Tanzanite, a mesmerizing blue-violet gemstone, has captured the hearts of gem enthusiasts and collectors since its discovery in the late 1960s. This unique gem, found only in the Merelani Hills of Tanzania, is renowned for its exceptional beauty and rarity. Among the various cuts that enhance its allure, the trillion cut stands out as a particularly striking choice. In this article, we will explore everything you need to know about trillion cut tanzanite, from its history and characteristics to its value and care.
The Discovery of Tanzanite
Origins and Rarity
Tanzanite is a relatively recent discovery in the gem world. It was first found in 1967 by Masai tribesman Ali Juuyawatu in the foothills of Mount Kilimanjaro. The gemstone was initially mistaken for sapphire due to its vivid blue hue. However, subsequent analysis revealed that it was a previously unknown variety of the mineral zoisite. Named after its country of origin, tanzanite remains incredibly rare, with its deposits limited to a small area in Tanzania.
Geological Formation
Tanzanite is formed under specific geological conditions, requiring the presence of vanadium, which gives the stone its unique blue-violet color. The gemstone forms in metamorphic rocks through a process that involves intense heat and pressure over millions of years. This specific and rare combination of factors contributes to tanzanite’s exclusivity and high value.
Understanding the Trillion Cut
What is a Trillion Cut?
The trillion cut, also known as the trilliant cut, is a triangular shape with 31 to 43 facets. It was first developed in the 1960s by the Henry Meyer Diamond Company. The cut is designed to maximize the brilliance and fire of a gemstone, making it a popular choice for various types of jewels. For tanzanite, the trillion cut enhances the stone’s natural pleochroism, which is the ability to show different colors when viewed from different angles.
Characteristics of the Trillion Cut
Shape and Symmetry: The trillion cut features a triangular shape with equal sides, creating a balanced and symmetrical appearance. The cut’s precision allows light to enter the stone and reflect back brilliantly.
Faceting: Typically, a trillion cut stone will have 31 to 43 facets. These facets are strategically placed to maximize light reflection and refraction, enhancing the gemstone’s sparkle.
Versatility: The trillion cut can be applied to both large and small gemstones, making it a versatile option for various jewelry pieces such as rings, earrings, and pendants.
Advantages of the Trillion Cut for Tanzanite
The trillion cut is particularly advantageous for tanzanite due to the gemstone’s unique optical properties. Tanzanite exhibits pleochroism, displaying different colors (usually blue, violet, and burgundy) when viewed from different angles. The faceting of the trillion cut enhances this effect, creating a mesmerizing play of colors that adds to the stone’s allure.
Evaluating Trillion Cut Tanzanite
Color
Color is one of the most critical factors in evaluating tanzanite. The most prized tanzanites exhibit a deep, vivid blue with violet undertones. When cut into a trillion shape, the stone’s pleochroism can make the colors appear more dynamic, shifting between blue and violet as the gemstone moves. High-quality trillion cut tanzanite will display intense, well-saturated colors without any noticeable color zoning.
Clarity
Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. While some inclusions are acceptable in tanzanite, especially if they are not visible to the naked eye, the best trillion cut stones will be eye-clean, meaning no inclusions are visible without magnification. The trillion cut, with its multiple facets, can sometimes help mask minor inclusions, making the stone appear clearer.
Cut Quality
The quality of the cut is crucial for any gemstone, but it is particularly important for trillion cut tanzanite. A well-executed trillion cut will ensure that the stone’s facets are symmetrical and properly aligned, allowing for maximum light return and brilliance. Poorly cut stones may appear dull or lifeless, lacking the sparkle that makes tanzanite so captivating.
Carat Weight
Like all gemstones, tanzanite is measured in carats. While larger stones are generally more valuable, the trillion cut can make smaller stones appear larger due to its broad, shallow shape. This makes trillion cut tanzanite an excellent choice for those looking to maximize the visual impact of their jewelry without the cost associated with higher carat weights.
Trillion Cut Tanzanite in Jewelry
Rings
Trillion cut tanzanite is a popular choice for rings, especially engagement rings. The triangular shape of the stone creates a unique and modern look that stands out from traditional round or oval cuts. Additionally, the trillion cut can be set with side stones or as a solitaire, offering versatility in design.
Earrings
Earrings featuring trillion cut tanzanite are both elegant and eye-catching. The cut’s brilliance and color-shifting properties make it an excellent choice for studs or dangle earrings. Paired with diamonds or other complementary gemstones, trillion cut tanzanite earrings can be a stunning addition to any jewelry collection.
Pendants
Trillion cut tanzanite pendants are a sophisticated choice for those looking to showcase the gemstone’s beauty. The triangular shape draws attention to the stone’s vibrant colors, making it a focal point in any necklace design. Whether set in gold or platinum, trillion cut tanzanite pendants are a timeless and elegant option.

Caring for Trillion Cut Tanzanite
Cleaning
Tanzanite is relatively soft compared to other gemstones, ranking 6 to 7 on the Mohs scale of hardness. This means it requires gentle cleaning to avoid scratching or damaging the stone. To clean trillion cut tanzanite, use lukewarm water, mild dish soap, and a soft brush. Avoid using ultrasonic cleaners or steam cleaners, as the high temperatures and vibrations can damage the gemstone.
Storage
Proper storage is essential to maintain the beauty of trillion cut tanzanite. Store the gemstone separately from harder stones like diamonds and sapphires to prevent scratching. Use a soft pouch or a lined jewelry box to protect the stone from dust and impact.
Regular Maintenance
Regular maintenance can help keep your trillion cut tanzanite looking its best. Inspect the setting periodically to ensure the stone is secure and not at risk of falling out. Additionally, have the gemstone professionally cleaned and inspected by a jeweler at least once a year.
The Value of Trillion Cut Tanzanite
Market Demand
The value of trillion cut tanzanite is influenced by market demand, which has been consistently high since the gemstone’s discovery. Tanzanite’s limited supply and unique characteristics make it a sought-after gem, particularly in the trillion cut, which showcases the stone’s color and brilliance.
Investment Potential
Due to its rarity and beauty, trillion cut tanzanite holds significant investment potential. High-quality stones can appreciate over time, especially as tanzanite mines become depleted. Collectors and investors often seek out trillion cut tanzanite for its distinctive appearance and the potential for value growth.
Certification and Authenticity
When purchasing trillion cut tanzanite, it is essential to ensure the stone’s authenticity and quality. Reputable sellers will provide certification from recognized gemological laboratories, such as the Gemological Institute of America (GIA) or the American Gemological Laboratories (AGL).
