Considered among the most pure and precious metals used in modern-day jewelry making, platinum has become synonymous with luxury and longevity. Because of its hardness and durability, pure platinum is often mixed with other metals to make it more malleable. The most common alloy metals paired with platinum are copper, palladium, rhodium, iridium, and titanium.
Although some alloys may be billed as platinum by jewelry sellers, there are stringent requirements for what constitutes a 'pure' platinum piece. Only metals marked with a 950 or 900 purity designation are considered high-grade platinum. Alloys containing a lower ratio are often used to make jewelry, but these pieces don't impart the same high standards of quality, longevity, or beauty. At Brilliance, we use only the purest platinum alloys to craft our fine jewelry.
Pieces marked with a 950 purity are a blend of 95% platinum and 5% alloy metals (usually ruthenium , copper, cobalt, iridium, rhodium, or palladium).
Pieces marked with a 900 purity consist of 90% platinum and 10% alloy metals (usually ruthenium or iridium).
