Rose Gold vs Yellow Gold



everybody thinks gold must be yellow in colour....

yupp... it's true... pure gold is yellow..

but this pure gold can be turned into various colours by mixing it with another element....

by "alloying " the gold... yet the gold is still pure!!!



i'm sure each and everyone of us must have heard the term "alloy" atau dalam bahasa melayu adalah "ALOI"


so y do we need to alloy this pure gold....

can't we just leave them yellow, as most people like it that way...???


simple answer is that pure gold (24K) is very2 soft... therefore is not suitable to tie the diamonds all in order to make such a nice jewelry...




for example,

white gold---is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. A common white gold formulation consists of 90 wt.% gold and 10 wt.% nickel.


Rose gold --- is a gold and copper alloy widely used for specialized jewelry. It is also known as pink gold and red gold. As it was popular in Russia at the beginning of the nineteenth century, it is also known as Russian gold.

The common alloy for rose gold is 75% gold and 25% copper by mass. (18k)


There are few more colored gold--- blue , green, purple, grey as well as black gold.. in which every one of them is alloyed to certain other elements/metals to make such colors....




Therefore, points to remember....
All types of solid gold are alloys. Pure gold smelt is much too soft to be practical as currency or for forming into jewelry. Even the highest grade of yellow gold is mixed with alloy elements so that it can be easily handled. Without this knowledge, you might assume that pure yellow gold is more valuable than any colored gold. This is not true. The value of every type of gold is determined by how much gold it actually contains. Therefore, rose gold that contains 18 parts of gold is just as valuable as yellow gold that contains 18 parts of gold.



Gold classifications according to karat...


  • 100% = 24k

  • 90-92% = 22k

  • 75% = 18k

  • 58% = 14k

  • 38% = 9k

humm.... considering rose gold to be favourite collections....

risik2 kat kedai2 emas aritu, rose gold ni nampak lebih menarikk....

hummmm....
