This simply means that you do not pay any sales tax on the items you purchase which significantly reduces the prices. That is why when you visit St. Maarten it is best to purchase expensive items like gold, diamonds, or luxury watches because you are going to get the best possible price and save lots of money.

In 2026, St. Maarten remains a premier destination for diamond shopping because it is a duty-free and tax-free port. This status allows reputable, family-owned jewelers in Philipsburg to offer high-quality stones at prices that can be 20% to 50% lower than retail prices in the United States or Europe. However, the "value" depends entirely on your knowledge and preparation. To ensure a worthy investment, you should only shop at established stores that provide GIA or IGI certifications and a clear return policy. Experts in 2026 recommend doing your research on the "4Cs" (Cut, Color, Clarity, and Carat) before arrival so you can accurately compare prices. While there are significant bargains to be found on rare stones and custom settings, the lack of local sales tax is the primary driver of savings for savvy tourists visiting this Caribbean jewelry hub.
