One hears the word 'karat' used frequently; however, there is no widespread understanding of exactly what it means exactly. The karat of a part of gold jewelry is indicated by lots as well as the letter K. American gold jewellery should be with a minimum of 10K purity (41.7% pure gold) which is typically found up to 18K (75% pure gold). Higher purity levels are less common with alloys at 22 K (91.6% pure gold), and 24 K (99.9% pure gold) being considered too soft for jewellery utilization in America and Europe. However, one does find these higher purity alloys in wide utilization in Asia, Africa, as well as the Near East. Platinum alloys range between 900 (90% pure) to 950 (95.0% pure). And the silver employed in jewellery is generally sterling silver, or 92.5% fine silver. engagement rings ireland antique
