For an engagement ring, Spessartine 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 Spessartine apart?
There are several visual cues: both appear various, but often in different saturations; Demantoid (RI 1.88-1.89) shows more brilliance than Spessartine (RI 1.789-1.82). A gemologist can confirm identification using refractive index testing.
Are Demantoid and Spessartine the same mineral?
Yes, both Demantoid and Spessartine belong to the unknown group mineral group. Despite being related, they differ in color, value, and sometimes durability.
