    Understanding Gold Karat Weight

    Jewellery can be made from a range of gold carat weights. Carat weight is used to determine the amount of gold in a piece of jewellery.

    Pure gold (24k gold) is very soft and isn't always practical to use alone in fine jewellery. For this reason, it's combined with other metals for durability. Karat is the measurement of gold's purity; it indicates the volume of pure gold in an alloy.

    18k Gold

    Why do we recommend 18k gold?

    18 karat gold is 18 parts pure gold or 75% pure, hence the stamp 750 found inside pieces made from this alloy. You may also find the letters 18k engraved inside a ring. At Orsini Fine Jewellery we predominantly use 18 karat gold as our ‘gold standard’. 18k gold is strong, has a beautiful hue, durable and is less likely to tarnish, corrode or react with the owner's skin.

    18k gold is a better metal for master goldsmiths to work with and creates finer quality jewellery.

    This is an ideal metal alloy for making fine pieces of jewellery such as engagement and wedding rings that will be treasured for a lifetime and passed on to future generations.

    9k Gold

    What are the benefits of 9k gold? Whilst 9k gold is technically harder than 18k gold, this doesn't mean it's more resilient in the long-term. 9k gold is in fact more brittle, which means it's less resistant to knocks and scratches on a microscopic scale when compared over a longer period of time. 9k gold also contains a higher proportion of other metals so it will tarnish over time. Depending on which metals are used to make the alloy, it’s also much more likely to cause a skin reaction in some people. However, it should be noted that at Orsini the Italian jewellery does not contain nickel.

    With this said, there are reasons to opt for 9k gold. It’s a popular choice for men’s wedding bands and it’s also perfect if you’re on a limited budget. And if you look after it and clean it often, re rhodium plate regularly (if white gold) it’s certainly going to last well. 14k gold is a better alloy than 9k gold as it has more gold content.

    Platinum Group

    The platinum group metals are made up of platinum, palladium, rhodium, ruthenium, iridium, and osmium.

    At Orsini we have some incredible pieces that contain either platinum, palladium, rhodium, or ruthenium. These metals are more dense than gold, with high melting points, high heat resistance, and high corrosion resistance, making them the toughest metals used in jewellery.

    At Orsini we offer platinum and palladium options for the majority of our wedding rings.
