FIRST TIME STUDENTS:

The package for Beginner course is 80.000 THB, and then again 80.000 THB for the Intermediary course.
It seems a little bit expensive to some students coming from gemological studies like AIGS or GIA in Bangkok for instance, until they realize that at the end of this 3 month program (beginner + intermediate) they actually become gemstone cutters.

The major difference with gemology courses, is that at by taking the GCL Courses you really learn a new profession and that your knowledge is immediately convertible into income.
If you own cutting a gemstone cutting factory, you will be able to teach and control your staff, and improve your factory's productivity and reduce material losses.
If you need a job and you already have some education background, you can be managing a modern cutting workshop.
As a former student you will have our technical support after you finish your program in order to help you with your first experiences.

As our instructor, M. Carlos Gomez Leal likes to say: "Do you find knowledge expensive? Try without it."

ABOUT GEMSTONES CUTTING LESSONS PRICES:

Many students graduated from GIA, HRD, AIGS finally find themselves out there on the market with a nice trusted diploma but actually without any clue about the reality of the gems business. It is quite natural because these schools teach about gemstones identification, gemstones treatments identification, theoretical things about light and color, crystals and their properties, as well as practical examination of a stone, but nothing about making profit out of that knowledge.

Why is that? Because it is not their vocation to do that, just like an MBA teaches about how to run a business but do not tell which business to create and how to be successful with this particular business.
To become a gems dealer takes years of practice on the market (on Your market should we say since the gem business is not practiced the same way in Bangkok, Dar Es Salam or Paris).

In the lapidary area things are less complicated and the income is almost certain since you transform row material into finished product.
There is only the cutter, the stones variety and its properties. Then it is up to the cutter to buy good material and calculate how much he can get out of it.

At the Gem Cutting Lab students learn how to make a living with their hands and the knowledge they will acquire here is not available everywhere. We teach cutting techniques that have been taught through generations of Brazilian cutters. Actually some of them are not very happy to see that knowledge being transmitted outside the circle of Brazilian specialists, because it is their specificity to carry this knowledge around the world.
Therefore this knowledge is valuable, and just like gemstones it is rare, it is durable and it brings beauty at the tip of your fingers.

The second thing justifying our prices for the gems cutting courses is more material an easier to understand.
We supply students with rough gemstones material and gemstones preforms to cut, facet and polish all along your courses (mostly quartz family for clean stones). This rough material has a cost, especially the clean material that we provide for you to learn how to slice carefully, eliminate impurities, repair broken edges, re-cut, transform octagon into cushion, etc.

* International Student coming straight to us and willing to take both beginners and intermediate courses can ask for a discount. We take in consideration the fact that they will have some expenses to come and stay in Bangkok for the duration of their studies at the Gems Cutting Lab, and we really want to encourage them to come and experience a great new area in the world of crystals.

ABOUT GEMSTONES CUTTING LESSONS SCHEDULES:

Students can start the courses almost anytime they want depending on the immediate availability in each level. We do not plan to accept more than 8 to 10 students per level. Therefore the courses are very personal and each student will have an opportunity to insist on the areas that are difficult for him until he gets it right.
We are quite flexible on the way they want to organize their sessions until they complete the program. Nevertheless each block should be taken in a continuous stream allowing the student to benefit from it, and allowing us to organize time tables for the weeks to come. Students who are jumping lessons or delaying an entire block will lose priority on the next courses. Priority then will go to new students willing to follow the program continuously.

Accelarated Courses:

We also provide accelerated courses in order for some students to finish both beginners and intermediate programs in 2 months instead of 3 months. International students, and cutters sent by cutting factories often need accelerated programs.

Warning: 1 hour and a half of cutting lesson everyday require a lot of concentration. We do not recommend pushing yourself to make 3 hours per day systematically all along the week. In the end you would not benefit from your lessons and you may not pass the test opening the door to the intermediate courses. This would result into the necessity of paying extra lessons (3.000THB per session) outside the frame of your package before you can be integrated with other intermediate level students.

We recommend one single lesson per day and maybe 2 lessons in a row 2 days of the week in order to bring down the duration of the entire program to 4 weeks instead of 6 weeks. More than this is too much already for a student and would lead to loss of valuable material, loss of time and accidents due to a lack of concentration.

Longer concentration skills will come with practice when the basic gestures become natural to the cutter.
