Should I choose Tanzanite or Zircon for an engagement ring?
For an engagement ring, Zircon is the stronger choice with a durability rating of 8/10. At 7.5 Mohs hardness, it can withstand daily wear well. Tanzanite (6.5-7.0 Mohs) is softer and more prone to scratching with everyday use, making it better suited for occasional-wear jewelry.
How can I tell Tanzanite and Zircon apart?
There are several visual cues: both appear various, but often in different saturations; Zircon (RI 1.81-2.024) shows more brilliance than Tanzanite (RI 1.685-1.707); they have different crystal systems — Tanzanite is Orthorhombic and Zircon is Tetragonal. A gemologist can confirm identification using refractive index testing.
Can I use Tanzanite instead of Zircon as a birthstone?
Yes, both Tanzanite and Zircon are recognized birthstones for December. Tanzanite is the modern December birthstone and Zircon is the traditional December birthstone, so either is an appropriate choice for that month.
