Tanzanite is found only in northern Tanzania, and a little homework on dealers, certificates and paperwork helps you bring home a genuine stone at a fair price.
Tanzanite, the violet-blue gemstone found only in the Merelani Hills near Arusha, is one of the most popular souvenirs for visitors to northern Tanzania. Seeing it close to where it comes from is part of the appeal.
Gemstones are also a classic area for overpricing and fakes worldwide. With a few sensible precautions, you can shop with confidence and enjoy the purchase rather than worry about it.
Quick tips
- Buy only from established shops with a permanent address.
- Ask whether the stone has been treated and get the answer in writing.
- Request a certificate and itemized receipt for any valuable purchase.
- Keep purchase documents in your carry-on bag for departure.
- Avoid rough or uncut stones offered informally.
Buy from licensed, established dealers
Stick to reputable jewelers and gem shops with a permanent location, clear pricing and a willingness to answer questions. Avoid buying loose stones from street sellers or anyone who approaches you with a deal that sounds urgent or secret.

Understand what affects value
Color is the biggest factor, with deeper, more saturated violet-blue stones generally commanding higher prices. Clarity, cut and carat weight also matter. Most tanzanite on the market has been heat treated to enhance its color, which is standard practice in the trade, but a trustworthy seller will tell you so.
- Color: depth and saturation of the blue-violet hue
- Clarity: fewer visible inclusions usually means higher value
- Cut: good proportions bring out brilliance
- Carat: larger stones of good color are rarer
Ask for a certificate and proper receipt
For a significant purchase, ask for a certificate or grading report describing the stone, along with a detailed receipt showing the dealer's details, the stone's description, weight and price. Keep all documents with the stone and store copies digitally.
Export paperwork and customs
Rules on exporting gemstones exist, and rough, uncut stones in particular are subject to restrictions. Buying cut stones or finished jewelry from licensed dealers, who can provide the correct documentation, is the simplest route. Keep your receipts and any export paperwork in your hand luggage, as you may be asked for them when leaving Tanzania.
Check your home country's customs allowances too, since you may need to declare valuable purchases on arrival.
Shop without pressure
Take your time, compare a few shops and set a budget before you start. Look at stones in natural daylight as well as shop lighting, since tanzanite can appear different under each. If you feel rushed, walk away.
Pay with a card where possible for larger purchases, and make sure the amount and currency on the slip match what you agreed.
Seeing tanzanite close to its source
The Merelani Hills, where tanzanite is mined, lie between Arusha and Kilimanjaro, and the stone's story is closely tied to this region. Some visitors enjoy learning about how it is mined, cut and graded before deciding whether to buy at all.
Treat any purchase as something you love wearing rather than an investment. Resale values for gemstones are hard to predict, and buying for pleasure keeps expectations realistic. If you are unsure, it is perfectly fine to admire the stones and simply leave with a photo.
Frequently asked questions
Is tanzanite cheaper in Tanzania?
It can be, but not automatically. Prices depend on quality and the seller, so compare shops and focus on reputable dealers rather than assuming any stone is a bargain.
How can I tell if tanzanite is real?
Visual checks alone are unreliable, as glass and synthetic stones can look convincing. Buying from a reputable dealer who provides a certificate and detailed receipt is the best safeguard.
Do I need paperwork to take tanzanite home?
You should keep the receipt and any documentation the dealer provides, as officials may ask to see it when you leave. Check current rules with the dealer, especially for rough stones, which face export restrictions.
