Tanzanite's story is unlike any other gemstone's. Found only in one place on Earth—Tanzania’s Merelani Hills—this striking blue-violet stone has captured the hearts of gem lovers worldwide. Its vibrant colors and limited supply make this December birthstone truly one-of-a-kind.
But before reaching jewelry stores, tanzanite takes an incredible journey from deep within the earth to your favorite pieces. If you have any questions regarding this December birtshtone’s origin and more, this is the best place to get your answers. Let’s dive in to find out!
The Origin
Tanzanite was discovered in 1967, and immediately, its beauty became the talk of the gem world. The vibrant gemstone owes its hues to vanadium, a mineral that enriches its natural colors. Mining tanzanite, however, is no simple task. Found deep in the mountains of Tanzania, the process requires dedication, skill and patience.
The Merelani mines are known for their complex structure, making extraction challenging and labor-intensive. Once mined, tanzanite gemstones undergo sorting based on size, clarity and color. The process prepares them for the next step in their journey.

Transforming Raw Gemstone
Raw tanzanite lacks the sparkle and polish we associate with finished gemstones. That’s where skilled artisans come in. Cutting and polishing tanzanite gemstones require precision to enhance their natural beauty. Expert gem cutters carefully examine each stone, deciding the best angles to reveal tanzanite’s striking color spectrum.
A high-quality cut brings out the gemstone's vivid blue and violet hues, making it shine in any setting. Each stage of polishing and finishing reveals a new layer of brilliance, setting tanzanite apart from other stones in the market.
Tanzanite Grading
Once cut and polished, loose tanzanite gemstones undergo a grading process to determine its quality. Grading involves evaluating factors such as color, clarity and carat weight. The most prized tanzanite is graded as “AAAA” for its exceptional color and clarity.
This level of quality means that tanzanite gemstones are incredibly vibrant, free from major inclusions and have a deep hue. These graded gems are then prepared for sale, ensuring that each piece meets the high standards gem lovers expect.

Designing Jewelry Pieces
After grading, tanzanite makes its way into the hands of jewelry designers. Each designer brings their unique vision, crafting rings, necklaces and earrings that highlight tanzanite’s colors and brilliance.
Whether set in gold, platinum or silver, tanzanite goes well with every setting. Such a jewelry piece brings elegance to any jewelry collection. Tanzanite’s versatility and vibrant hue make it a favorite for both classic and modern designs. And this allows wearers to experience a gemstone with unmatched beauty.
Demand in the Market
Tanzanite’s rarity and beauty have made it a highly sought-after gemstone worldwide. With limited supply and increasing demand, tanzanite has become a valuable asset in the gemstone market.
Retailers and collectors alike treasure it for its exclusivity and investment potential. While the market sees other gems from various locations, tanzanite’s single-source origin in Tanzania adds to its appeal. From local Tanzanian shops to global markets, Tanzanite’s journey reflects the rich history and culture of the region it originates from.
A Gem Fit for the Stars
Celebrities have long adored tanzanite for its captivating color and unique origins. This striking gemstone has found its place among the jewelry favorites of Hollywood stars. A-listers such as Anne Hathaway and Cate Blanchett have been spotted wearing stunning Tanzanite pieces.
After their appearances, the demand for the December birthstone jewelry skyrocketed. For celebrities, tanzanite represents not just luxury but also a unique connection to a precious gem found nowhere else on Earth.
Caring for Your December Birthday Jewelry
These December birthstones deserve special care to maintain their brilliance and beauty. Unlike harder gemstones, tanzanite is relatively delicate, so it’s best to avoid wearing it during activities that could cause scratches.
To clean, use a mild soap solution and a soft brush, gently wiping away dirt and oils. Avoid ultrasonic cleaners or harsh chemicals, which can damage the stone. When not in use, store tanzanite jewelry in a soft pouch or separate jewelry compartment to prevent scratching.
