The same holds true for the gem and jewelry industry: For years a global manufacturing hub, China is emerging as the strongest consumer market for luxury products such as jewelry. Chinese consumers are now synonymous with luxury products, and this is true with gemstones and jewelry.
Pure gold is so soft it is rarely used in jewelry. Jewelers deal with various gold alloys, collectively called karat gold. Karat (K) tells the number of parts, by weight, of gold in 24 parts of alloy. The higher the percentage of pure gold, the higher the karat. Pure gold is 24K; 18K is 18 parts fine gold and 6 parts metal; 14K is 14 parts fine gold and 10 parts metal; and 10K is 10 parts fine gold and 14 parts other metal. A diamond certificate is a report that attests to the authenticity of a diamond.
24 Karat gold is the purest gold you can get in gold bullion, coins, bars or gold jewelry. Coins should originate from a Mint. Smaller items such as rings and other gold jewelry should have an assay mark, or hallmark to show the purity of the gold. Bars and ingots should originate from a foundry.he carat (abbrev ct or K) is a measure of the purity of gold. In the US and Canada the spelling karat has been adopted solely for the measure of purity and carat referring to the mass weight.
