Large jewelry houses Bvlgari, Cartier, Tiffany have long been using noble spinel in their products, but in Russia, with rare exceptions, spinel is slightly biased. But in vain, the stone is actually incredibly cool.
Spinel is usually not processed in any way except for cutting. The stone is by its nature bright and clean, requiring no improvement. Colors to suit every taste: red, blue, grey, yellow, green, blue... Continue the list?
Despite the fact that spinel mining is quite stable and there are many deposits, the cost of the stones is rising. Rare colors Electric blue, Mahenge, Jedi have increased 7-10 times over the past few years. A better investment than these cryptocurrencies of yours.
And the main thing is the correspondence between price and quality. The number of rubies is steadily going down, and their value is flying into space. If you are not a collector and not a billionaire rolled into one, then a pigeon's blood ruby, costing over $100,000 per carat, is unlikely to be available to you. But an equally juicy red spinel starting at $1,000 per carat will fit perfectly into jewelry and will gain in value, although slower than a ruby.
