ORRO's proprietary Platinum Vermeil material is created using Molecular deposition Vacuum Plating TechnologyTM where a sterling silver base is plated with a metal from the platinum family. Using sophisticated machinery, layer upon layer of platinum is deposited onto the solid sterling silver base. This process is repeated twelve times.

Our Platinum Vermeil metal is comparable to pure platinum in appearance and craftsmanship. Because it's primary base composition of sterling silver, our Platinum Vermeil is considerably more affordable than pure platinum. The very definition of value for money.

Sterling silver provides a proper inert foundation for platinum, which reacts irreversibly with cheaper base metals. Worn with caution, the platinum plating can retain its perfect appearance indefinitely. If however, the platinum plating is damaged by scratches, the underlying lustre of pure sterling silver will continue to provide an equally lustrous shine to complement your exquisite ORRO diamond simulant Gemstone.
18K Rose Gold Vermeil (925)
18K Rose Gold Vermeil had a base material consisting of 92.5% pure silver. The material is micron plated with pure 18K Rose Gold giving it the beautiful pink color. The color of the alloy is exactly the same as that of solid 18K Rose Gold.
18K Yellow Gold Vermeil (925)
18K Yellow Gold Vermeil had a base material consisting of 92.5% pure silver. The material is micron plated with pure 18K Yellow Gold giving it the beautiful natural color of gold. The color of the alloy is exactly the same as that of solid 18K Yellow Gold.
White Gold is an alloy of gold mixed with other white metals such as silver and palladium. The result is a grey colored gold. In order to give the gold a 'white' look, it is plated with a platinum family metal called Rhodium. Rhodium is a beautiful lustrous material that is very hard and costs twice as much as platinum and four times as much as gold. If you wear your solid white gold ring on a daily basis, it will be good to re-rhodium plate it approximately every 12 to 18 months. Most local jewelers are able to rhodium plate your white gold jewelry at a reasonable price.

Most ORRO jewelry is available in Solid 18K White Gold.
Yellow Gold is an alloy of gold and other yellow metals to make it strong enough for crafting into jewelry and hard enough to resist scratching. Our yellow gold mountings are polished by hand and like all gold jewelry, they need to be polished every 12 to 18 months, depending on how often it is worn.

Most ORRO jewelry is available in Solid 18K Yellow Gold.
Rose gold is also known as crown gold, which is 22 karat. For 18 karat rose gold, typically about 4% silver is added to 75% gold and 21% copper to give a rose color. At ORRO, our rose gold is elegant and has a unique old world charm to it. It captures nostalgia and exudes elegance. To keep with this charmed luster, we take pride in the combination of our rose gold alloy and are all designed and crafted by skilled craftsman. Rose gold is perfect for dazzling gemstones and its tinge of colors has a nice character to it.

Most ORRO jewelry is available in Solid 18K Rose Gold.
Pure solid platinum (PT950) is of high quality and is silver-white in color. It is lustrous, ductile, and malleable. Platinum is more ductile than gold, silver and copper. It is the most ductile of pure metals. Unlike other metals, due to its chemical property it does not oxidize at any temperature. Platinum is insoluble in acids and thus it is a very chemically resistant metal. Platinum’s resistance to wear and tarnish is well suited for making fine jewelry; the very reason why we have a pure platinum collection to compliment our gemstones. Pure platinum is harder than pure iron. The metal has an excellent resistance to corrosion and high temperature.

In terms of aesthetics, platinum has all the subtleties of a truly refined beauty and it provides a perfect setting to showcase your stones.
