Choice of Metals for Engagement Rings
Pure 24k Gold
Pure 24k gold is very soft for jewellery and everyday use and has an orange yellow colour. It is alloyed with other metals for durability. The alloy also changes the colour and drops the purity from 24k to 18k, 14k or 9k with 18k being more suitable for engagement rings.
White gold is pure gold alloyed with nickel or palladium. When alloyed with nickel the metal turns in to a grayish colour with yellowish tint. When gold is alloyed with palladium it turns in to an off-white colour. At Joseph George Jewellery we use Palladium based white gold which is a better metal and non allergic. As a final finish white gold is rhodium plated to give it that bright white colour you see on white gold rings. Over time this plating wares out and the ring has to be re-polished and re-plated.
