Import Tax

One Flat Rate Of 15%. No Surprises.

These days, it seems like tariffs are changing every week, which can turn international shopping from an exciting experience into a nightmare. At Tanzanite Direct, we want you to enjoy our beautiful gemstones and jewelry without wondering if you're about to get hit with a huge import tax bill—so we're taking care of the unexpected for you.

No matter where you are in the world, we apply a flat 15% fee at checkout. That's it.

Any other unexpected taxes go on our tab. That's right: if the customs authorities in your country charge you anything on top of that 15%, we will cover the difference.

One small exception:

In some countries and parts of the US, you may be charged a small handling or transaction fee. Unfortunately, we are unable to administer these from our end at this time. Your delivery service will inform you of any such charges, which usually will not exceed USD 50.

TANZANITE WEIGHT & MEASUREMENT

Measurements show the tanzanite’s minimum diameter and depth, measured in millimeters. The measurements are noted as length x width x depth
The “face-up” length and width measurements are the best way to judge a colored stone's actual size—as opposed to carat weight, which can change depending on the variations in each stone's proportions
