Why You Should Add Dark Blue Cobalt Spinel to Your Gemstone Collection

Dark blue cobalt spinel is a rare and beautiful gemstone that has many reasons to be added to your gemstone collection. Here are some of them:

• Dark blue cobalt spinel has an intense and vivid blue color that is comparable to the finest sapphires. The color is caused by the presence of cobalt in the crystal structure, which is a very rare element in nature.
• Dark blue cobalt spinel is 100% natural and untreated, unlike many other blue gemstones that undergo heat treatment or diffusion to enhance their color. This means that the color you see is the color that nature intended.
• Dark blue cobalt spinel is very durable and has a hardness of 8 on the Mohs scale, making it suitable for any type of jewelry. It also has a high refractive index and excellent dispersion, which give it a brilliant sparkle and fire.
• Dark blue cobalt spinel has a rich history and a bright future. It was once mistaken for sapphire and used in royal jewels, such as the Black Prince’s Ruby and the Timur Ruby, which are actually red spinels. It was also revered by the ancient Greeks and Romans as a stone of immortality and love. Today, it is gaining popularity among gem collectors and enthusiasts, who appreciate its rarity and beauty.
