All about Gold

Posted by Carolina Mendoza on

Gold has many characteristics that make it special and valuable (and not just in an economic aspect). So here we will explain from how the purity of gold is measured, where the different colors come from, how gold is formed and what benefits does it have to use jewelry with one of the most noble metals in the universe.

What are carats?

We use carats (K) to measure the purity of gold, and it basically explains how much of an alloyed metal is gold: 24 carats means a purity of 100%, unlike 12K which is 50% and the rest is a combination of other metals.

  • 24K x 100% Purity
  • 18K x 75% Purity
  • 14k x 58% Purity
  • 10K x 42% Purity

It is important to know that gold, in its pure state, is a very malleable metal, so it is easy to deform it. That's why jewelry is mixed with other metals to give it the hardness needed to last forever.

The production standard in fine jewelry is 14K, which is approximately 58% gold. The rest are alloys that give it strength and change its color: resulting in yellow, white, or pink gold.

TIP: For those who like to use jewelry with very large stones, it is recommended that it be in 10K gold, so that it has more firmness and is difficult to fall off.

It is important to know that carats (K) are not the same as gold plated. If you are interested in learning more about the differences visit our blog post: Gold, Goldfilled, Gold Vermeil or Gold Plate which to choose?


Why are there several gold colors?

The color of gold is yellow, but it can be combined with other metals to be made of different colors such as white and pink (which are the most classic colors we find in jewelry) or even green and red!

The purer the gold the more yellow it will look; a 22K gold ring will look more yellow (albeit subtly) than a 14K gold ring.

For example, to create 18K gold of different colors we would use:

  • Yellow Gold = 75% Gold + 12.5% Silver + 12.5%
  • Copper White Gold = 75% Gold + 20% Silver + 5% Copper
  • Rose Gold = 75% Gold + 5% Silver + 20% Copper


What care does gold jewelry require?

One of the great advantages of gold is that it doesn't rust. So if it is being properly stored it can retain its amazing shine for a long time.

We recommend keeping gold pieces separately from jewelry pieces from other materials, as they may scratch or lose luster.

To clean them, you can use hot water and hand soap to eliminate grease and dirt that accumulates. Then rinse them thoroughly with water until there is no residue of soap and dry ones with hair dryer to avoid water stains.

IMPORTANT: If the gold piece has gems or gemstones you should consider that each may require special care and this cleaning procedure could NOT be applied in such cases. To see what care each stone requires, visit our Stone Care Guide.

Why does White Gold Stains?

It's not that it's actually stained, but the white gold we get from traditional jewelry is usually platinized white gold.

The platinized is a finish that is typically given to white gold to make it more similar to platinum, and consists of giving it a rhodium bath. When the gold starts to "stain" and see yellowish it really is because the rhodium bath starts to fall off and the color of the gold begins to come out.

In fine white gold jewelry it is the most common thing to give it a rhodium bath, so many people have a different idea of what white gold actually looks like.

Natural white gold maintains the warm tone of gold. One of the great advantages of leaving it natural is that it won't require maintenance to keep its color, the warm tone will make it stand out from the silver pieces and may even favor some stone colors.


Where does Gold come from?

As amazing as it may seem, the gold of the earth actually comes from the stars.

The most precious metals on our planet were formed thousands of years ago in the stars. And when they died as a supernova, they came to earth thanks to the gamma-ray explosion.

We recommend the video of TED ED "Where does gold come from? " by David Lunney. Where he explains this fascinating process in detail.

So when you wonder why gold is so scarce and valuable just remember that you bring a little piece of a star that traveled thousands of miles to get to you...

What energy benefits does it have to use gold jewelry?

Apart from the economic and practical benefits we have already mentioned; Gold is the best metal to channel energy. When used properly, it can attract different benefits to our life.

Have you heard the phrase "Dress for Success"? It is said that we must vibrate at the same frequency as what we want, so gold jewelry is an open invitation for abundance to come into our lives.

  • Buen día!!!me encontré una esclava que dice ser de 14k la lleve a un sitio que compran oro le hizo la prueba y comenzó a burbujear un color entre azul verdoso algo asi, esta persona se tomo aprox 20 minutos revisándola después de eso me comento que no era iro, sino que era metal reina, la esclava no a cambiado ni poquito su color y no quedo mancha alguna del acido.
    Sera que pueda ser quilataje mas bajo por haber reaccionado así con los ácidos o de plano no es auténtica la esclava???
    Gracias bien día.
