How to Spot a High-Quality Tanzanite
Tanzanite is one of the most mesmerizing gemstones, known for its unique ability to shift colors from deep blue to violet. But with its rarity comes the challenge of distinguishing a high-quality tanzanite from lesser stones. Whether you're purchasing a tanzanite ring, a pendant, or earrings, understanding the key quality factors is essential to making a wise investment.
When evaluating tanzanite, experts consider four main aspects: color, clarity, cut, and carat weight. These factors determine both the beauty and the value of the stone.
Color: The Most Important Factor
The most desirable tanzanites exhibit a deep, rich blue or a violetish-blue hue. The intensity of the color is critical—the deeper the saturation, the higher the value. Larger stones (typically over 5 carats) often show the richest colors, while smaller tanzanites may appear lighter. Because of tanzanite’s pleochroic nature, meaning it can display different colors depending on the viewing angle, expert cutting is necessary to enhance the most vibrant shades.
Clarity: Eye-Clean is Best
A high-quality tanzanite should be eye-clean, meaning no visible inclusions when viewed with the naked eye. As a Type I gemstone, tanzanite generally has very few internal flaws. However, any visible inclusions can greatly impact its value. When purchasing, ensure the gemstone is free of noticeable blemishes and internal fractures.
Cut: Maximizing Brilliance
The cut of a tanzanite gemstone directly affects its sparkle and color presentation. Due to its pleochroic properties, skilled gem cutters must carefully orient the stone to bring out the most attractive hues. A well-cut tanzanite will have excellent symmetry and proportion, allowing light to reflect beautifully. Poorly cut stones may appear dull or have a window effect, where light passes straight through without reflecting back.
Carat Weight: Bigger is Often Better
While carat weight is not the primary quality factor, it does influence a tanzanite’s overall appeal. Larger stones tend to have richer, more intense colors, making them more valuable. However, it’s important to balance size with quality. A smaller, well-cut, and deeply colored stone can be more valuable than a larger, pale one.
Choosing the Perfect Tanzanite
When shopping for a tanzanite piece, consider how it complements different white gold or rose gold settings. Whether in a tanzanite pendant, bracelet, or statement ring, this gemstone's enchanting hues make it a standout addition to any jewelry collection.
By focusing on color, clarity, cut, and carat weight, you can confidently select a high-quality tanzanite that will remain a cherished piece for years to come. Explore Robinson’s Jewelers’ exclusive tanzanite collection to find your perfect gemstone today.
