The King of Gems: Investing in Ruby, July's Rare and Undeniably Powerful Birthstone

Durability and Investment: The Power of Corundum
Like its sibling Sapphire, Ruby is composed of corundum and scores a 9 on the Mohs Hardness Scale. This makes it one of the toughest natural stones available, second only to diamond.
Ruby is an exceptional choice for engagement rings and heirloom jewelry, capable of withstanding generations of wear without showing significant damage.
The Color Premium: Chasing "Pigeon's Blood"
The value of a Ruby is almost entirely dependent on its color.
The most sought-after hue is "Pigeon's Blood"—a vivid, intense, slightly purplish-red with a soft, glowing fluorescence.
Honest Advice on Treatment
Over 90% of Rubies on the market have been heat-treated.
- This is a permanent, industry-standard process that improves color and clarity.
- You should expect this.
- If a seller offers an unheated Ruby with excellent color, be prepared to pay a massive premium, as these are true collector items.
The Buying Guide: Sizing and Clarity
High-quality Rubies over 1 carat are extremely rare.
Unlike diamonds, flaws and inclusions (often called "silk") are common in Ruby. Minor inclusions are acceptable and can even prove its natural origin.
When comparing options:
- Prioritize Color: A rich, intense red is more valuable than a slightly larger, pale stone.
- Look for Brightness: Ensure the Ruby doesn't look dark or muddy; it should glow with fire.
Our Recommendation: A Classic Statement Ring
A Ruby ring is the ultimate statement of lasting passion.
- Opt for a simple four-prong setting in yellow gold, which beautifully complements the stone's red fire, or a halo setting for extra protection and sparkle.
