Can you please read what it says on the button on the last picture in the middle of the Rosette. On the There are 3 rosettes on a Masons apron with symbolism of "Fidelity to the Craft, Secrecy as regards our sacred Secrets, and Silence as to the proceedings of the Lodge, which should never be disclosed to the profane." However, this is a Star of David Symbol....which isn't known in Masonry. The wording could help alot on this.
The sets of silver and gold tassels are for a Masonic Apron. These are called "secure tassels".
There are Master Mason Gold Tassels
