Why jewellery?

Jewellery enjoys a unique selling proposition across the world, given its relevance for everyday wear and importance in cultural representation. Part fashion and part investment, jewellery is by far the most significant contributor to global sales of personal accessories and is worth more than half of the 500-billion-dollar luxury industry. This sector is still growing annually, with the value of the global jewellery market expected to increase at nearly double the growth rate of other segments in the luxury market.

On top of the exciting growth opportunities in the market, jewellery is such a happy industry to be in. Celebrating some of the most significant occasions in people’s lives, jewellery designers and jewellers work with customers to create sentimental gifts, and connect with their clients in ways that no other product can. Furthermore, there are many perks to becoming a jeweller – jewellery has high intrinsic value, and slower and easier-to-manage fashion trends compared to clothing. There is also a ready market for unique, one-of-a-kind pieces. Beyond that, jewellers get to enjoy working with many new and interesting raw materials, cool tools, and even travel all over the world to source for quality materials or meet clients.

Individuals who like working with their hands or enjoy having direct connections with their customers will definitely find significant satisfaction in joining the jewellery industry. If you are someone who is creative, appreciates quality and luxury, and possesses an entrepreneurial spirit, then jewellery is for you!

The career prospects in this multi-faceted industry are diverse. Equipped with proper jewellery training, there are many paths you can choose to follow such as:

  • work as designers in the jewellery industry
  • enter and win International competitions
  • provide freelance design consultations
  • design jewellery before making it themselves
  • develop their own brands and jewellery lines

From a life of monotonous work shifts amongst machines to erratic hours with shimmery gemstones, Ernest Yeo took a leap of faith from being a broadcast engineer to being a jewellery designer. One might wonder how he could change to such a different industry, but jewellery was not new to him: at a young age he was always captivated with anything that sparkled and glittered. After graduating from JDMIS, Ernest founded his own jewellery brand and later worked for one of the most well-known global luxury brand in Singapore.

  • Diploma FAQ: I already have a business degree/experience with jewellery fabrication - can I get credit for some diploma modules? +

    The answer to this question depends on the courses you have completed, your transcripts and/or proven abilities. In principle, the JDMIS does not want to force its students to sit though courses in subjects with which they are already proficient; we are concerned about placing our students in advanced classes if they do not have an adequate foundation - as such it is our policy to review each request on its own merits.

    Make sure you identify the modules you would like to receive credit for in your application form and provide as much supporting information as possible. Our admissions board will review all requests individually and reply within 4-8 working days.

  • Diploma FAQ: How much do the courses cost? +

    Our diplomas cost between SGD 10,800 to SGD 12,800, inclusive of GST, registration and application fees. Our pricing policy is such that we include all tools and materials you will need to complete your coursework.

    Your only additional costs are for materials you intend to use in your self-study or personal projects. Furthermore, the tools you receive as part of your course are yours to keep - our students leave our diploma courses with the skills and equipment they need to create unique and high quality jewellery.

    For more information about the price breakdown of our Diplomas, please click here

  • Diploma FAQ: How can I pay for the diploma course? +

    For application and registration fees, we accept many payment methods, if you want to pay over the phone the head office can accept Visa & Mastercard. If you visit the office, they can take any credit card, NETS or Singapore dollar cheque. If you use internet banking, we also accept local bank MAPS transfers and international wire transfers.

    Foreign students are required to may their tuition payments to a third-party escrow service provider authorized by the Consumer Association of Singapore. This escrow payment is a requirement for the issuance of Student Passes by the Singapore Immigration & Checkpoints Authority and provides additional protection for students. Complete details of the escrow payment process are provided upon your admission to the JDMIS together with your letter of acceptance.

    For Singaporean students or permanent residents, escrow payment is also an option (and is recommended for the additional prodection it provides) however it is not required. Regardless of your choice to use escrow, for your tuition fees, the JDMIS recommends TCC, a local credit union that provides very competitive educational loans. If you would like more information on this we can email you their details or ask one of their credit consultants to call you. Alternatively you can approach your bank and ask them about educational loan programs. They will typically disburse payment upon completion of a credit check and receipt of your letter of offer from the JDMIS; this process can take up to 3-4 weeks so be sure to apply early.
