Goyam Diamond Institute

Goyam Diamond Institute was established in 2000 as training institute for diamond and jewellery designing. It is located in diamond city Surat, Gujarat which has a strong significance in International Diamond trading as 92% of the world's diamonds are cut and polished in Surat. Goyam Diamond institute is well known for its complete practical training of rough diamond sorting- planning-marking, diamond cutting & polishing, polished diamond grading according to domestic market, grading system according to international standards, valuation system for loose and studded diamonds, diamond valuation according to rapaport, color grading of fancy color diamonds, jewellery designing manual & computer aided 2D & 3D (CAD 2D/ 3D (Rhino)), gemology, metallurgy (essential), jewellery manufacturing hand-made & casting, e-commerce, export management etc. With more than a decade of existence Goyam is known for its quality education in Diamond and Jewellery designing as we developed a unique training method for diamond and jewellery designing  education.

To make student a 'COMPLETE BUSINESSMAN' is aim of Goyam. And in this endeavor at Goyam we conduct different courses related to all subjects mentioned above. “Goyam” has established International Quality Management System and acquired ISO 9001-2008 certificate.

At the time of establishment, we started to teach, things that others do but as time passed we realized that our students are having only technical knowledge. That was not sufficient to perform efficiently in the field.

As we realized, only technical designing was not sufficient. People who desire to do business or who had requirement of cost based jewellery designing, knowledge we were giving was not sufficient for that. After months of exercise, calculation and teamwork we designed a method to estimate the cost of jewellery at the time of designing.

Now our students can estimate how much quantity of material will be used in the jewellery they have designed. They can design jewellery on the base of particular budget or amount.

In the diamond education we realized that to know grading system only is not sufficient to do business of diamond or jewellery. Students who had acquired excellence in grading were feeling helpless as they cannot do business in the absence of the knowledge of valuation. Continuous two year's exercise of our team, they have designed a unique valuation system of loose diamonds. Now we were ready to give the knowledge of valuation system of loose diamonds. But that was not an end.

Valuating loose diamond was enough to trade loose diamonds, but not for jewellery. Different calculations and exercise resulted in jewellery valuation system.

Our students can calculate weight of studded diamonds with the accuracy tolerance of +/-2%. They can grade studded diamonds with the accuracy of one grade in colour and clarity. They can measure proportion of studded diamonds with the accuracy of loose diamonds.

 In rough diamond our student can estimate weight of polished diamond, clarity and color.

“One to one training & one student one equipment” method.

As we realized that practical knowledge is more important than theoretical knowledge. We have reduced theory sessions from all the courses. At “Goyam” all training like diamond cutting, grading and valuation is given on the actual materials and natural diamond only. We follow one student one equipment system.

The most important thing we have applied in “Goyam” is individual training at our campus. We do not follow batch system. Because of that thing, an individual can assign his or her on learning speed as per his/her capability. Because of this system a student can achieve excellence in all the modules he/she learn. This system has given us 100% result ratio.

We have acquired 100% employment. We conduct free career consultancy over here. In this service we guide our student about how to achieve the goals. We also give placement assurance to our students of career courses. If they desire to do business, we also guide them at our level best. This service has brought us 100% employment.

A vast range of different courses cover all the aspects of diamond, gems & jewellery field. We offer courses for rough diamond sorting- planning-marking, diamond cutting & polishing, polished diamond grading according to domestic market, grading system according to international standards, valuation system for loose and studded diamonds, diamond valuation according to rapaport, color grading of fancy color diamonds, jewellery designing manual & computer aided 2D & 3D (CAD 2D/ 3D (Rhinoceros 4.0), Design estimation, cost based and cultural jewellery designing, gemology, metallurgy (essential), jewellery manufacturing handmade & casting, e-commerce, export management etc.

We are enjoying the never ending journey of inventions and innovations with your support & love.
