Ruby

Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire.

Ruby can command the highest prices of any colored gemstone. The per carat prices of fine-quality rubies have been rising consistently, many times breaking auction records.

Color is the most important quality factor for Ruby

Ruby value depends on how visible inclusions are.

A ruby's crystal shape dictates its suitability for certain cuts.

Fine-quality rubies over one carat are very rare.

A technical report for Montepuez Ruby Mining (MRM) estimated a life of mine plan to produce about 431 million carats of rubies (including 5.8 million carats of “premium” ruby), with forecast gross revenue of about USD 5.96 billion over the life of mine.

The Montepuez Ruby Mining (MRM) operation in Cabo Delgado is the largest ruby mine in Mozambique and one of the largest in the world. A 2024–2025 expansion project will triple MRM’s processing capacity from 200 to 600 tons of ore per hour, allowing processing of an estimated 1.48 million tons of ruby bearing ore and significantly increasing potential output.
