Strength. While both gold and platinum are strong, platinum is harder. Platinum is denser than gold, which means it's more durable, and is less likely to break. That means there's a smaller risk of you losing any of the precious metal.
Platinum: Despite being nearly identical in appearance, platinum is more valuable than gold. Platinum's high price point can be attributed to its rarity and density as precious metals are often priced by their weight.
Platinum traditionally traded at a higher price than gold and combined with platinum's rarity compared with gold, “platinum” as an adjective has come to be associated with a higher level of prestige than gold.
Gold: Strength and Durability. Both gold and platinum are strong precious metals. Platinum, however, is more durable and outlasts gold because of its high density and chemical composition making it less likely to break when compared to gold.
Platinum also ranks 60% denser than gold, making it a more durable option. Over time, platinum's surface texture can change, resulting in a frosted look referred to as patina which some may find appealing or easily removed if preferred.
Platinum is generally valued higher than gold. This is because platinum is rarer than gold, has a higher density and is purer. Platinum rings require more platinum than gold rings require gold, which can increase the overall cost.
Gold prices tend to move more slowly than the price of silver and platinum, with the latter two seen as being more volatile, in part because of their wider use within industry. The best option for your own circumstances is likely to depend upon your attitude to risk and whether you are seeking a long-term investment.
To be considered platinum, a piece must contain 95% or more of the metal, making it one of the purest precious metals you can buy. Over time, platinum will fade in a different way. It won't turn yellow, like yellow gold; but, it will begin to lose its shiny finish and build a natural patina (more on this in a bit).
If you look at the material value of precious metals, platinum sits at the top. The shiny white metal is considered a strong symbol of value and quality. The supply of platinum is much lower vs that of gold. It's also far more difficult to extract than the yellow metal.
Platinum - the chemical symbol PT - is classed as a 'noble' metal. This means it is unreactive, and pure Platinum will not tarnish, corrode, rust, or change colour over time. Platinum alloys of course could change this, depending on the metal(s) used, and the purity of the alloy.
The metals that jewelers come in contact with include gold, copper, silver, zinc, iron, steel, platinum, palladium, rhodium, iridium, titanium, niobium, aluminum and ones that we should consider not having around any more at all in the workshop: nickel, lead, mercury, chromium, selenium, cadmium, arsenic, antimony.
Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well.
If translated into numbers, platinum—for all of its known deposits—is considerably more rare than gold and is the rarest metal of all.
Palladium, by itself, is great for jewelry production. Its malleability makes it excellent for holding diamonds in place while still being durable enough to resist scratches better than platinum or white gold. Since it's naturally white, there's no need to rhodium-plate, so it's lower maintenance.
Palladium and platinum are always harder than gold alloys and silver. Palladium is less dense than platinum, so platinum is the most durable metal overall. The best rule of thumb is to always wear the same metal and carat next to each other for even wear over time.
Platinum is a quiet luxury, not flashy or obvious. The weight of it makes it feel substantial, but it's preciousness can be your own little secret. Its color, the most neutral of the precious metals, makes it perfect to set off both diamonds and color gemstones.
Additionally, this natural density and weight of Platinum – as Platinum is 25% heavier than gold – are characteristics that make it more durable than other jewelry metals. Platinum does not wear away and holds precious stones firmly and securely. In short, Platinum prongs are better protection for diamonds.
1. RHODIUM: TOP MOST VALUABLE METAL. Rhodium is the most valuable metal and exists within the platinum group of metals.
One disadvantage associated with platinum jewelry is its high cost relative to other types of metals, such as Gold and Silver.
Similarly, diamonds are porous and can absorb water, which can cause the stone to become discolored or cloudy. On the other hand, platinum is a strong, durable metal that is less likely to be damaged by water.
PRICE & VALUE
However, white gold jewellery can be slightly more expensive than yellow gold jewellery, because of the manufacturing process it undergoes while being mixed and coated. At the end of the day, choosing white or yellow gold is mainly a question of personal preference.
Precious metals like gold are just one option available to you. But all investments come with their risks. Platinum carries greater volatility than other choices, making it more susceptible to price drops. Meanwhile, gold is relatively stable, but it may not be a strong hedge against inflation over the short term.
Gold has long been considered a safe haven asset due to its limited supply and historical stability. It's also seen as a hedge against inflation and currency devaluation, which makes it especially appealing during periods of economic uncertainty.
Platinum jewelry is a bit iffy, since it tends to be more difficult to sell. How much you'll get for platinum in this form is often dependent on current market conditions and other economic factors. Plus, platinum jewelry, regardless of market factors, tends to be only worth its refining or smelting value.
