Natural diamonds have been a symbol of luxury and love for over 500 years since the first recorded diamond engagement ring was presented by Archduke Maximilian of Austria to Mary of Burgundy. Renowned for their rarity, strength, and beauty, diamonds are still a favored choice for engagement rings. Understanding their formation, value, and ethical sourcing is crucial for informed purchasing decisions.
Formation of Natural Diamonds
According to Kristina Buckley Kayel of the Natural Diamond Council, natural diamonds are a crystalline form of pure carbon, created under extreme heat and pressure deep within the Earth. Formed 1 to 3 billion years ago, these diamonds are some of the oldest substances that can be owned. The presence of other elements during formation can result in various colors in diamonds, known as ‘fancy colored’ diamonds. For instance, natural blue diamonds form in areas with boron, and green diamonds near uranium deposits with radiation.
Attributes and Grading
The value of diamonds is assessed based on the four Cs: cut, color, carat weight, and clarity. Unique characteristics, or ‘birthmarks,’ resulting from the formation process can give each diamond a distinct appearance and story. These attributes contribute to the diamond’s individual character and value.
Value and Rarity
Natural diamonds are rare, especially compared to lab-grown diamonds which can be produced in a few weeks. Their rarity stems from the billions of years required for their formation and the finite supply. Only about half of the mined diamonds are considered high enough quality for the diamond market, adding to their value.
Purchasing Considerations
When buying a diamond, Olivia Landau of The Clear Cut recommends seeking stones with certifications from recognized institutions like the Gemological Institute of America (GIA). It’s important to understand that diamond grading involves human assessment, making it as much an art as a science.
Ethical Sourcing and Sustainability
The diamond industry has made strides in ethical sourcing and sustainability. The Kimberley Process, developed by the United Nations and the World Trade Organization, ensures that diamonds are conflict-free. Over 80 countries participate in this process. Furthermore, blockchain technology is being used to trace the journey of diamonds from the mine to the consumer.
Major companies in the diamond industry are also setting timelines for achieving carbon neutrality and actively protect the biodiversity around mining sites.
Heirloom Quality
Natural diamonds are considered a sustainable choice due to their durability and potential to be passed down through generations. Their heirloom quality, coupled with the finite supply, suggests that they can appreciate in both sentimental and financial value over time.
