Master Dynamic Limited (MD) was set up in 2011. MD, Based in Hong Kong Science Park, first applied precision engineering to develop precise and high-quality watch movement and silicon based hairspring, and then pioneer a novel diamond nano-marking technology for the diamond industry. Lately, the company is extending its applications to hybrid artificial intelligence and data analytics, living up to its ethos of creating a better world. It has a team of about 100 engineers, software developers and researchers who put their heads together in material analysis, nanotechnology, precision engineering, retail automation, AI and data analytics. It has more than 100 invention patents granted.
MD devotedly focuses on the foresight of its innovative technology development. To ensure that its research and development projects reach internationally recognised levels, MD works very closely with top universities around the world in different partnership programs. That how to deliver the technology to the end users is also one of keys of MD’s success. In 2015, Goldway Technology Limited (GW), which was derived from MD, officially entered the market to provide technical solutions for the diamond and luxury goods industry. Subsequently, AI Gaspar Limited (AIG), which belongs to the same group as MD, was established in 2018. AIG is dedicated to further enhancing customer competitive advantage and differentiation through hybrid artificial intelligence (AI) and Internet of Things (IoT) technology.
Silicon hairspring benefits watchmaking
Silicon hairspring, a key part for watches, is the first major invention of MD in 2013. It uses silicon and is manufactured with precision engineering and nano technology. Compared to metal hairsprings, silicon hairsprings are better at withstanding temperature changes, shock and magnetism. Watches made with silicon hairsprings are thus more durable and reliable.
At present, only a handful of watch manufacturers have the capability to develop and produce silicon hairsprings. MD is the only manufacturer outside of Switzerland that has mastered this technology, and it holds patents of the technology. Local watchmakers can tap into the supply of such parts in bulk, thus reducing their reliance on overseas suppliers to gain greater autonomy in production and enhance their competitiveness globally.
Nano-marking changes industry practice
Later, MD and GW jointly apply its precision engineering prowess to jewellery industry. It has developed an all-new diamond marking and application technology in partnership with Chow Tai Fook Jewellery (CTF) , and is applying it to overhaul entrenched practice in the diamond business.
The technology involves using patented technology to create a nano-marking on diamond table. This can only be done with advanced nanotechnology and customised precision equipment, which makes it difficult for counterfeiting the mark. The Gemological Institute of America (GIA) has certified that the nano-marking does not change the integrity and 4C (diamond colour, cut, clarity and carat weight) of a diamond, unlike laser marking technology, and this will give consumers greater confidence when evaluating diamonds.
CTF Jewellery has used the technology to launch the T MARK diamond brand since 2015. Each T MARK diamond has a nano mark and unique number. Used in conjunction with the high-resolution computerised optical microscope also developed by GW, customers can track and manage the entire journey of a diamond – from procurement to finished product to purchasing and gifting it – and enjoy greater sourcing and quality assurances.
Diversified nano-marking
With long years of research and continuous development, GW has mastered the technology in finding the best balance between creating marking on diamond table while still preserving its intact quality. Conventional diamond marking is usually done with a micro-laser beam to etch a microscopic inscription on the diamond girdle, yet it carries no differentiation with other technology and is extremely low cost to reproduce. This implies people without much technical expertise could do so thus provides low values in anti-counterfeit purpose. GW has successfully developed series of avant-garde anti-counterfeit marking technologies which are to etch mark on diamond table surface. The marks created are in nano-size, have high opacity, and do not constitute a visual flaw, nor do they affect the diamond colour and clarity.
Not only satisfied with technology development, GW has dedicated to bringing up the production process to live, all processes are sophisticatedly planned. On one hand the process has extremely complicated threshold for copy while on the other hand, it is convenient enough to support simple logistics and short turnaround time. GW’s stable and diversified products and services are patent protected and always at your service.
Variety of QC devices
Patented nano-sized diamond marks can easily show the identity of diamond. On one hand, while GW is producing the anti-counterfeiting marks, on the other hand, the needs of different stakeholders throughout the jewellery industry supply chain is being taken account. Hence, a variety of different types of diamond mark viewing IoT device are created mainly for jewellery production, QC inspection, retail store and customers viewing.
Diamond Surface Inspection Viewer (SI Viewer) is a viewing device designed for diamond manufacturers as well as diamond distributors. This device is delegated for quick examination of all the marks made on diamond tables (no matter they are protruded or etched marks), and defects or scratches on diamond table can be seen at a glance. This powerful device greatly facilitates the manufacturers’ work on diamond quality control.
Inspection Viewer is made with a powerful built-in precision lighting system which can improve auto- detection efficiency. It facilitates the jewellery quality inspectors to quickly check all the diamond marks on manufactured jewellery.
With a built-in multi-functional precision inspection device, this Product Viewer facilitates the inspection of diamond cutting, especially “eight symmetrical hearts and fireburst pattern”. Built-in wireless network, RFID and other functions are also available so a variety of personalized product information and logistics information to enhance customer experience in retail stores can be easily provided.
With a portable and lightweight design, the Mobile Viewer under simple operation allows customers to view the mark on diamond table anytime, anywhere.
Automatic diamond grading system
Traditional diamond colour and clarity grading mainly relies on the naked eyes and experience of diamond graders. GW successfully developed a new intelligent diamond colour and clarity grading system backed by hybrid AI which can effectively reduce human error, improve accuracy and repeatability of diamond color and clarity grading.
With a mega dataset exceeding 1,000,000 pieces of certified diamonds, our AI engine has learned the inherent lighting performance of diamonds and accurately grade diamond compatible to international standards, even more intuitive is that the AI engine could learn continuously. With our hybrid AI engine, the grading process would become more reliable, scientific and repeatable, avoiding inconsistent grading result by human judgement and nuisances created from various environmental inconsistency. The standardised diamond colour and clarity grading system greatly improves the grading accuracy and consistency of diamond pricing. Colour and clarity grading standards can be developed for data learning, thus simulating today's common diamond grading standards (e.g. GIA or National Standard GB/T 16554, etc).
