Diamonds have long been regarded as symbols of love, commitment, and luxury, captivating hearts and minds across the globe. But have you ever wondered where jewelers source these exquisite gems? The journey of a diamond from the depths of the Earth to the sparkling display in a jewelry store is a fascinating tale filled with intrigue, craftsmanship, and ethical considerations. In this article, we will explore the various avenues through which jewelers procure their diamonds, shedding light on the complex supply chain that brings these precious stones to market.

Overview
Jewelers obtain their diamonds through a multifaceted network that includes mining companies, wholesalers, and gemstone dealers. The majority of diamonds are mined from specific regions known for their rich deposits, such as Africa, Russia, and Canada. Once extracted, these gems are often sold in bulk to wholesalers who specialize in sorting and grading diamonds before they reach retail outlets. This intricate process ensures that jewelers have access to a wide variety of diamonds, each with its unique characteristics and price points.

In recent years, the demand for ethically sourced and lab-grown diamonds has surged, prompting many jewelers to reevaluate their sourcing practices. As consumers become more conscious of the origins of their purchases, jewelers are increasingly looking to transparent supply chains that

Sources of Diamonds

Jewelers obtain their diamonds from a variety of sources, ensuring a steady supply of these precious stones for their customers. The primary sources of diamonds include:

  • Mining Companies: Large mining companies operate diamond mines across the globe, extracting rough diamonds directly from the earth. Notable companies include De Beers, Alrosa, and Rio Tinto, which control significant portions of the diamond supply chain.
  • Diamond Dealers: Wholesale dealers play a crucial role in the diamond supply chain. They purchase rough diamonds from mines, cut and polish them, and then sell them to jewelers. These dealers often participate in international diamond trading hubs.
  • Auctions: Some jewelers acquire diamonds through auction houses, where high-quality stones are sold to the highest bidder. Notable auction houses like Sotheby’s and Christie’s host diamond auctions, attracting jewelers and collectors alike.
  • Gemological Laboratories: Certain laboratories specialize in grading and certifying diamonds. Jewelers may purchase certified diamonds from these labs, ensuring that they meet specific quality standards.
  • Synthetic Diamonds: With advancements in technology, lab-grown diamonds have become a viable alternative to natural diamonds. Many jewelers now offer synthetic diamonds, which are often more affordable and environmentally friendly.

Jewelers obtain diamonds from various sources, each with distinct characteristics and implications for quality, ethics, and pricing. The primary sources include:

  • Natural Diamonds: Mined from the Earth, these are the traditional diamonds that have been valued for centuries.
  • Mining Companies: Large corporations such as De Beers and Alrosa operate extensive mining operations.
  • Artisanal Mining: Small-scale miners extract diamonds in less regulated environments.
  • Synthetic Diamonds: Created in laboratories, these diamonds possess identical physical and chemical properties to natural diamonds.
  • High-Pressure High-Temperature (HPHT): This method mimics the natural diamond formation process.
  • Chemical Vapor Deposition (CVD): This technique grows diamonds from a gaseous state.
  • Recycled Diamonds: These are diamonds that have been previously owned and are recut or repurposed for new jewelry pieces.

A designer by training, a storyteller at heart, and someone who’s always been fascinated by the quiet power of what we choose to wear.

The original Growing Jewelry collection was my attempt to bridge nature and design. I crafted rings that held real moss, asking wearers not just to display them but to care for them.

At first, it was about playfulness and poetry. But as those little green rings made their way into the world, people reached out. And the questions they asked went far beyond moss.

Because jewelry isn’t just sparkle. It’s story, symbol, and self expression and it deserves to be understood as much as admired.

So, if you’ve ever wanted to know why a ruby means passion, or how to keep your silver bright, or what your great-grandmother’s brooch might say about the era she lived in you're in the right place.
