White gold has a lower resale value than yellow gold. The reason white gold is worth less than yellow gold is because alloy cost less but it also means the purity (karat) of your gold jewellery is diluted. Another big no-no is to invest in white gold. Buy it if you like it and can afford it, but not to invest in it.

Precious metals are rare, naturally occurring metallic chemical elements of high economic value. The best known precious metals are the coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage.

When it comes to how valuable they are, different elements of chemistry determine this. The precious metals include iridium, rhenium, ruthenium, rhodium, palladium, osmium, platinum, silver and gold.

The 5 Most Precious Metals on Earth

• Rhodium. Rhodium is one of the metals you will find listed on Market Spot Price, right up there with Gold, Silver, Platinum, and Palladium.
• Platinum. This identifiable metal held the throne in commodity pricing for decades until it was overtaken by Gold.
• Gold.
• Ruthenium.
• Iridium.

The most popular precious metals with investors are gold, platinum, and silver.

KDM gold on the other hand provides no guarantee on the purity and fineness of gold jewellery as it’s not certified. It’s quite simple to say that hallmarked BIS 916 gold would be the better choice when the purity is of greatest concern.

Pure gold

The higher the score, the harder the metal. Vickers hardness of 9ct gold is between 80 to 120 (depending on the other constituents of the alloy and the condition of the material). 18ct gold receives a score of between 135 to 165. So 18ct gold is harder than 9ct gold – science fact!

The 18K gold plating contains 75% of pure gold mixed with other metals for better hardness and strength, whereas the 24K gold plating is 100% pure gold. However, 24K gold is usually not used in jewelry making as it is very soft and vulnerable to damage. Additionally, 24k gold has a much more yellow color than 18k Gold.

Since ornaments in their making are required to be held tightly onto a diamond or allied precious stones, 24-karat gold is not used for making jewellery because of its softness. Thanks to the ductility and malleability of 24-karat gold, it can easily be deformed and lose its grip on a jewel.

24-carat gold

The strength of a gold chain increases with the increase in copper or silver content but optimum is 22 ct or 916 (91.6% gold). So 22 kt gold chain is a best choice for daily use. It is recommended for daily use. 24k gold, elemental gold or pure gold, is only soft compared to its alloys (22k, 18k, and 14k).

In fact, it is difficult to even get 99.99% pure gold bullion these days. The purest of gold available in the market today is 99.95% pure. 24K gold or pure gold relatively has lesser hardness….What is 22k/ 18k/ 14k in gold.

Wearing solid gold jewelry, white gold or yellow gold, in the shower will not harm the metal itself, however it can reduce the shine therefore it is not recommended. Showering with gold plated jewelry can eventually cause the gold layer to wear off completely, therefore you should definitely refrain from doing so.
