About The Rapaport Group

Entrepreneur Martin Rapaport, founder and chairman of the Rapaport Group, began his career in 1975 as an apprentice diamond cleaver in Antwerp, Belgium. In 1976, Martin founded his eponymous company. He soon recognized a need for fair and transparent diamond pricing. In 1978, when he was back in New York City, Martin revolutionized the industry when he published the Rapaport Price List.  He transformed the industry again in 1996 when he launched the online RapNet Diamond Trading Network. Together, RapNet and the Rapaport Price List, provide diamond pricing, availability and trading transparency in a competitive global environment. The largest recycler of diamonds, the firm offers its Rapaport Trading and Auction Services selling over 500,000 carats of previously owned diamonds each year. Over the years the Rapaport Group products and companies have evolved and expanded internationally to include a broad range of added value services with a unified purpose: The development of fair, honest, transparent, competitive and efficient markets.

Martin is an industry activist and leader who advocates for the rights of artisanal diamond diggers. He is one of the originators of the Kimberley Process (KP), a United Nations backed set of requirements instituted to stop the flow of diamonds funding conflict from entering the mainstream market. In 2017 the Sierra Leone government selected the Rapaport Group to market and auction the “Peace Diamond” (left) a 709-carat rough diamond found by a group of artisanal diggers. The Rapaport Group provided its services at no charge so that all of the money made from the sale of the diamond would benefit the artisanal diggers and the people of Sierra Leone.

The Rapaport Group currently employs 230 team members. The company operates offices in major diamond hubs around the world including New York, Las Vegas, Antwerp, Ramat Gan, Mumbai, Surat, Dubai, and Hong Kong.

A romantic at heart, Penina particularly likes helping newly engaged couples find the perfect diamond and setting to create the engagement ring of their dreams. “Diamonds.com is the place that people can come to when they want to acquire quality jewelry from someone they can trust.” Penina specializes in diamonds of 3 carats and above and advises clients who wish to disperse of their family jewels.

Amber Michelle

Chief Curator & Storyteller

It is my desire that everyone experiences the joy of jewelry the way that I do,” says Amber Michelle, chief curator & storyteller for the Rapaport Collection on diamonds.com. For 23 years, Amber was editor in chief of Rapaport Magazine, a business-to-business publication for the diamond, gemstone and jewelry industry. During that time, she reported on everything from mining and gemology to fashion, design, history and auctions at Christie’s and Sotheby’s. “It has been my great pleasure to hold some of the world’s most famous diamonds in my hand and connect to those amazing gems on a deep level. Every diamond and piece of diamond jewelry has its own special tale to tell and when I hold those fabulous gems in my hand they whisper their story to me.” Amber’s love of gemstones came about at an early age. The daughter of a foreign-service officer, she traveled the world extensively and began collecting and studying gemstones for their spiritual meaning. She continues on that journey meditating with gemstones daily. For the Rapaport Collection, Amber combines her love of fashion, art and jewelry to curate a selection of estate and fine diamond pieces with a design point-of- view that appeals to a collector’s sense of history and a woman’s sense of style.
