1.About platinum
Platinum is a popular metal among diamond engagement rings and wedding rings. The natural white light of platinum will never fade or change color, and highlights the brightness and sparkle of the diamond. Platinum will maintain a lasting luster, making it an ideal symbol of true eternal love.
Density and durability
Platinum is durable. Its density makes it a secure setting for your diamond or precious gemstone. All our rings are made with platinum ring claws to set loose diamonds. Because platinum is a natural white metal, it does not need to be replated, and it can maintain its ideal state for a long time.
Platinum’s Green Rust
Although platinum is the strongest kind of jewelry metal, it can scratch and wear out green rust. Green rust is considered by many to be a very unique and desirable characteristic. However, you can easily restore the light and reflective luster before the green rust is generated just by polishing it with a soft cloth.
The purity of platinum
Platinum jewelry is very rare, actually 30 times more precious than gold. The purity of our platinum is 95% (5% iridium, palladium, ruthenium and other alloys). Its purity makes it a natural low-sensitivity metal, which is very suitable for those with sensitive skin problems.
How to maintain the metallic luster of platinum
It’s very simple. Simply soak the platinum in a mild soap and warm water solution, and then gently wipe it with a soft brush.
2.Gold purity
Gold is the most malleable of all precious metals, so it is very suitable for detailed and complex designs. In addition, it is not easy to rust, age and corrode. Pure gold is very soft and cannot withstand daily wear and tear, so silver, copper and a little zinc are added as alloys to give it strength and durability. This can make the finished product harder and spread across multiple generations.
18K gold is an alloy of 75% gold and other metals, and its strength is suitable for daily wear, while 14K gold is an alloy of 58.3% gold and other metals. The United States allows the lowest K number to be sold as a gold jewellery of 10K-that is, an alloy with a pure gold content of 41.7%. If you belong to a European customer, you may use different gold K numbers for measurement. 585 is equivalent to 14K gold, and 750 is equivalent to 18K gold.
Although the color of pure gold is yellow, gold ornaments or pieces of gold are almost all alloys. The metal that the alloy matches will change its color to a variety of tones, depending on:
The type of alloy it contains
Percentage of each alloy
Metals that alloy with gold include: zinc, copper, nickel, iron, cadmium, aluminum, silver, platinum, and palladium.
Our high-end metals are available in 3 colors: gold, white gold and rose gold.
What is gold?
Silver, copper, and pure gold (and a little zinc) give gold jewelry a rich brilliance. Although the proportion of each metal used to make the alloy is different, all formulas are based on 18K gold containing 75% pure gold and 14K gold containing 58.3% pure gold. This metal shines with classic warm light and is especially suitable for low-color diamonds with a faint yellow hue.
If you are interested in 14K gold, which has a slightly lighter color than 18K gold, you must pay attention to the difference in color, durability and hardness between the two K numbers. 18K gold is softer and easier to show scratches. 14K gold is harder and more wear-resistant.
What is platinum?
In order to show the modern silvery white color of platinum jewelry, pure gold is often alloyed with a mixture of nickel or palladium and silver, plus other alloys with whitening effects. Afterwards, a particularly hard element called rhodium is used for plating (the surface is covered with a layer of other metals). Although the rhodium-plated surface is relatively durable, it may sometimes need to be re-plated. It is normal for platinum jewelry to turn into a pale champagne color after a few years. This means that your jewelry needs to be resurfaced to restore its original white luster. We recommend regular cleaning and annual maintenance. If you want to replace a ring purchased at Blue Nile, please contact our professional diamond and jewelry consultants.
What is rose gold?
The romantic pink hue of rose gold jewelry is created using copper alloys. The higher the copper content in the alloy, the more rose red the hue. The content of pure gold in rose gold is the same as that of gold or platinum. The difference lies in the proportion of other metals that make up the alloy. Rose gold is a beautiful and unique choice for engagement rings. Its modern retro charm has become a trendy hot spot in recent years. Customers prefer a certain type of K gold. In the final analysis, they prefer lighter (18K) or darker (14K) rose gold to make their setting or ring
3.Silver--Pure silver is relatively soft, malleable and easily damaged–not suitable for making jewelry. To prevent deformation or damage, silver is often combined with other metals to make it more durable
What is 925 sterling silver? 925 sterling silver is an alloy often used in jewelry. It must contain at least 92.5% pure silver, and the remaining 7.5% can be any other metal.
How to properly care for 925 sterling silver jewelry?
To avoid scratches and other damage as much as possible, place the silver jewelry in a separate compartment in a cloth bag or jewelry box. Avoid exposing silver jewelry to household chemicals such as bleach or ammonia, or swimming in chlorinated water with silver jewelry, because these chemicals can damage 925 sterling silver.
If you want to clean silver jewelry, please use a soft cloth with a gloss agent specially formulated for rust removal. You can find high-quality silver gloss agents, solvents or suitable cloths to remove silver rust in hardware stores or specialized craft shops. If necessary, ask local silversmiths to rhodium-plat the silver jewellery so that the silver jewellery can restore its original luster.
4.Tungsten carbide has unique charm, is hard and wear-resistant, and is a forged metal with long-lasting properties. Tungsten carbide jewelry is made of an alloy containing 80% elemental tungsten and 20% carbon mixed with other metals.
Nursing —Since tungsten and carbon are natural elements, this jewelry will be affected by strong chemicals such as chlorine or other cleaning products. To clean tungsten carbide jewelry, you should use a mixed solution of warm water and detergent-free soap, and use a soft wipe.
5.Cobalt jewelry is made of a highly durable alloy, which is four times harder than platinum jewelry and has a lower density. Due to its natural hardness, cobalt jewelry has very good scratch-resistant, shatter-resistant and corrosion-resistant properties. Because cobalt has a smaller density and natural malleability, it is possible to design a powerful and dynamic design with a lighter weight. Cobalt also has low sensitivity, so it is ideal for people with sensitive skin or those with an active lifestyle.
6. Titanium is a unique and strong metal, which is particularly affordable for men’s wedding rings. With a solid foundation in the engineering and aerospace industry, titanium has a good record as a durable metal. Our men’s titanium ring is 99% pure, nickel-free, and hypoallergenic.
Titanium is quite light, so it is easy to wear and suitable for active people.
To clean titanium jewelry, use a soap solution mixed with warm water and detergent-free, and use a soft wipe. When not wearing them, store the titanium jewelry separately in a soft cloth bag or original box to avoid the influence of daily irritating elements.
