Why Buy Loose Tanzanite Gemstones For Custom Jewelry from GemSelect?

What Makes Tanzanite So Special?

Tanzanite, a variety of zoisite, was discovered in 1967 and named after its sole source: Tanzania. Unlike other gems, it exhibits three colors (trichroism) - blue, purple, and hints of red - when viewed from various angles, creating dynamic depth in your custom jewelry. As the December birthstone, it symbolizes transformation and spirituality, adding personal meaning to heirloom-quality pieces.

  • Rarity: Found only in one 4-square-mile area, supplies are depleting, enhancing its investment value.
  • Color: Vibrant violet-blue tones, with AAA and AAAA grades offering the richest saturation.
  • Clarity & Cut: High clarity (eye-clean) and precision cuts maximize brilliance.
  • Hardness: 6.5-7 on the Mohs scale - durable for everyday wear with proper care, though softer than sapphire or ruby.

Why Choose Loose Tanzanite for Custom Jewelry?

Opting for loose Tanzanite gemstones for custom jewelry empowers you to craft pieces that reflect your unique style. Whether you're a designer envisioning a statement necklace or an individual seeking a custom engagement ring, these versatile stones adapt to any setting - from minimalist gold bands to elaborate platinum halos.

Benefits include:

  • Flexibility: Select exact sizes (from 0.5ct to over 20ct), shapes, and qualities to fit your design.
  • Affordability: Prices start at $30 and reach $5,000+, far more accessible than comparable sapphires while offering superior size options.
  • Ethical Sourcing: Our gems are certified natural, heat-treated for optimal color (a standard industry practice), and mined sustainably.
  • Investment Potential: As mining areas dwindle, Tanzanite's value appreciates, making your custom piece both beautiful and savvy.

Imagine a pear-shaped Tanzanite pendant that catches the light with electric blue flashes or trillion-cut earrings that sparkle with violet undertones - all customized to perfection.

Care Tips for Your Custom Tanzanite Jewelry

To keep your loose Tanzanite gemstones shining in custom settings:

  • Clean with mild soap and warm water; avoid ultrasonics or chemicals.
  • Store separately to prevent scratches.
  • Remove during heavy activities - its softness means it deserves gentle handling.

No problems. I had a minor address issue in the past and someone got back to me very quickly and we resolved the issue satisfactorily. I appreciated the quick, concerned response. So important when buyer/seller are so far apart in distance. Thank you Gem Select. Keep up the good work!
