Hi Shaun thank you for sending in the following hallmark question:
"What does the engraving of RF on a man diamond ring stand for? I found the ring so I have no known history. It has 4 square diamonds and 6 small diamonds all going in a diagonal pattern. Any help you have would be greatly appreciated. Thank You Shaun"
Shaun, there are a few RF initial maker's marks. Is there a punch mark behind the letters? Is it a rectangle?
