National Gem Cut©

Virtu Gem is pleased to bring you The National Gem Cut©, a gemstone facet design developed by gem cutters across Kenya, Malawi and Zambia to honor and represent each of their nations through the art of gemstone design and cutting. Virtu Gem held workshops led by Prof. Dr. Adriano Mol which culminated in three unique and branded facet design’s.  Kenya’s Cheetah head,  Malawi’s Mbuna and Zambia’s Eagle.  The concept behind each representational facet goes deep into the heritage and symbols of pride for the respective countries.  The National Gem Cut© promotes inclusion and equity in the gem stone trade by elevating gemstones cut in source countries.

    Viviana Langhoff

    Viviana Langhoff’s work is centered on the idea of heirloom. “Jewelry history, ancestry, and storytelling are all often focused around objects; I’ve always wanted to design work that is elegantly pushing design forward while drawing on our past.”

    Viviana established her point of view in the realm of fine jewelry after studying conceptual design at the School of the Art Institute. She continued her education in metalsmithing at Columbia College while simultaneously working under both fine jewelers and contemporary art jewelry makers. She’s now been working in design under her own name for over 10 years, creating custom fine jewelry, interiors, and decorative objects.

    Viviana is known for her intricate vintage-inspired metalwork, modern bridal styles, and one-of-a-kind pieces featuring unexpected hues, antique stones, and historical references. Borrowing from the worlds of fine art, cultural adornment, and design, her custom work appeals to the expressive and open-minded individual— those who value individuality, creative collaboration, and are unafraid to stand out.

    Viviana’s pieces can be found along 50 other artists’ work at her jewelry store, Adornment + Theory, in the Chicago neighborhood of Logan Square. When not working with custom clients and jewelry, Viviana can be found hosting gatherings, gardening, traveling, and spending time with her partner and two chubby pups.

     I believe the most important question everybody should ask regarding what goes into jewellery is “who benefits from this?” I feel it’s my job as a journalist to educate the consumer – and jewellers – on what to ask when buying jewellery and the materials that go into its making.
