Gents, thank you for your answers.
When I say diamond is a stone, I mean gemstone (native crystalline carbon). Pardon me for this inaccuracy.
In Russian books about rigging, Diamond Knot (Knob, Button) has a name originating from the gemstone. That had been translated for so many years ago.
Picture #416 from ABOK, p.67 shows a rhombus from a rope. It is obvious. But what about #693 (ABOK, p. 121)? What is it? Is it a gemstone or rhombus?
Thank you.
