A solid back signet ring such as this one made from 14kt yellow gold is a great piece of heraldic jewelry that allows you to show off yourself and your family with an engraving of your initials. Up to three initials can be engraved with computer, laser, or hand engraving in Roman or Script font in a face that measures 11.4 mm x 10.5 mm. This piece having a solid back means that more gold has been used in its manufacture and allows it to weigh about 6.6 grams.
