French modernist cufflinks

I have tried to find out about these French cufflinks , I can’t find anything about the manufacturer FAST ?? Or about the metal and wondering what these baguette cut stones could be , grateful for any help
Thank you

 

The stones are rhinestones. I don't recognize the maker - Brevete SGDG is likely a gold-filled mark. Beyond that I'll wait for the European contingent.

 

Breveté Sans Garantie Du Gouvernement
https://en.wikipedia.org/wiki/Breveté_SGDG
"Breveté SGDG was a French type of patent that ceased to exist in 1968. The name was a common abbreviation for "Breveté Sans Garantie Du Gouvernement“ (patent without government guarantees)."

 

Here is a different style pair (no stones) for sale on Ebay, same marks:

And on Etsy
https://www.etsy.com/listing/4365263549
"Vintage French Gold Tone Roman Coin Cufflinks by FAST"

And if you google "boutons de manchette" "fast", you'll find a few more from French sellers.

But still no additional info on FAST

 

Some cufflinks that have the FAST mark, are signed with Reyt.
It didn't help me finding any more info on who that Reyt is, but P.I. Debora might be able to find something more with that intel.

 

looks like Hebrew when rotated right........

 

AI (for what it's worth):

"Reyt (France) is a vintage jewelry brand known for its 1970s Brutalist, Modernist-style pieces, often crafted in sterling silver. These, often handmade, items typically feature raw, free-form, hammered, or textured designs and are frequently signed "Reyt" or "Reyt France," including items like large pendants and crosses.

Key details about Reyt jewelry include:

• Style: Known for creating Brutalist or free-form jewelry.
• Signature: Pieces are typically marked "Reyt" or "Reyt France".
• Materials: Frequently crafted from .925 sterling silver, sometimes featuring gold plating or plating."

Could FAST be the name of the patented post design?

 

wouldn't it be on the post itself, then ?

 

Probably...

 

FAST might be the name of the design line. I've never seen the Brevetè mark before.

 

The Breveté SGDG mark was used until 1968.
And fwiw, this specialised seller thinks his FAST cufflinks, different model, are 1940s:

The Etsy seller says his cufflinks are 1970s

 

Wendlekins' cufflinks aren't marked Reyt. The cufflinks marked both Reyt and FAST could be some sort of collaboration.

 

Some sellers....

 

Pity there isn't more information to be found on the internet but the FAST designs are quite interesting.
