A 14k gold necklace is valued at 58.5% of the 24 karat price of gold. Like to learn more Facts about Gold?

Cursive Writing Board
When it comes to markings on jewelry, the style of writing of the characters in the trademark, the sponsor's mark and date letters, provide important identification clues. A style of "joined up writing" called, cursive writing, often appears on markings on Antique jewelry and Costume jewelry. Confusion exists between print writing and cursive (which is also called script writing), so I decided to add a cursive handwriting guide to the jewelry resources page for you to cross reference initial marks on jewelry with script writing. One caveat, there a variety of different styles of cursive handwriting.
