100% Silver in its pure form is too soft a metal to be strong and durable. It’s plausible to melt and deform with body temperature. To make the metal sturdy & durable, we combine 7.2% of copper alloy while in molten form. This increases the resistance of the silver metal, its life, and durability; while also enhancing the beauty and the original properties of silver. It can now be cast in any contour and design, and can set precious stones in it till eternity.
