Founded in 2007, JDMIS is Singapore’s only specialized jewellery school that specialises in and provides end-to-end jewellery education. The school is led by founder and dean, Mrs Tanja Manuela Sadow, an award-winning designer and highly accredited renowned jewellery educator with more than 30 years of experience across the United States, United Kingdom, and Singapore. Since its establishment 15 years ago in Singapore, JDMIS has trained over 25,000 individuals and certified over 5000 students across 56 countries, as well as top local and international brands.

The Jewellery Design and Management International School (JDMIS) provides education and inspiration by means of specialised academic programmes in jewellery design, trends, marketing & management and professional skills training in traditional and new technologies for the practical manufacturing of creative, designer jewellery. Its programmes focus on developing participants’ artistic abilities, applied skills and business acumen, in-line with the needs of the industry. JDMIS trainers are experts in the skills they teach and follow a structured and up-to-date curriculum and share their comprehensive experience as practicing jewellery professionals.

The school’s Diploma programmes produce an enterprising new breed of contemporary jewellery designers who will develop into entrepreneurs or become qualified professionals primed for success in the corporate jewellery industry. JDMIS’ unique diplomas and advanced diplomas can be completed in as little as two months of intensive study, or part-time according to flexible weekday, weekend or weeknight schedules. This flexibility extends beyond graduation, and alumni enjoy the ability to return and ‘refresh’ their skills without additional training costs.

For industry professionals and independent designers, JDMIS provides shorter, yet comprehensive Certificate courses in a variety of practical and business-related topics. All JDMIS courses are modular, ideal for students who want to pick up a specific skill in a short workshop and still have the option for that learning to contribute towards their educational goals of a comprehensive jewellery qualification.

In addition to its formal educational offering, JDMIS specialises in customised corporate training for the jewellery industry as well as unique jewellery-related team-building workshops for corporations; its corporate clients include top multinational jewellery and fashion brands as well as local chain and boutique retailers. The school also enjoys collaboration with many facets of the jewellery industry including a leading-edge Jewellery Manufacturer.

JDMIS Tanja Sadow

Tanja Sadow is not only the most sought-after jewellery expert in the region, but a renowned educator, an international award-winning designer, and a successful businessperson. Today, she is Dean of the Jewellery Design & Management International school and maintains an intercontinental designer jewellery label ‘JusTanja’ with prominent outlets such as Harrods of London, she has built a thriving retail business in Singapore and established an educational organization to foster the Jewellery community she has built around her passion: Gems & Jewellery.

Tanja began her 30-year involvement with jewellery-making at the Gemmological Institute of America, where she studied and later taught, specializing in jewellery manufacture, design, and gemmology. Tanja lectured throughout the United States and in 1990 was invited to Singapore to assist the Economic Development Board as a consultant on a project entitled: “Enhancing Creativity in Jewellery Design”.

Based on her recommendations, she later developed a Gemmology curriculum for the Jewellery Industry Training Centre of Singapore. She has been involved in educational projects with Louis Vuitton, Tiffany & Co., Harry Winston, Mabbousin, B.P. de Silva, Swarovski, and many other local and international brands. Over 17,000 students, in Singapore and world-wide, have benefited from Tanja’s expertise and knowledge.

Tanja has long recognized the value of education and accreditation and in 1995 she established JusTanja Pte. Ltd. with the objective of educating industry professionals and enthusiasts in silver jewellery-making and the Creative Jewellery Arts. In 1998, seeing the need for a reputable retail source for the natural materials and metal components used in high quality fashion jewellery, she founded BeadHub, Singapore’s premiere source for Jewellery-making components. In 2007 Tanja sold BeadHub to focus her attention back towards education.

Today, through the Jewellery Design & Management International School, Tanja offers formal Diploma and Advanced Diploma education, professional certification for the jewellery industry and workshops, courses, and seminars on all aspects of jewellery-making. In the past year alone, Tanja and her team have taught extended programs to over 5000 students, more than 500 of which have progressed beyond the diploma-level and have already launched their own careers in jewellery.

In 2012, Tanja and the JDMIS were awarded the Small and Medium Business Association’s Promising SME 500 award for the growth and quality standards they achieved.

Tanja continues to travel the world, teaching, learning and constantly building awareness and recognition for the JDMIS and her Guild of Jewellery Professionals and Artisans.

The Phenomenal Gems & Jade class is taught by Tanja. It really was phenomenal as I’ve never been so close to some of these glittering stones, let alone touch and study them! I learned how to tell which gems were natural and which were man-made too!
