What is a ruby?

Ruby is red corundum – the same type of mineral as sapphire, but colored red by chromium inclusions. With a Mohs hardness of 9, it is extremely hard and durable. A high-quality ruby of top grade can be more expensive than a diamond of the same size.

Why is ruby so valuable?

• Color is the most important value factor: "Pigeon Blood" (deep, vibrant red) is the most expensive category
• Origin matters: Burmese (Myanmar) rubies fetch higher prices than those from other origins
• Untreated rubies with GRS certification are extremely rare and valuable

Ruby as an engagement stone

No stone symbolizes passion and love as unequivocally as a ruby. Set in yellow gold with diamond pave – a ring that stands out in any room.
