Fascinating Properties and Origins of Diamonds, Rubies, Topaz, and Cobalt

Discover the captivating world of minerals, focusing on diamonds, rubies, topaz, and cobalt. Diamonds stand out as the hardest natural substance on Earth, formed entirely of carbon and originating from depths of up to 200 kilometers. Rubies, the red variety of corundum, are prized not only for their beauty but also for their healing properties. Topaz is commonly found in granitic environments, while cobalt is a lustrous metal celebrated for its historical use in pigments and jewelry. Explore the geological history and unique characteristics of these remarkable minerals.

  2. Diamonds • Diamonds are the hardest natural substance. • They are made completely out of carbon. • Diamonds are up to three billion years old. • Diamond crystallization originates some 200 kilometers, or 320 miles, beneath the surface. • It has a long tradition of invincibility and hence the Greek name, adamas.

  3. Ruby • The gemstone ruby is the red variety of the mineral Corundum, the second hardest mineral known. In healing, rubies are the gem of choice to cure diseases of the blood and the heart.

  4. Topaz • Topaz is commonly associated with silicicigneous rocks of the granite and rhyolite type. It typically crystallizes in granitic pegmatites or in vapor cavities in rhyolite lava flows like those at Topaz Mountain in western Utah. It can be found with fluorite and cassiterite in various areas including Ural and Ilmen mountains of Russia.

  5. Cobalt • Cobaltis a hard, lustrous, gray metal. Although cobalt-based colors and pigments have been used since ancient times for making jewelry and paints, and miners have long used the name kobold ore for some minerals, the free metallic cobalt was not prepared and discovered until 1735 by Georg Brandt.
