How Do I Choose a Good Tanzanite? A Guide to the Gemstone's Allure

Tanzanite, with its captivating blend of blue and violet hues, has captivated jewelry enthusiasts for decades. This relatively rare gemstone boasts a mesmerizing play of color, making it a truly unique choice for rings, necklaces, and earrings. But with so many options available, how do you ensure you're selecting a good tanzanite?

This comprehensive guide, brought to you by Blue Star Gemstones, will equip you with the knowledge you need to confidently choose a stunning tanzanite piece. We'll delve into the key factors that influence its quality, along with valuable tips to navigate the world of tanzanite selection.

Understanding the 4Cs of Tanzanite

Just like diamonds, tanzanite's value hinges on four crucial aspects: Color, Clarity, Cut, and Carat weight. Mastering these concepts will empower you to make informed decisions when purchasing a tanzanite gemstone.

• Color: The crown jewel of tanzanite is undoubtedly its color. The most desirable stones exhibit a vibrant, saturated blue with flashes of violet and red pleochroism. This means the gem displays different colors depending on the viewing angle. Deep, violetish blues command the highest prices, while lighter lilacs or greenish hues fall on the lower end of the spectrum.
• Clarity: Like all gemstones, tanzanite may have inclusions, which are internal flaws or imperfections. While some inclusions are barely noticeable to the naked eye, heavily included stones will have a lower value. Look for tanzanite with minimal inclusions that don't detract from the overall brilliance and beauty.
• Cut: A well-cut tanzanite maximizes its brilliance and fire (play of light). Skilled cutters strive to achieve optimal proportions and symmetry, ensuring light interacts effectively within the stone. Ideal cuts for tanzanite include oval, cushion, and brilliant cuts.
• Carat Weight: This refers to the weight of the gemstone, with one carat equaling 0.2 grams. Naturally, larger tanzanites are rarer and more expensive. However, don't solely focus on size. A smaller, well-cut stone with exceptional color and clarity can be more valuable than a larger, lower-quality tanzanite.

Beyond the 4Cs: Additional Considerations

While the 4Cs form the foundation of tanzanite selection, there are other factors to consider:

• Heat Treatment: Tanzanite is almost always heat-treated to enhance its color and improve clarity. This is an industry-standard practice and doesn't diminish the stone's value. However, some sellers may offer untreated tanzanite at a premium. Be sure to understand the treatment process and ensure the stone comes with a reputable lab report.
• Origin: Tanzanite is mined almost exclusively in the Merelani Hills of Tanzania. While other locations like Kenya or Kashmir may offer similar-looking stones, true tanzanite originates from this specific region.
• Certification: Reputable gem labs like GIA (Gemological Institute of America) or AIGS (American Gem Society) issue reports that detail the stone's characteristics and authenticity. This independent verification provides peace of mind knowing you're purchasing a genuine tanzanite.

Tips for Choosing a Good Tanzanite:

• Set a Budget: Determine your spending limit before embarking on your tanzanite search. This will help you narrow down options and prioritize the most important qualities within your budget.
• Do Your Research: Familiarize yourself with the 4Cs and different tanzanite cuts. Explore online resources and consult with reputable jewelers to gain a solid understanding.
• Shop from Reputable Sources: Choose established jewelers who offer ethically sourced gemstones and prioritize transparency.
• Ask Questions: Don't hesitate to inquire about the tanzanite's origin, treatment, and any accompanying reports. A knowledgeable jeweler should be happy to address your queries.
• Consider Your Preferences: While color and clarity are crucial, prioritize what resonates with you. Do you prefer a more vibrant blue or a subtler violet hue?

Bringing Tanzanite Home: Setting and Care

Once you've chosen your perfect tanzanite, consider the setting to complement its beauty. Platinum or white gold create a classic and elegant look, while yellow gold offers a warmer touch. Discuss setting options with your jeweler to ensure a secure and visually appealing design.

Tanzanite requires proper care to maintain its brilliance. Use a soft brush and lukewarm soapy water for cleaning. Avoid harsh chemicals, ultrasonic cleaners, and sudden temperature changes. Store your tanzanite jewelry in a soft pouch or fabric-lined jewelry box.
