Spinel Gemstone – Colors, Origin, Properties, and Value

Spinel is one of the most coveted untreated colored gemstones in the world, boasting exceptional brilliance, natural colors, and an enormous variety of rare variants. 
Particularly prized are red Mogok spinels from Myanmar, vibrant Mahenge spinels from Tanzania, and rare gray, violet, and lavender-colored spinels with a unique visual identity. 
The color palette ranges from intense red to pink, violet, blue, and gray, all the way to rare black or colorless varieties. Thanks to its natural beauty, high transparency, and often untreated colors, spinel is now one of the most interesting gemstones for collectors, jewelry enthusiasts, and connoisseurs.
For a long time, spinel was underestimated due to its similarity to ruby and sapphire. Today, however, it is valued for its individuality, its exceptional purity, and its impressive diversity.

What is a Spinel?

  • Strong natural brilliance → lively sparkle without treatment
  • No double refraction → clear, clean appearance
  • Mostly untreated → genuine natural product
  • Pure crystal structure → many stones are surprisingly clear
  • Wide color spectrum

Treatment of Spinel

A major advantage of spinel:
