    Purity

    Renowned for its gleaming luster and denseness, gold is known as the softest and most pliable natural metal. In its purest form, gold is bright yellow in color, but is often mixed with other metals, such as silver and copper, to form a more durable alloy that's more resistant to everyday wear and tear. Additionally, these alloys help color gold and produce shades of white, yellow, and rose. At Brilliance, we specialize in high-quality 14 karat and 18 karat pieces, the standard for fine gold jewelry.

     
    Gold Purity
    There are various grades of gold purity, determined by the ratio of their alloy composition and rated by a karat system. Typical karat purities range from 10 karats to 24 karats (pure gold), with a wide variation of usage from country to country. In the United States, the most popular composition is 14 karat gold.
     
    Below are some of the most common gold densities, along with the characteristics and pure gold content of each:
     
    24 Karat Gold
    In its purest form, the metal is comprised of 100% gold with virtually no alloy metals. Pure gold is extremely soft and pliable, which is why it's often mixed with other metals, such as copper and silver, to forge jewelry.
     
    22 Karat Gold
    This level of gold is 91.7% pure which is still too soft to make jewelry and not as durable as 18K or 14K.
     
    18 Karat Gold
    This alloy consists of 75% gold and 25% alloy metals. 18 karat gold has been found to be the perfect balance between gold purity and strength. Brilliance offers a variety of exquisite 18 karat gold jewelry.
     
    14 Karat Gold
    14 karat gold is 58.3% pure gold; the remainder is comprised of alloy metals. Any gold purity less than 14 karat gold is not recommended for high quality jewelry.
     
    10 Karat Gold
    This tier of the metal consists of 41.7% gold. This is the minimum purity that can still be considered gold in the United States and is not used for high quality jewelry.

    Platinium Education

    Often heralded as just as beautiful as the gems it displays, platinum boasts a silvery-white luster that imparts unmistakable elegance and blends well with a variety of metals and stones. Four times stronger than gold, platinum is renowned for its hard-wearing properties, resistance to damage and wear, and its substantial heft.
     
    At Brilliance, we're proud to offer a wide assortment of platinum settings for our finest jewelry pieces. All of our platinum consists of at least 95% pure platinum, with a maximum of 5% alloy metals. Nearly all of our solitaire and engagement rings have platinum prongs to keep diamonds securely in place.
     
    Platinum Purity
    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.
    950 Platinum
    Pieces marked with a 950 purity are a blend of 95% platinum and 5% alloy metals (usually ruthenium , copper, cobalt, iridium, rhodium, or palladium).
     
    900 Platinum
    Pieces marked with a 900 purity consist of 90% platinum and 10% alloy metals (usually ruthenium or iridium).
