NEW YORK – Jewelry designer David Jerome has spent much of his life, traveling the world, amassing a breathtaking collection of the rarest and purest rubies, aquamarine, tanzanites, emeralds and sapphires. The David Jerome Collection is formed of hundreds of prized gems.

As a boy growing up in London, Jerome was fascinated by color and would spend hours staring at the pieces of jewelry his father would bring back from a local street market, mesmerized by their deep and vibrant hues.

In the 1970s Jerome started to build his first career, as a hairdresser. This profession fed his love of color and creativity. Working alongside the likes of famous stylist Vidal Sassoon, Jerome became known for his colorful and creative hairstyles and would experiment with different hair salon products to discover new and vibrant colors. This eventually led to Jerome starting his own company, alongside his brother, in the United States, called Jerome Russell.

From that moment on Jerome could pursue his dreams full time, which led to him finding his way back to his love for precious colorful gemstones that he had established as a boy. Jerome would go on to be educated in the realms of gemology, ensuring he could realize the quality of the gemstones he would go on to purchase.

All precious gemstones within the David Jerome Collection were originally sourced as loose gems. In recent years the gems have been set and mounted among diamonds, in pieces of fine jewelry, to highlight and showcase their beauty as well as make them a more suitable offering for the international jewelry market. The owner of this private collection has traveled to the world’s precious stone mines, not limited to but including Myanmar, Sri Lanka, Zambia and Tanzania where Jerome has sorted only the highest quality stones. Over the years Jerome has become established and recognized by gemstone miners across the globe as one of Europe’s most prominent buyers.
