With its deep red, the ruby has for centuries been regarded as the stone of courage, strength and passion; it has long been known as the stone of kings and commanders. In this guide we explain the meaning, benefits, zodiac affinity and care of ruby in plain language.
What is a ruby?
Ruby is the red member of the corundum family; it takes its vivid red from the chromium in its structure. The other colors of the same family are called “sapphire” — so ruby and sapphire are in fact sibling stones, the only difference between them being color.
Its hardness is 9 on the Mohs scale; it is one of the hardest natural stones after diamond. This durability makes ruby both precious and resilient enough for everyday wear.
