8th Dimension Gems

Since 2003, Primagem has been serving the gem & jewelry trade with exceptional natural gems, excellent photography, open sharing of gemological knowledge with an emphasis on full disclosure of enhancements, and corporate social responsibility supporting New Blood Academy for students and orphans from Burma (Myanmar). 

Due to frequent confusion with Prima Gems, Bangkok and Prima Gems New York, we are rebranding as 8th Dimension Gems by Jeffery Bergman as of January 1, 2020 in celebration of 50 years in the gem trade. 

The 7 Dimensions of Gemstones are: Identification, Color, Clarity, Cut, Carat weight, Enhancements, and Origin. 

The 8th Dimension is Integrity; credible lab reports, ethical sourcing, and corporate social responsibility.
