Tanja Manuela Sadow is a Singapore educator and founder of the Jewellery Design and Management International School

Early life and education[edit]

Sadow studied in Spain, the United Kingdom and attended the Gemological Institute of America in the United States of America. Her training included various forms of design and she is a graduate Jewellery Gemmologist.


From 1984 to 1991 Sadow was a resident and extension instructor at the Gemological Institute of America, training jewellers in their Santa Monica campus as well as in 48 US States and conducting GIA's first extension course in Singapore[citation needed]

In 1991 Sadow consulted with the Singapore Economic Development Board,[citation needed] recommending the development of a Singapore-based education facility for the jewellery industry. Later she was commissioned to develop the gemmology curriculum for the newly formed Jewellery Industry Training Centre of Singapore (JITCS). Sadow continued to develop training programmes and deliver gemmology and jewellery training to the Singapore jewellery industry with the JITCS until December 1994.[citation needed]

In 1995 Sadow established a commercial company, JusTanja Pte. Ltd. which she would use to design and distribute jewellery lines in Singapore, Los Angeles and London, stocked by notable department stores such as Harrods of London. Through this company, Sadow also delivered corporate training to Singapore jewellery firms and raised awareness about gemstones and jewellery with Singapore clubs and communities.[citation needed]

Sadow established the retail brand BeadHub. Between 2000 and 2006, Sadow grew BeadHub from a single member only location to a multi-outlet component and finished jewellery chain in Singapore[citation needed] with locations in Wisma Atria, Emerald Hill Road and Sunshine Plaza as well as a unique DIY jewellery concession within Robinson & Co. in The Centrepoint. The BeadHub brand was sold in 2006 following Sadow's desire to pursue the development of a formal training institution.[citation needed]

In 2007 Sadow founded the Jewellery Design and Management International School in Singapore. She continues to head this organization in the capacity of executive director and dean of the school.


Sadow is founder and president of the Guild of Jewellery Professionals and Artisans,[1] a not-for-profit society registered in Singapore, and an executive committee member of the Singapore Jewellers Association,[2] a not-for-profit association registered in Singapore.

Sadow regularly delivers public talks and workshops both in Singapore[3][4][5] and the Asia-Pacific region[6] to promote jewellery appreciation and interest in the jewellery industry. She also works with international brands to provide educational content to support their outreach activities.[7] Sadow also provides authoritative viewpoints for press articles in Singapore and around the world.[8][9][10][11][12][13][14]
