Unheated Mozambique Ruby vs Heated: Which is Better?

When choosing a Mozambique ruby, deciding between unheated and heated options is crucial. Each type has its own unique features, value, and appeal. Let's compare them to see which is better for you.

Unheated Mozambique Ruby

Unheated Mozambique rubies are highly valued because they are natural and untouched. These rubies have a deep red color, excellent clarity, and a well-defined cut. They are rare, which makes them more expensive than heated rubies. In fact, less than one percent of all gem-quality rubies remain untreated.

Features:

• Color: Unheated Mozambique rubies have a rich, deep red color.
• Clarity: They often have natural inclusions called “silk,” adding to their authenticity.
• Price: Due to their rarity and natural beauty, unheated rubies can be quite expensive. For example, a high-quality unheated ruby can cost up to $35,000 per carat, compared to $12,000 per carat for a similar heated ruby.

Investment: Unheated Mozambique rubies are a great choice if you want a unique gem with long-term value. Their rarity and natural beauty mean they tend to increase in value over time.

Heated Mozambique Ruby

Heated rubies are more common and usually less expensive. Heat treatment improves a ruby’s color and clarity, making them more attractive and affordable.

Features:

• Color: Heat-treated rubies can have a more yellow or orange hue compared to the rich red of unheated stones.
• Clarity: Heating often reduces visible inclusions, making the ruby look more uniform.
• Price: Heated rubies are generally cheaper and more available. They still offer great beauty at a lower cost.

Durability: Heat treatment is stable and doesn’t discolor over time or get easily damaged.

How to Tell the Difference

The easiest way to tell unheated from heated rubies is by their color. Unheated Mozambique rubies have a rich red hue, while heated ones may look more yellow or orange. A high-powered microscope can reveal tiny bubbles or inclusions that indicate whether a ruby has been treated.

Conclusion

Both unheated and heated Mozambique rubies have their own benefits. Unheated Mozambique rubies are perfect for those who want something rare and valuable. Heated rubies offer a beautiful and affordable option. Your choice depends on your preferences, budget, and purpose.

By understanding the differences, you can make an informed decision and find the perfect Mozambique ruby for you.
