Generations of Diamond Excellence


Certificates are documents that attest to the quality and authenticity of a natural diamond or Lab Created Diamond. The most accurate are issued by independent accredited gem labs that were not involved in the purchase or sale of the diamond.

It is important to buy certified diamonds as this protects you for appraisal and insurance purposes, should anything happen to your diamond, and allows you to more easily compare prices between diamonds.

At Spiro Jacob Diamonds, our diamonds are graded and certified by either the Gemological Institute of America (GIA) – one of the most respected gem labs in the world, or certificates from other respectable labs such as IGI and HRD (European Institutes).



Our Company has been in the business of assessing, buying and manufacturing natural diamonds all over the world for over 60 years.

Our Founder – Mr. Bernard Spiro z”l, was one of the first members of the Israel Diamond Exchange, since 1968, specializing in Rough Diamonds.

His Son – Mr. Jacob Spiro z”l followed in his footsteps and eventually assumed the role as the head of the company.
