Radiant in Red: Celebrating July’s Ruby Birthstone with McDowells

In ancient India, the ruby was revered as the “king of precious stones” due to its rarity, durability (second only to diamond), striking beauty, and legendary powers. Deeply linked to the life force of blood, it symbolised vitality and strength in Indian jewellery. Over the centuries, many believed the July birthstone could warn of danger or misfortune, while others credited it with healing powers and calming tempers. Burmese warriors thought it granted invincibility, and in medieval Europe, rubies were said to bring health, wisdom, wealth, and love.

Along with being the birthstone for July, ruby is also the traditional gift for celebrating 15th and 40th wedding anniversaries.

The story of the July birthstone begins in Myanmar, home to the famed Mogok region, which has produced prized rubies for over 500 years. Known for their vivid red hue and glowing fluorescence, Mogok rubies remain some of the most sought-after in the world.

Vietnam became a key source in the late 20th century, with the Luc Yen and Quy Chau regions yielding red to purplish-red gems. Mozambique’s Montepuez mines are now a major producer, offering rubies rivaling those from Mogok.

Other notable ruby sources include Thailand, Cambodia, Afghanistan, Sri Lanka, Kenya, Tanzania, and Madagascar.

Rubies are often heat-treated to enhance their red colour and reduce inclusions, a process widely accepted in the trade. Lower-quality stones may undergo additional treatments like dyeing or glass filling, which can affect durability.

Always ask if a ruby has been treated and how, as this can impact both value and care. A GIA Identification Report can confirm whether a stone is natural or treated.

To clean, use warm soapy water and a soft brush. Avoid harsh methods on treated stones.
