Why 18 karat gold?

Let's briefly get to the basics: why choose 18K gold? What is the difference between 18K and 14K, or even 10K?

The main difference between 18K, 14K, and 10K is of course the amount of pure gold within the alloy being used. As we all know, pure gold is a very soft metal, prone to nicks and scratches which make that bling... not so blingy. To combat this, gold is mixed with other - tougher - metals which give gold the back-bone it needs.
In the case of 18K yellow gold, gold accounts for 75% (more gold, more shine) while silver (16.6% or 12.5%) and copper (8.4% or 12%) account for the rest. Contrary to popular belief, 18K is not a soft metal and with the above mentioned alloys, it can rival the sturdiness of a 10K.

The higher gold content in 18K also means that wearers are less likely to encounter an adverse reaction to the metal, which occurs with lower karats, especially 10K or less.

At 18Karat, we only deal in 18 karat white and yellow gold (or platinum) because we firmly believe these are of the finest quality and durability.
