Is That Ring Platinum or White Gold? How to Tell in 30 Seconds

Platinum Buyers ยท Houston, TX Platinum Buyer in Houston: Is That Ring Platinum or White Gold? How to Tell in 30 Seconds They look identical in a jewelry box. One contains roughly 95% precious metal, the other about 58%. Here is how to spot the difference before you sell. The most common conversation a platinum buyer in Houston has starts with somebody sliding a plain white band across the counter and saying “I think this is white gold.” Roughly a third of the time, it isn’t. Platinum and white gold are nearly impossible to tell apart by eye, which is exactly why platinum gets undersold, traded in, or left in a drawer for decades. The good news is that the difference is easy to confirm yourself with a magnifying glass and your own two hands, and it matters a great deal, because a platinum ring typically contains around 95% pure precious metal while a 14k white gold ring contains about 58%. Quick Answer Platinum is stamped PLAT, PT950, PT900, or IRIDPLAT, feels noticeably heavier than a white gold ring of the same size, and stays white forever. White gold is stamped 14k, 18k, 585, or 750, weighs less, and is rhodium plated, so it slowly turns warm and yellowish at the back of the band as the plating wears. Platinum is usually 90% to 95% pure, which is why it is bought and paid for by weight and purity like any other precious metal. The 30-Second Test Four Ways to Tell Platinum From White Gold Without a Jeweler 1. Read the stamp. Look inside the band with a magnifying glass. Platinum says so: PLAT, PT, PT950, 950, PT900, or on older American rings, IRIDPLAT or 10% IRID PLAT. White gold uses karat marks instead: 14k, 585, 18k, 750. 2. Feel the weight. This is the test people trust once they try it. Platinum is one of the densest metals used in jewelry, considerably denser than gold alloys. Put a platinum band in one hand and a white gold band in the other and the platinum feels obviously, almost surprisingly heavy for its size. 3. Look at the back of the band. White gold is plated with rhodium to make it bright white. That plating wears off with daily contact, so a worn white gold ring shows a faint warm, yellowish or grey cast underneath, usually first on the underside. Platinum has no plating to lose. 4. Check the surface texture. Old platinum does not lose metal when it scratches, it displaces it, developing a soft satin finish jewelers call a patina. Old white gold looks dull and slightly yellow instead. Reference Chart What Every Platinum Stamp Means Platinum purity is written in parts per thousand, the same system used for silver. Anything at 850 or above is sold and taxed as platinum in the United States. Stamp Composition Where You See It PT999 / 999 PLAT 99.9% platinum Bullion bars and coins PLAT / PT950 / 950 95% platinum The US jewelry standard, most rings PT900 / 900 PLAT 90% platinum Common in Japanese and older pieces PT850 / 850 85% platinum Chains and lighter-weight jewelry IRIDPLAT / 10% IRID PLAT 90% platinum, 10% iridium American rings from roughly 1900 to 1950 PD500 / PD950 Palladium, not platinum 2000s wedding bands, still valuable 14k / 585 / 18k / 750 White gold Rhodium plated gold alloy WG, “White Gold” Gold alloy Not platinum, priced as gold If you find an IRIDPLAT stamp, pay attention. That mark dates a piece to the first half of the twentieth century, the height of the Art Deco era, when platinum was the metal of choice for fine engagement rings. Those pieces sometimes carry design and period value on top of their metal weight, so they deserve a proper look rather than a scrap-only quote. “A platinum ring does not wear away, it wears in. Every scratch it has collected is still there in the metal, and it all still weighs on the scale.” Why Platinum Is Different Rarer Than Gold, and Priced by a Market Most People Never See Annual global platinum production is a small fraction of annual gold production, and the supply is concentrated in a handful of countries, with South Africa accounting for the large majority. The USGS platinum-group metals statistics track how tight that supply chain really is. Here is the part that trips up sellers: scarcity does not automatically mean a higher price than gold. Platinum is an industrial metal as much as a jewelry metal, with heavy demand from automotive catalytic converters, chemical refining, and laboratory equipment, so its price responds to manufacturing cycles in ways gold does not. Platinum has traded both above and below gold at different points in recent history. Benchmark prices are set through the daily precious metal price auctions, and they move every day. What that means practically: do not assume your platinum is worth less than gold, and do not assume it is worth more. Have it weighed and priced on the day you sell. At the Counter How a Platinum Appraisal Actually Works in Houston The acid tests that work on gold are unreliable on platinum, because platinum resists almost every acid you can throw at it. That is why a serious buyer reaches for electronic or XRF analysis instead, which reads the actual composition of the alloy without cutting, filing, or damaging your piece. From there it is straightforward. The item goes on a certified scale, the purity from the test is applied, and the day’s market rate does the rest. If your piece holds diamonds or colored stones, those get evaluated separately and added on top, since the setting and the stones are two different kinds of value in the same object. Every step of that should happen where you can see it. Weight read out loud, purity stated, math shown. Anything less and you have no way to check the number you are being handed. See Exactly

