About Wes Carroll

I have enjoyed an extraordinary career in fine jewelry, working for decades in some of the world's most prestigious jewelry houses.  In 2010, I founded WDCIII, Wholesale Diamond Company, which specializes in the buying and selling  of diamonds, colored stones, watches, antique and modern jewelry.

As Director of Cartier, Bulgari, Graff & Chopard, I was able to forge relationships with some of the top stone suppliers and jewelry designers in existence. These relationships have allowed WDC III, Wholesale Diamond Company,  direct access to diamonds, precious and semi-precious gemstones, vintage signed pieces and watches at incredible pricing.  

As a certified Gemologist in diamonds and colored stones, I can assist in finding the perfect piece of jewelry for any occasion. Whether it is a loose diamond, signed piece of jewelry, luxury watch or one-of-a-kind item, my direct contacts allow me quick access to inventory not available to the public. In addition, my jewelers can help design a custom finished piece of jewelry with distinctive style and master craftsmanship in a true collaboration with your desired needs. 

My clients will benefit from the transparency and experience I bring to the buying and selling of fine jewels and watches. This, coupled with my 30 years in the luxury retail and wholesale business, has given me the knowledge needed to best direct your specific requests. Let me use my contacts and expertise to locate your next luxury gift, creating a new memory that will last a lifetime.

WDC III prides itself on providing clients a professional and confidential atmosphere when selling their unwanted jewelry that combines unparalleled expertise, exceptional service and immediate payment. I personally know that selling jewelry can be an extremely emotional experience. Your trust, comfort and confidence are paramount, and I promise to make your selling experience both informative and positive.
