Spinel on the rise

Termed “the great impostor,” for hundreds of years it was believed that spinels and rubies were the same stone. With a rich color that is described as “stoplight red” even experts couldn't tell the difference. In 1812 Friedrich Mohs published the scale which is used today to define the relative hardness of gemstones. Ruby (corundum) was identified as a 9, while spinel was 7.5 to 8.

Spinels were used in jewelry throughout the 1800s and early 1900s, but it was now perceived as a Class B gem.
One of the rarest hues found in spinel is a cobalt blue Vietnam natural spinel. Spinels were often known as ‘Balas ruby,’ a name probably derived from the North Indian region of Balascia (or Badakshan.)” The finest spinels display a bright, vitreous luster. Those that exhibit a strong, even, perfectly saturated hue are most prized. When expertly cut, they exhibit brilliance and exceptional clarity. While a ruby might go for $40k a carat, a spinel of the same size and quality would garner $1k to $7k a carat.
The spinel is now called “the collector’s gemstone”or “a connoisseur’s stone.”
