Can anyone...
....differentiate silver, rhodium plated white gold and platinum, without
side-by-side comparisson and using just eyes? If so, how? Thnx! |

Silver, if not rhodium plated, is MUCH whiter in color than either of the others. If rhodium plated, then the lower density can sometimes tell you its not white gold, and other times construction or surface finish details will also tell you. Rhodium on silver has underplated layers of first copper, and then nickel, and the result is that the plated nature of the surface is more obvious. But it can be subtle. Still, it's a good deal lighter than white gold, and usually you can tell. Nickle white golds are also harder and stiffer, so the feel in the hand, and wear patterns will differ from silver, and the types of things that are made will also often differ, so the nature of the item itself can give you a good clue. And while not all silver will have a readable stamp once it's worn a while, most white gold will still have an at least partially readable quality stamp, which usually can be trusted to at least give you a very strong suspicion that its gold. Platinum, is generally easy. The color is much darker than silver or white gold, without any yellowish or brownish (palladium white golds can be brownish tones) tone. The heft is MUCH heavier, enough to be obvious even to many beginners. And the density and toughness of platinum combined with it's relative softness means the wear and scratches one sees on platinum are quite unlike how the surface of gold or silver appears after some wear and tear. Platinum is seldom a problem to identify, though platinum that's been repaired with white gold solders or the like, can be easier to miss if its done well and then rhodiumed to cover the color of the repair. In general, telling silver from white gold or either of them from platinum, is not that hard with most pieces of decent enough size and weight so you can get some idea of heft. Where you run into trouble is things like telling different karats of white gold, or in some cases, the better palladium white golds from nickel white golds. Those determinations can get tricky enough to require actual testing. Peter |

You could carry small samples with you, if required, to do comparisons.
At least until you become familiar with the look. Fine silver, sterling silver, rhodium plated, 'german'(nickel) silver, platinum. Presidium (IIRC , others too) have pocket sized testers for metals - I doubt they are 100% trustworthy but perhpas useful.

Silver is lightweight and a little bit yellowish in colour. 2. White gold, rhodiumplated is medium weigth ans the colour of rhodium is perfekt white and "cold colour", means going to blue. 3. Platiunum is the heaviest of this three and the colour is clean white if alloyed with iridium or copper (old style alloy) or greyish if alloyed with cobalt. All these differences are very small and there is much experience mandatory to identify without tests. best whishes, Heinrich Butschal -- www.schmuck-boerse.com www.meister-atelier.de www.schmuckfabrik.de www.royal-magazin.de |
