What separates a ruby stone from a pink sapphire? It comes down to how intense the color is. The deeper the red, the more likely it’s a ruby. If it shifts toward pink, it becomes a sapphire. Gem labs use color traits to make this call—and we’ll explain how.

What is Pink Sapphire?

Pink sapphire comes from the mineral corundum, the same mineral that forms ruby and sapphire. The pink color forms due to trace amounts of chromium in the crystal.

These stones are mined in places like Sri Lanka, Madagascar, and Myanmar. They form naturally in metamorphic rocks, under intense heat and pressure.

Symbolism

Pink sapphire is often seen as a symbol of love, wisdom, and loyalty. In some cultures, it’s linked to inner peace and emotional strength. Its softer color gives it a more subtle and calming appeal than ruby’s bold red.

Physical Properties

Just like ruby, pink sapphire rates a 9 on the Mohs scale, making it one of the hardest precious gemstones. That makes it ideal for everyday wear, especially in sapphire jewelry like engagement rings. It’s also highly resistant to scratches, right behind diamond in hardness.

Rarity

Pink sapphires are less rare than high-quality rubies, especially those with vibrant red color. But not all pink sapphires are common. Deep pink stones with even color and clarity are still considered rare and highly valued.

Price

Because they are more available, pink sapphires usually cost less per carat than rubies. But price varies based on tone, clarity, origin, and saturation. A beautiful pink stone from Sri Lanka with high transparency can still command a high price.

What is Ruby?

Ruby is a precious gemstone formed from the mineral corundum. Its vivid red color comes from the presence of chromium during formation.

This element replaces some of the aluminum atoms in the crystal, creating the gem’s rich hue. Rubies are typically found in metamorphic rocks and are mined in countries like Sri Lanka, Myanmar, and Mozambique.

Symbolism

Rubies have long symbolized power, passion, and protection. Throughout history, they were worn by royalty and warriors for strength and courage. In modern times, they’re associated with love, vitality, and success.

Physical Properties

Ruby ranks 9 on the Mohs scale, just below diamond, making it one of the hardest natural gemstones. It resists scratching, making it ideal for everyday jewelry. Structurally, it shares the same mineral base as sapphire—aluminum oxide—but gains its color from trace chromium.

Rarity

Rubies showing intense, consistent red with minimal inclusions are rare. Stones with pigeon blood red color and high clarity are among the most valuable and scarce in the gemstone market.

Price

Ruby prices vary by origin, clarity, cut, and most importantly, color. Stones with high saturation and a strong red hue command premium per carat rates. Rubies from certain regions, like Burma, often carry higher values due to their vivid tone and legacy.

Ruby and Pink Sapphire: Price and Jewelry Use

Price Differences

Main Reasons Rubies Cost More:

• Rarity of pigeon blood red and pure red shades
• High demand in both luxury and investment markets
• Cultural value in markets like India (known as Manik)

Why Pink Sapphires Are More Affordable:

• Less rare than rubies, though still valuable
• More supply from places like Sri Lanka and Madagascar
• Reclassified pink rubies often become pink sapphires, lowering price

Note:

Even small iron or titanium impurities can affect value. Gems with duller tone or low color saturation are priced lower—regardless of type.
