Shop Rene Escobar
Rene Escobar is a proud third-generation jeweler. His company, Rene Escobar Jewelry, is based in South Florida. Rene is committed to authenticity, originality, and the endurance to the beautiful art of hand-made jewelry.
Rene’s love affair with the world of jewelry began at an early age. The fascination of watching his father, a master craftsman, create intricately beautiful pieces quickly developed into a passion. In the early 1980’s amidst the uncertain social climate of his native Nicaragua, Rene was sent to South Florida to attend college in order to pursue an education unavailable to him in his home country. However, his innate attraction to the art of jewelry making impelled him to seek out a career as a goldsmith.
Jewelry making is in his blood, but his passion is personal, he got his first position as a jeweler when he was seventeen. For the next few years, Rene had the good fortune of working alongside some of the most skillful jewelers in South Florida allowing him to refine his craft. In the early 1990s, Rene formed Rene Escobar Inc., a studio, where for nearly twenty years, he created one-of-a-kind pieces for some of the finest collectors throughout the southeastern United States.
As a private jeweler Rene has always drawn inspiration from keenly observing his clientele, in 2008 motivated by these clients, he created a collection of 18K gold, diamonds and colorful gemstone earrings, that he exhibited for the first time at The Jewelers of America Summer Show in New York City, the collection was a success, since then his collections have been attracting art galleries and select jewelry stores.
Rene’s collections are always evolving, always hand-made in his South Florida Studio using recycled precious metals, set with responsibly sourced gemstones,employing traditional and cutting edge jewelry-making techniques. He and his life partner hand-create each of Rene's jewelry collections.
His clientele embraces Rene’s belief that each individual piece of jewelry is in its own essence a work of art.

Every piece from the Kate Maller collection is handmade jewelry crafted in our studio in Denver, Colorado. We use only recycled high-quality precious metals, and reclaimed or ethically-sourced diamonds and gemstones while crafting our unique jewelry. We’re deeply committed to the preservation of natural resources, and adhere to the highest standards for sustainability in jewelry making.
Kate designs and creates at least two unique + sustainable jewelry collections every year. Diamonds feature prominently in the collections. Diamonds are the hardest stone in the world and because they never erode, diamonds make an ideal heirloom—and their beauty is extraordinary.
Kate Maller Jewelry features fine handmade jewelry for men as well as women. The first KMJ men’s line debuted in the Slice Collection for Men and Women in 2019. In 2020, Kate designed and introduced the first-ever KMJ contemporary bridal line, called The Legacy Collection.
