Frequently Asked Questions
Which is harder, Demantoid or Tsavorite?
Tsavorite is harder at 7.0-7.5 on the Mohs scale, compared to Demantoid at 6.5. This makes Tsavorite more resistant to scratching. Tsavorite is suitable for daily wear, while demantoid requires more careful handling and is not ideal for daily wear.
Is Demantoid more expensive than Tsavorite?
Demantoid and Tsavorite are in a similar price range, both classified as moderately priced ($50-500/ct). Demantoid typically ranges moderately priced ($50-500/ct), while Tsavorite ranges moderately priced ($50-500/ct).
Should I choose Demantoid or Tsavorite for an engagement ring?
For an engagement ring, Tsavorite is the stronger choice with a durability rating of 7/10. At 7.0-7.5 Mohs hardness, it can withstand daily wear well. Demantoid (6.5 Mohs) is softer and more prone to scratching with everyday use, making it better suited for occasional-wear jewelry.
How can I tell Demantoid and Tsavorite apart?
There are several visual cues: both appear various, but often in different saturations; Demantoid (RI 1.88-1.89) shows more brilliance than Tsavorite (RI 1.735-1.744). A gemologist can confirm identification using refractive index testing.
Are Demantoid and Tsavorite the same mineral?
Yes, both Demantoid and Tsavorite belong to the unknown group mineral group. Despite being related, they differ in color, value, and sometimes durability.