Palladium Buyer in Houston: The Precious Metal Most Sellers Don’t Know They Own

Palladium Buyers ยท Houston, TX Palladium Buyer in Houston: The Precious Metal Most Sellers Don’t Know They Own It looks like white gold, weighs less than platinum, and sits unrecognized in thousands of Houston jewelry boxes. Here is how to find yours. Of the four precious metals a palladium buyer in Houston handles, palladium is the one people cannot name. Gold everyone knows. Silver everyone knows. Platinum most people have at least heard of. Palladium gets called “the white one” or written off as stainless steel, which is a costly mistake, because it is a genuine platinum-group metal, jewelry-grade palladium is usually 95% pure, and it sells by weight exactly like the rest. If you got married between roughly 2004 and 2015, there is a real chance one of the bands in your drawer is palladium and you have never once thought of it as valuable. Quick Answer Palladium is stamped PD, PD500, PD950, 500Pd, or 950Pd. It is naturally white so it never needs rhodium plating, it does not tarnish, and it is noticeably lighter in the hand than platinum or gold of the same size. That surprising lightness is the giveaway: a white metal ring that feels too light to be platinum, with a PD mark inside, is palladium, and it carries real precious metal value. Identify It How to Recognize Palladium in Your Own Jewelry Box Start with the stamp. Palladium marks are short and unmistakable once you know them: PD, PD950, 950Pd, PD500, or 500Pd. The number is parts per thousand, so PD950 is 95% pure palladium. Some pieces from the United Kingdom carry a full pictorial hallmark with a Pallas head, since British assay offices began hallmarking palladium in 2010. Then pick it up. This is the part that surprises people. Palladium is roughly half the density of platinum. Hold a palladium band and a platinum band of identical size and the difference is immediate, the palladium feels almost hollow by comparison. It is also lighter than 14k gold. Then look at the color. Palladium is naturally white, a shade slightly darker and cooler than rhodium-plated white gold. It never yellows, never needs replating, and does not tarnish the way silver does. A white metal ring that has stayed exactly the same color for twenty years is not silver and is probably not white gold. Reference Chart Palladium Stamps and the Marks People Confuse Them With Take a magnifying glass to the inside of the band. Almost every white metal in jewelry declares itself if you know the shorthand.

Titanium, tungsten, and stainless steel wedding bands were sold alongside palladium in the same display cases during the same years, and they look similar. They have no scrap value. Palladium does. A thirty-second stamp check tells you which one you are holding. “Palladium is the only precious metal people routinely mistake for something worthless. Nobody throws out a gold ring by accident. Palladium gets donated in a shoebox.” The Hidden Palladium Your White Gold Ring Probably Contains Palladium Too Here is something almost no seller knows. Gold is yellow, so making white gold requires alloying it with a whitening metal. For decades that metal was nickel, which caused skin reactions in a meaningful share of wearers. Modern jewelers largely switched to palladium instead, and “palladium white gold” is now the standard for nickel-free bridal jewelry. That does not turn your 14k white gold ring into a palladium piece. It is still valued and sold as gold, at 58.3% or 75% gold content depending on the karat. But it explains something useful: if you have white gold jewelry that has never irritated your skin and has held its color unusually well, palladium is likely part of the reason, and it is a reminder that the white metals in your box are rarely as simple as they look. Palladium itself was identified in 1803 by the English chemist William Hyde Wollaston, who named it after Pallas, an asteroid discovered the year before. It sat as an industrial curiosity for most of two centuries. The Britannica entry on palladium covers its chemistry and discovery in more depth. Supply and Demand Why a Metal Nobody Recognizes Became So Valuable Jewelry is a small slice of palladium demand. The overwhelming majority goes into catalytic converters for gasoline engines, where palladium does the work that platinum does in diesel vehicles. Add electronics, dentistry, and chemical manufacturing, and you have a metal whose price is driven almost entirely by industry rather than adornment. Supply is the other half of the story, and it is tight. Palladium is mined in only a handful of places, with Russia and South Africa dominating global output, and most of it comes out of the ground as a byproduct of nickel or platinum mining rather than from dedicated palladium mines. That combination of concentrated supply and industrial demand has made palladium one of the most volatile precious metals of the last twenty years, at times trading above both gold and platinum, at other times falling well below. The USGS platinum-group metals statistics document how narrow that supply base really is. For a seller, the practical takeaway is simple: never assume palladium is worth little because you have not heard of it, and never assume last year’s price applies today. Get it weighed and priced on the day you sell. One note while we are on the subject of catalytic converters: we buy palladium jewelry, bullion, and scrap, not converters. Removing
