The platinum jewelry at Jacob Ruth & Co. is made of fine quality jewelry grade platinum. Its cool white sheen makes platinum our most popular metal of choice for settings, as it accentuates the sparkle and brilliance of a diamond. The most appealing characteristic of platinum is its durability. Each time other metals are scratched or polished, a tiny bit of metal is lost. In fact eventually, prongs of white gold and yellow gold may wear down enough that you need to have them reinforced with more metal for safety.

But not with platinum. A scratch in platinum may leave a mark on the metal, but this metal is so strong that it will not readily chip or splinter. For that reason, we set all loose diamonds in safe, secure, platinum prongs.

While it is the strongest of jewelry metals, it can scratch and develop a patina of wear. Many people prefer this look, unique to platinum. But if you like the shine, a jeweler can polish your jewelry to bring back the original reflective finish. In the mean time, buffing with a soft cloth can give your jewelry renewed luster.

The majority of our platinum jewelry is 95 percent pure platinum combined with 5 percent iridium, palladium, ruthenium or other alloys. For guaranteed quality in platinum, look for the marks 950 Plat or Plat.

Soaking platinum in a mild solution of soap and warm water and gently scrubbing it with a soft-bristled brush is usually all that is required to maintain the metal's luster.
