Heirloom London offers 18Kt gold and platinum for all its jewellery. In addition, some non bridal, non-bespoke pieces come in other metals. The name Heirloom is a promise of quality, longevity and preciousness. In specialising in platinum and gold, Heirloom are ensuring that their jewellery lives up to their name by the ultimate white and yellow precious metals
UK platinum jewellery is mainly offered at a finesse of 950, which means that 950 parts per thousand are pure platinum. People with sensitive skin tend to get along well with platinum jewellery, the metal being hypoallergenic.
Platinum is actually heavier than lead in weight. It isn’t great for big chunky earrings as it will drag on the earlobe. But nothing makes jewellery feel precious like platinum, the weight is very reassuring.
Over time, platinum develops a natural patina, which gives it more of a matte finish. Wearers can choose to have the metal re-polished again, the patina forms because the surface of the metal shifts over time. This is why platinum does not wear away like other metals.
Gold is a lustrous warm yellow shade, but it can be mixed with copper which produces an attractive pink/red finish and is known as rose gold. You can read more about white gold below.
We mainly offer 18Kt gold jewellery at Heirloom, which is 750 parts pure gold, per thousand. We offer 9Kt gold by special order.
Gold is easy to keep shiny, which is partially because the metal surface lends itself to micro scratching, which means the metal is permanently being polished. This is also why gold jewellery does wear away after decades of wear.
Heirloom can make white gold available, but we don’t offer it as standard for bridal rings. Our rationale is simple, it is impossible to make white gold truly ‘white’ and maintain high gold purity. White gold is often rhodium plated, to give its high white lustre. Over time this wears off. For engagement and wedding rings which are going to be worn daily, this means that every 1-2 years the ring will require re-plating. So within about 3-5 years time, the difference in cost of having bought a platinum ring will be lost, and you’ve had to give your ring up 3-5 times. We make it easier, and recommend platinum as the best long term option. However, if you prefer the warmer shade of white gold which has not been rhodium plated, we are happy to offer this.
