See below four common questions about GOLD answered (price, Karats and colour of Gold), to understand better your jewels!
- Why is Gold expensive?
Gold is a precious metal because it is rare and difficult to extract from Earth. Gold is the rarest of precious metals, making only 4 parts per billion of Earth’s crust.
(To put this number into perspective, iron makes up to 5,6 per cent of the Earth’s crust, making iron common and inexpensive).
- What is the Karat?
The term Karat (spelled with a ‘K’) is used to state gold’s fineness, which is based on parts out of 24.
DO NOT CONFUSE with Carat (spelled with a ‘C’), which is a measure of gem’s (eg diamond’s) weight.
- Which Gold is the best? 18K or 14K?
What is 18K (Karat) Gold?
18K is a Gold alloy containing 18 out of 24 parts (or 750/1000) pure gold, and 6 out of 24 other metals.
What is 14K (Karat) Gold?
14K is a Gold alloy containing 14 out of 24 parts (or 585/1000) pure gold, and 10 out of 24 other metals.
- As 18K includes a higher percentage of gold it is more expensive than 14K.
If the colour of Gold is Yellow, how can we have White Gold? Or Rose Gold?
Mixing Gold with other metals, to achieve 18K or 14K Gold, we can customise Gold’s colour.
The ingredients of the typical gold alloys are the following:
14K/18K yellow gold: Gold, copper, silver, zinc
14K/18K white gold: Gold, nickel or palladium, copper, zinc
14K/18K rose gold: Gold, copper (increased amount), silver
