I have a metal jeweller's loupe with a smashed lens, and I would like
to find an exact replacement, or at least contact information for the
manufacturer. I have been unable to locate any information about the
company (Rubin & Sons, I believe) or where I can obtain their
products. Maybe you'll have more luck? 

The outside of the loupe reads "23MM - 6X / TRIPLET / R.RUBIN / ANTWERP"

Thanks for your help!

Hi somatose,

The following is the result of my research for Rubin & Son website and products: 

"Over the past fifty years, Rubin & Son has grown into the leading
supplier most trusted by the diamond and jewelry industry for their
supplies, tools and instruments. Over this period, our company which
was originally founded in Antwerp (Belgium) by Robert Rubin, has not
stopped expanding, by continually seeking new markets and innovative
high standard products. Today, Rubin & Son is considered as a global
player in its field, with companies and dealerships across Europe and
the Middle East as well as the US and Asia..."

Clicking on Products in the left-hand menu of the Rubin & Son website
will take you to a list of all products available by Rubin & Son. In
the list of products you will find Loupes. Clicking on that will lead
you to their manufactured loupes.

"Rubin triplet loupes- 
These Rubin triplets provide the best value among regular loupes in
the market today. The optics have been changed, but the product has
