I’m thinking of starting a gem certification lab. I need a full list of equipment I will need,the approximate cost for all the equipment and a website to buy them online all in one place.
Also I don’t need the equipment for testing diamonds.
I think that all depends on what you intend doing. If you mean to compete with the ‘Big Boys’ then the sky is the limit on what you need and what you have to pay out. If you intend to provide a service to the industry by verifying gems for jewelers and public then the basic tools would be all you need and if you have qualified as a Gemologist most if not all of those tools you would already have purchased in order to complete your course.
Have a read of this for all the basics - https://www.gemsociety.org/article/gemology-tools/
