          2. ABOUT MYSELF

    For as long as I can remember I had the destiny to be an electronics engineer. I have the skills and the form of engineering thinking. At the time to enrol in a university, I enrolled in engineering studies and even completed my degree studies at Tel Aviv University. (1988)

    As a student, I worked for Scitex, a pioneer company in the field of pre-printing. I worked in a lab that developed scanning and image processing systems, which is what Photoshop does today.


    The beauty excited me.

    After graduation, while looking for a job as an engineer I was not enthusiastic about the job offers I received. Something was missing in them; at that time, I still did not know what.

    A friend offered me a job in the diamond industry.I have decided to give it a try. In order to get to know and specialize, I cut and polished diamonds for about a year time. I loved the process that the diamond goes from a shapeless rough stone to a sleek and shiny diamond.

    Two years latyer (1991) I combined the diamond's knowledge  with engineering  and collaborate with a company that developed automatic machines for cutting and polishing diamonds. I was enthralled by the algorithm that runs the polishing steps from a shapeless rough stone to a perfect cut diamond.

    In 1994 I first purchased mechanical design software, I was fascinated by the precise design technology, using a PC and CNC milling machine for high end jewellery . It was a technology in its infancy and quite primitive compared to what it has today. But at the time it was WOW. Here I first realized that this is the exact place I want to be.

    The combination of innovative technology, creativity, and beauty.

    This is my life experience.

    Following this, I founded Unison Gemstones Ltd. I built a factory that had state-of-the-art technologies, diamond polishers, diamonds setters, goldsmiths, and CNC operators from the best that can be found.

    Over the years we performed complicated and complex jewel pieces, we did not hesitate to take risks and learned while planning and executing. (as shown above).Thankfully there were no failures.

    We have always been careful to adopt new technologies that have appeared in the market such as 3D printers that have replaced CNC machines. Laser  machine, updated softwares and photorealistic imaging.

    All these years we worked B2B, mainly with the top Swiss brand companies of watches and jewellery.

    Following the coronavirus and the freedom that was taken from us, we decided it was time to enter eCommerce and change our strategy to B2C.

    Still the same enthusiastic team of great professionals who want to produce a high-quality and beautiful product.

    About ten years ago I returned to the University to study for a master's degree in the Faculty of Art.

    Beyond the job I love, I do outdoor sports. Mountain biking,  mainly singles , and kite surfing. In addition, I shoot videos using a Mavic drone. I like to realize how small we are in relation to nature.

    It inspires me a bit of modesty.
