Your Choices
Rings can be manufactured out of 9ct, 14ct, 18ct gold in white, yellow or two-tone combinations. Alternatively, they can be made out of platinum. All available alloys are displayed in the options window. Where applicable, the price of the setting alloy includes all side and extra diamonds or gemstones - as outlined in the items description, next to the image.
Images
With the exception of two-tone rings all images are pictured in white gold. So, if you select white gold or platinum, the item will look exactly as the image. If you select yellow gold, the item will be of the same design but yellow in colour (made from yellow gold). Please note that displayed computer colours may vary from actual colours of the finished product.
Yellow Gold
In South African jewellery you'll mostly find 18ct and 9ct yellow gold. 18ct gold contains more precious metal than 9ct gold. It is composed of 75% gold, which is alloyed with other metals to make it strong enough to withstand every-day wear. Because 9ct gold is composed of only 37.5% gold, and 62.5% other metals that give it strength, its gold colour is not as rich as 18ct gold. Because of this composition 9ct gold is also cheaper than 18ct gold. 9ct gold is commonly in demand where durability and budget considerations are most important.
White Gold
Because 18ct white gold is 75% gold, and 9ct white gold is 37.5% gold, jewelry made from these metals has a slight yellow color. For the silver-like appearance of the 18ct white gold a palladium metal is added to its alloy mixture. To further enhance the whiteness, especially on lower carat alloys, white gold is plated with rhodium, a shiny white metal which is extremely hard. Depending on the amount of wear to a piece of jewelry, over time this rhodium plating may wear off, revealing the original metal color. Re-plating is a simple process that can be done to restore your jewelry's whiteness if needed.
Platinum
The most appealing characteristic of platinum is its durability. Each time other metals are scratched or polished, a tiny bit of metal is lost. 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 easily chip or splinter. The majority of our platinum jewellery is 95% pure platinum combined with 5% iridium, palladium, ruthenium or other alloys. For guaranteed quality in platinum, look for the marks 950, 950 Plat or Plat.
