Pure Gold heart pendants

Because of the softness of untainted (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point hue and other properties. Alloys with smaller caratage, normally 22k, 18k, 14k or 10k, comprise higher percentages of copper, or other groundwork metals or shiny or palladium in the alloy. Copper is the most routinely utilised base steel, yielding a redder hue. Eighteen carat gold encompassing 25% copper is found in antique and Russian jewelry and has a distinct, though not superior, copper cast, conceiving increased gold. Fourteen carat gold-copper alloy is almost identical in color to certain bronze alloys.
