment, surface finish.
Video walkthrough: once your piece is complete, we send you a detailed video of your actual ring so you can verify every detail before it ships.
Certificate match: the laser inscription on your diamond is matched to its IGI certificate before tracked DHL/FedEx dispatch.
