White gold is an alloy (mixture) of yellow gold and other white metals such as silver and palladium. For example, 18ct yellow gold is made by mixing 75% gold (750 parts per thousand) with 25% (250 parts per thousand) other metals such as copper and zinc while 18ct white gold is made by mixing 75% gold with 25% other metals such as silver and palladium. So the amount of gold is the same but the alloy is different.

Our rhodium plating serves to give each piece a very expensive look that is almost identical to platinum or white gold, but at a fraction of the cost. Also, rhodium plating is very effective in preventing the effects of oxidation, or tarnishing.

Rhodium, a member of the platinum family, provides a hard, protective coating to white gold which brightens the color. While not used universally, it is an accepted practice in fine jewelry. This picture demonstrates the visual impact of Rhodium. The bottom ring is white gold without Rhodium, the top ring is white gold with a Rhodium coat. Some people find that the Rhodium plating degrades over time in daily wear, gradually revealing the color underneath.

Yes, all Ziamond white gold jewelry has a rhodium finish applied. This provides a lustrous Platinum like color and finish that deters scratches and emulates the color of luxurious Platinum. White gold in and of itself is not very white, it is actually yellow gold mixed with alloys to give a whiter look like Platinum, but it is still a not yellowish in tone, that is an additional reason for a rhodium finish. All fine diamond jewelry in white gold will have a rhodium finish.

Yes. We do white color plating such as Silver, Fake Rhodium or Rhodium plating as desired by you. We can also supply our products with bicolor plating. Our Silver plated bangles that match the White Gold color are very popular.

The plating thickness for decorative rhodium platings used by jewelry manufacturer can range from .05 microns to 1.5 microns. For most decorative applications, a thickness from .10 microns to .50 microns are utilized for maintaining long term "brightness". Industrial platings for specialized applications may utilize thicknesses up to 5.0 microns. However, rhodium finishes above 2.

Gold plating contacts should be used when your product needs a longer shelf life. Also if the switch will not be actuated for a long period of time after installation we recommend the use of gold plating.

The thickness for gold coatings and platings are often expressed in millionths of an inch, microinches, or microns. The table below will help provide a basic translation between these units of measurements. To translate all this into real world plating thicknesses and their relationship to U.S. Gov. F.T.C. regulations, the following table expressed in microns is provided as a point of reference.

No, as a rule the electroplating process does not hide surface imperfections. In fact, due to the diffusive reflection of incidental light rays, pre-existing cosmetic imperfections are even more noticeable on a brightly plated surface! For best results the item should be polished to the desired level of brightness prior to rhodium plating.

Yes... Rhodium is a thin coating placed on silver, white gold, and platinum jewelry to give it a high polish finish. Dust and contaminants in the environment interact with body oils, lotions, etc to form an abrasive mixture that begins to wear away at rhodium and plated jewelry. Removing these contaminants can significantly extend rhodium life.

Gold plating on sterling is a process where we plate at least one micron (40mils) of gold on to the surface of sterling silver. Some people call it gold overlay on sterling, gold bond on sterling etc. Two tone gold & silver plating is similar to gold plating, but it requires two steps plating. The first is gold plated and certain areas are masked or covered and then the jewelry is silver plated again to give it the ultimate two color effect.

Stainless Steel lasts longest, followed by Rhodium and then Gold. Gold tends to tarnish after time. Also, Gold is used to tonify (+), while Stainless Steel is neutral.

Yes, "double plating" can be done. But, if you plan to make an order with such process, please confirm with our account executive in advanced. info@scorpion.com.hk it is inferred by their names, "Cloisonne stamped with Hard Enamel" & "Brass Photo-etching with Soft Enamel" do not refer to the same manufacturing processes. Cloisonne stamped with Hard Enamel refers to stamping. The material which is being stamped is Copper. On the other hand, Photo-etching is done only with Brass.

Simply the best looking, most durable gold plating process available. Unlike other's Titanium Gold kits, which are coated with epoxy and may appear grainy as the epoxy wears off, WoodWrite, Ltd. Titanium Gold is a true 24k gold finish over a pure Titanium base which actually shines up as it wears. WoodWrite, Ltd. has found a better method of plating with Titanium which reduces our cost. We also plate with a Titanium alloy which is "EXACTLY" the color of the 24k gold top coat.

Yes, this is called selective plating. Designated areas of the metal object can be plated with yellow, rose and green gold deposits. It also is used for selectively restoring gold plating on metal objects when traditional plating is not suitable due to the fragility of the piece.

No – we coat these metals with a special protectant to ensure they will never tarnish when properly cared for.

Pure gold is too soft for use in jewelry, so it is usually mixed with other metals or "alloyed" to make it harder. White gold is produced from the mixing of gold, copper, palladium, and zinc. Various shades of yellow gold can be created from the mixing of gold, silver, copper, and small amounts of zinc.

White gold is alloyed with nickel. White gold is substantially harder than yellow gold. We offer only 14K white gold. 18 K white has been a problem for us. Some people are allelic to nickel, but if you are you probably already know it. Because silver has been historically used for Celtic jewelry white gold is frequently chosen to give a historical look but with the durability of the much harder metal.

Rhodium is a member of the platinum metals group; the other members include platinum, palladium, ruthenium, iridium, and osmium.
