After years of traveling the world in search of flawless gems, Osnat Gad began designing her own jewelry collection in the early 1990s.  By 1992, OGI (Osnat Gad Inc.) was unveiled, offering exquisite fine jewelry.

Designed and expertly crafted in New York, every OGI piece is created from the finest materials. From timeless bridal sets to OGI’s vibrant stackables and stylish fashion pieces, every gemstone is hand selected for high quality and brilliant color.

Fashioned in platinum and 18K gold, OGI offers a diverse collection of styles to choose from.

OGI has received much acclaim throughout the years, winning top industry honors and garnering international praise for innovation in jewelry. Today OGI is well established in the bridal industry, sold in over 250 stores worldwide.

With jewelry that shines brightly on your wedding day and everyday after, OGI creates stunning jewelry for every moment of your life.


OGI maintains the highest standards in design, materials and craftsmanship. These strict standards ensure the longevity of our product, so that our jewelry may be passed down from generation to generation. 

OGI’s team of graduate gemologists carefully hand-select every diamond and gemstone, while our experienced designers masterfully craft each piece in precious metals.   OGI strives to uphold the highest levels of quality and craftsmanship with every finished piece.

All OGI jewelry is expertly crafted in the USA, and we do not use conflict diamonds.  OGI’s trademark guarantees the finest quality of jewelry; look for the OGI stamp and accept no substitute. 


With over three decades of experience in the jewelry industry, Osnat Gad is an expert in precious gemstones and bridal jewelry.  Born into a male-dominated jewelry dynasty, Gad forged a path of her own when she launched Osnat Gad, Inc. over 27 years ago.  She traveled throughout the world, searching for rare gems in exotic locales from Sri Lanka to Columbia, and quickly established herself as a prominent dealer in precious gems.

In 1992, Gad expanded her business to include jewelry design and manufacturing under the OGI Ltd. brand.  Today OGI Ltd. is renowned in the bridal industry and boasts over 250 clients, including Nordstrom, Neiman Marcus and Saks Fifth Avenue.  As the founder and CEO of OGI Ltd., Gad continues to design exquisite, modern jewelry including wedding bands, engagement rings, earrings, necklaces and bracelets.

In November 2004 Osnat Gad became a published author, with her book Wedding Rings. Published by Stewart, Tabori & Chang, the book traces the history and romance of the wedding ring - the perfect symbol of eternal love - from ancient Egypt to today.

The concept for Osnat Gad’s next venture was born when she searched for the perfect evening clutch to wear to a red-carpet event in the fall of 2004, and was sorely disappointed.  As she explains, “ I wanted a bag that would stand out next to an exquisite piece of jewelry.”  Utilizing her expertise in the jewelry industry, Gad set out to create an evening bag suitable to wear with lavish jewelry.   One year later the Ocie Minaudière collection was unveiled, flawlessly incorporating precious stones into a fashion staple, the evening bag.

Based in New York, Gad continues to oversee the OGI Ltd. and Ocie brands.
