Natural Diamonds

A natural diamond is a pure carbon crystalline gemstone formed by carbon, high pressure, high heat, and time beneath the earth's surface.

Diamonds are incredibly tough gemstones, making them exceptional choices for heirloom-quality pieces that are worn frequently. They possess scintillation and optical qualities that make them truly enchanting gemstones.

While lab-grown diamonds can be produced limitlessly, we are limited to the number of natural diamonds the earth has created. The conditions in which natural diamonds have formed beneath the earth’s surface are precise, making these gemstones astounding creations.

 With awe-inspiring origins, enchanting beauty and impressive durability, a natural diamond ring, necklace, bracelet, or custom jewelry creation is the ultimate love letter to your special someone or to yourself.

Natural diamonds that grace engagement rings, tennis bracelets, earrings, and other fine jewelry pieces started as pure carbon deep underground millions of years ago. High pressure and high temperatures caused the classic diamond crystal pattern to grow from pure carbon, resulting in durable stones.

The natural diamonds formed in a layer of the mantle that’s still too deep to reach with today’s mining technology. It's believed that the raw natural diamonds were brought closer to the earth’s surface through rare volcanic events known as kimberlite eruptions in the Cretaceous Period. Had the diamonds found their way closer to the earth’s surface in other eruptions or processes, the slower movement would have caused the diamonds to transform to simple graphite, which is also pure carbon, rather than diamonds.  

But instead, natural diamonds were brought closer to the surface very quickly. This allowed them to maintain their unique crystal structure that sets them apart as sparkling, strong and timeless diamonds. Once these deposits of diamonds were discovered by humans, they became a favorite gemstone worldwide.  

Natural diamonds are woven into the special moments that add a spark of brilliance to life. An engagement, a wedding, a birthday, a major accomplishment —these are significant events that are often marked by a natural diamond.  

While lab-grown diamond jewelry can certainly be used to celebrate milestones, and can be cherished forever, earth-made diamonds are more often intended as heirloom pieces because they usually retain their value better. 

Not all natural diamonds are equal. If you’re in search of responsibly sourced natural diamonds, choose jewelers who adhere to the Kimberly Process. This will ensure that the diamonds are 100% conflict-free.  

Many natural diamonds are graded by their cut, color, carat, and clarity. These qualities are known as the 4Cs of diamonds, which are standardized diamond grading systems used to assess an individual diamond’s important details.  

Trusted institutions like GIA and IGI offer diamond dossier reports of the 4Cs and other qualities of note, making it easy to compare and contrast natural diamonds to find the right fit.
