How To Become a Diamond Tester

There are some occupations that are simply a bit more exciting and glamorous than others. One of these is diamond testing. Working with a stone as precious as the diamond, the job does carry with it an air of prestige by sheer default. Working day in and day out as a gem tester, however, is not as easy as it may seem. You will need to be able to act as a color tester and a ram tester for the diamonds as well, and should be able to determine the quality of diamond – and there are various types of diamonds that the uninitiated may take for granted. Here the ways for you to become a diamond tester that can determine a high quality diamond from simple diamond moissanite.

  1. Formal training. Everything from carats, color quality, cut, brilliance, and make should be known by a good diamond tester. With various cuts of diamonds out there – ranging from the baguette to the Marquise cut to the pillow cut – learning how to distinguish one from the other can be very difficult. And while cuts are one of the simplest facets of learning how to be a diamond tester, there are things that even the lay diamond fan cannot easily recognize, such as the providence of the stone, tools to cut the stone with accuracy, and how to conduct comparison between diamonds. Self help is usually not enough for you to become a good diamond tester, and you will need to undergo formal training. This is especially important since you need an institution that will allow you to work up close and personal with real diamonds – something that does not fit the category of do-it-yourself learning. These formal training courses can be provided by jewelry makers and some vocational schools.
  2. Apprenticeship. After a few weeks or months of training, however, you will need to undertake an apprenticeship period with a local diamond dealer or a jeweler. This will allow you to work not only with the few stones that were shown you in the training courses that you have attended. In the apprenticeship stage, you will be able to work on identifying a large variety of diamonds and other precious stones which the jewelers create and sell. You will work with the master diamond tester of the particular jewelry shop that you have chosen, and he will in turn further refine your skills in identifying and classifying not just the quality of diamonds but other stones and metals as well – you can even be a bit of a gold tester along the way. The master diamond tester will even give your performance constructive criticism and reviews.
  3. Getting into the industry. Once you have been deemed learned and trained enough, you can either become a senior diamond tester in the jeweler company where you took your apprenticeship, or you can search for a new group that is in need. Keep in mind, however, that the market for diamond testers is pretty competitive – there are only a very limited number of slots available. Unless you work on getting the best connections in the industry, you might end up testing low quality diamonds in small jewelry business that cannot actually acquire larger and more expensive rocks.

It will take time to become a diamond tester. Like other professions, diamond testing requires skills that cannot be learned overnight. If you succeed, however, you will have a steady career that deals with nothing less than some of the most beautiful rocks on the planet.
