GOLD PURITY, COLOR AND CARE
Gold presents unique qualities. It is resistant to rust, tarnish, and corrosion. While being an extremely resistant element, gold is also the most malleable of all precious metals.
Pure gold is too soft for everyday use. It needs to be combined with a careful mixture of metals like silver, copper, and zinc to give it body and durability. Karatage, denoted by a number followed by "K", indicates purity; in other words, the percentage of gold in the total metal mass of a piece of jewellery. Karatage is expressed in 24ths, making 24k gold, 100% gold.
Bizzotto jewellery is created exclusively with 18k gold – an alloy with a 75% gold rate – in order to make precious yet durable pieces for everyday wear.
Bizzotto selects only very high-quality alloys that combine natural, non-allergenic metals in compliance with the european union's (eu) nickel directive.
The colour of gold is determined by two factors:
- The type of metal alloys included
- The percentage of each metal alloy
Natural gold and colour-saturated alloys are what give yellow gold jewellery its rich shine. The alloys most commonly used are red-hued copper and green-hued silver. An expert mixture of copper, silver and pure gold gives this precious metal its signature warmth.
WHITE GOLD WITH BLACK RHODIUM
Black rhodium is plated to white gold to create a rich black appearance that is extremely hard and strong. As with traditional white rhodium, black rhodium may wear away over time. Replating is a simple process that restores your jewellery's black finish.
Rose gold jewellery is created by using a copper alloy. Again, the overall percentage of metal alloys is the same for rose gold as it is for yellow or white gold – the only difference lies in the mixture of alloys chosen.
Our 18k gold jewellery is skilfully crafted into beautiful pieces to be enjoyed by whomever wears it: every day, in every occasion.
Gold is a natural element: as such, corrosive chemical products like bleach or other cleaning products can corrode it. We recommend that you remove your jewellery when using chemicals to reduce daily abrasions and extend its shine.
To clean your jewellery, use a solution of warm water and detergent-free soap in combination with a soft-bristled brush and dry it with a soft cloth. When you don’t wear it, store your gold pieces in soft cloth bags or their boxes.
To protect jewellery from scratches, avoid storing it with other pieces. Polishing and rhodium-plating can bring back the original shine of white and eliminate any marks.
