Yellow Gold Ruby Crown Ring

Ruby is a beautiful, durable, and rare red stone! It is part of the gemstone family corundum, meaning sapphire is its sister! However, this crimson beauty is special. In fact, ruby is the only colour of corundum with a special name. That’s right! All the other colours of corundum – and it spans the whole rainbow! – are simply called sapphire. That is because this red gem is significantly more rare than its sibling.
