Owner of the Denver Diamond Buyer

Learn Why Clients Sell Us Their Diamond Rings

Carl Blackburn is owner of Denver Diamond Buyer and among the country’s top luxury estate buyers. As Colorado’s premiere diamond jewelry buyer, he is a recognized specialist in the purchase of important estate jewelry, diamonds, collectable timepieces, as well as a consumer advocate for fair and ethical business practices among jewelry buyers.

Carl is unique among Denver diamond buyers in that he is both a veteran estate jeweler and internationally-recognized designer of diamond jewelry. He has deep knowledge of the estate jewelry market, having started his career in the early 1990’s as a sales representative for his father, a successful California estate jeweler. During that time he traveled throughout the United States, visiting the finest estate jewelry stores and galleries in the country.

Starting in 1994, Carl began regularly traveling to Asia to source diamonds, precious gemstones, and fine jewelry. He then moved to Thailand in 2001 to establish a fine jewelry manufacturing studio in the heart of Bangkok’s jewelry & gemstone district.

Within a few short years Carl Blackburn fine jewelry was featured in jewelry industry magazines around the world-including North America’s Modern Jeweler and Canadian Jeweller, Europe’s Le Bijoutier and Basel Magazine, and Asia’s Tokyo Jewelers and Story.

Fashion trend magazines also took notice with Blackburn’s jewelry featured in publications such as Harper’s Bazaar (Asia) and Better Homes & Gardens (USA) Weddings Issue.

Carl Blackburn’s platinum and diamond jewelry was celebrated for its high attention to detail and classically inspired styling. In addition, Blackburn was becoming recognized along with jewelry designer John Hardy as a vocal advocate for sustainable luxury–writing widely-read articles such as “In Defence of Luxury” for Solitaire & SolitairePro magazine.

Much of the Carl Blackburn fine jewelry developed during this period became what is currently known as the Beverley K Collection, one of the United States’ best-selling fine jewelry collections. All of this professional experience has now made Blackburn one of the most sought-after buyers of estate diamonds and jewelry in the country.

With Blackburn’s worldwide network of estate jewelers and individual collectors, he is able to get clients the most cash possible when it’s time to sell diamond jewelry or sell an engagement ring.

In 2011, Carl made news when he acquired a stunning and rare Van Cleef & Arpels pendant with matching earrings. The hand-crafted platinum set featured multi-carat flawless and internally flawless diamonds and pear-shaped mixed-cut emeralds.

Fine jewelry and diamonds with six figure appraisal values usually are sold at auction houses like Christie’s or Sotheby’s. However, Carl is recognized as one of the few jewelry buyers in the country who can be trusted to make fair and immediate cash offers for high-value jewelry assets. It is a testament to Blackburn’s reputation as a jewelry buyer that so many owners of rare estate jewelry and diamonds choose him as their personal jewelry buyer.
