Rm 011 Rose Gold

[Emerenciana Mcgreal]

Rosegold is a blend, or an alloy of pure 24 karat yellow gold, copper and silver. Pure 24 karat yellow gold is the base for all gold colors and qualities, but is too soft to be used in a pure state for jewelry. It needs to be blended, or alloyed with other metals to strengthen it enough to wear. Different alloy recipes are used to color and determine all types of metal made into jewelry including platinum, white gold, yellow gold and rose gold.

The depth of color in the rose gold depends on the ratio of yellow gold to copper. Less yellow gold , and a higher copper content will result in a more reddish rose color. As an example 14K rose gold is more of a rose pink color than 18K rose gold due to the higher yellow gold content in 18K. To create our lush red gold color known as rose or red gold, our 14 karat yellow gold is an alloy of 58.30% 24k yellow gold, 33.5% copper and 8.20% percent silver. Our 18 karat rose gold is a the color of a soft champagne rose, with gold undertones as the alloy is 75% 24k yellow gold, 22.2% copper and 2.8% silver.

Rose gold is a subtle, romantic color of gold that translates into romantic, elegant fine jewelry and engagement rings. We love creating designs in rose gold, and look forward to creating the perfect rose gold engagement ring, or fine jewelry piece for you!

Colored gold is the name given to any gold that has been treated using techniques to change its natural color. Pure gold is slightly reddish yellow in color,[1] but colored gold can come in a variety of different colors by alloying it with different elements.

The word white covers a broad range of colors that borders or overlaps pale yellow, tinted brown, and even very pale rose. White gold is an alloy of gold and at least one white metal (usually nickel, silver, platinum or palladium).[4] Like yellow gold, the purity of white gold is given in karats.

White gold's properties vary depending on the metals used and their proportions. A common white gold formulation consists of 90% wt. gold and 10% wt. nickel.[3] Copper can be added to increase malleability.[2] The alloys used in the jewelry industry are gold-palladium-silver and gold-nickel-copper-zinc. Palladium and nickel act as primary bleaching agents for gold; zinc acts as a secondary bleaching agent to attenuate the color of copper.[citation needed] As a result, white gold alloys can be used for many different purposes. Nickel alloys are hard and strong, and therefore good for rings and pins. Gold-palladium alloys are soft, pliable, and good for white-gold gemstone settings. The strength of gold-nickel-copper alloys is caused by formation of two phases: a gold-rich Au-Cu, and a nickel-rich Ni-Cu, and the resulting hardening of the material.[2]

The nickel used in some white gold alloys can cause an allergic reaction when worn over long periods (also notably on some wristwatch casings).[5] This reaction, typically a minor skin rash from nickel dermatitis, occurs in about one out of eight people; because of this, many countries do not use nickel in their white gold formulations.

Rose gold is a gold-copper alloy[7] widely used for specialized jewelry. Rose gold, also known as pink gold and red gold, was popular in Russia at the beginning of the 19th century, and was also known as Russian gold.[8] Rose gold jewelry is becoming more popular in the 21st century, and is commonly used for wedding rings, bracelets, and other jewelry.

Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content: the higher the copper content, the stronger the red coloration. Pink gold uses the least copper, followed by rose gold, with red gold having the highest copper content. Examples of the common alloys for 18K rose gold, 18K red gold, 18K pink gold, and 12K red gold include:[3]

During ancient times, due to impurities in the smelting process, gold frequently turned a reddish color. This is why many Greek and Roman texts, and some texts from the Middle Ages, describe gold as "red".[citation needed]

Green gold was known to the ancient Persians as long ago as 860 BC under the name electrum, a naturally occurring alloy of silver and gold.[3] However, electrum was used even thousands of years before that, by both the Akkadians and Ancient Egyptians (as evidenced by the Royal Cemetery at Ur). Even the tops of some Egyptian pyramids were known to be capped in thin layers of electrum. It actually appears as greenish-yellow rather than green. Fired enamels adhere better to these alloys than to pure gold.

Cadmium can also be added to gold alloys to create a green color, but there are health concerns regarding its use, as cadmium is highly toxic.[9] The alloy of 75% gold, 15% silver, 6% copper, and 4% cadmium yields a dark-green alloy.

Gray gold alloys are usually made from gold and palladium.[citation needed] A cheaper alternative which does not use palladium is made by adding silver, manganese, and copper to the gold in specific ratios.[10]

All the AuX2 intermetallics have the fluorite (CaF2) crystal structure, and, therefore, are brittle.[2] Deviation from the stoichiometry results in loss of color. Slightly nonstoichiometric compositions are used, however, to achieve a fine-grained two- or three-phase microstructure with reduced brittleness. Another way of reducing brittleness is to add a small amount of palladium, copper, or silver.[11]

The intermetallic compounds tend to have poor corrosion resistance. The less noble elements are leached to the environment, and a gold-rich surface layer is formed. Direct contact of blue and purple gold elements with skin should be avoided as exposure to sweat may result in metal leaching and discoloration of the metal surface.[11]

A surface plating of blue gold on karat gold or sterling silver can be achieved by a gold plating of the surface, followed by indium plating, with layer thickness matching the 1:2 atomic ratio. A heat treatment then causes interdiffusion of the metals and formation of the required intermetallic compound.

More recently, black gold can be formed by creating nanostructures on the surface. A femtosecond laser pulse deforms the surface of the metal, creating an immensely increased surface area which absorbs virtually all the light that falls on it, thus rendering it deep black,[16] but this method is used in high technology applications rather than for appearance in jewelry. The blackness is due to the excitation of localized surface plasmons which creates strong absorption in a broad range in plasmon resonance. The broadness of the plasmon resonance, and absorption wavelength range, depends on the interaction between different gold nanoparticles.[17]

Pump a generous amount of product onto your palm to apply. Apply one layer, let it absorb and then apply another layer evenly 15 minutes before sun exposure. Reapply every 2 hours.

Precautions: For external use only. Do not use on damaged or broken skin. When using this product keep out of eyes. Rinse with water to remove. Stop use and ask a doctor if rash occurs. Keep out of reach of children. If swallowed, get medical help or contact a Poison Control Center right away.

I have been wanting to try this and was so excited when shipping to Canada became available. This is my favourite everyday sunscreen! I apply it after my morning shower, and it does double duty as a moisturizer and sunscreen. The only caution is to read the fine print - you need to apply 2 coats for it to work effectively as a sunscreen. The glow is subtle, and it feels light going on.

I love the rose gold sunscreen. Who knew you could rub on such beauty while applying your sunscreen all over your body. It gives me hydration and a beautiful glow at the same time. It protects me from the damaging sun. I highly recommend this product..
