💫 Cinnamon lore and care
Hessonite is not a separate mineral species but a warm-coloured variety of Grossular Garnet. It may resemble orange Spessartine, Citrine, Topaz or Zircon, but Hessonite is typically distinguished by its Grossular properties, singly refractive behaviour and characteristic treacle-like interior. The historic names “hyacinth” and “jacinth” are ambiguous and have also been used for Zircon and other reddish-orange gems.
Hessonite measures approximately 6.5–7.5 on the Mohs scale and has no cleavage, although it remains brittle and may chip under a sharp blow. Clean it with lukewarm water, mild soap and a soft brush, then dry thoroughly. Avoid steam, sudden heat, abrasive cleaners and ultrasonic cleaning when fractures, fillings, inclusions or delicate settings are present.
