OUR METALS

Porana uses 14K, 18K solid gold, Platinum950 and Silver925

Gold

Purity

Pure gold is too soft for everyday wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Karatage, denoted by a number followed by "k" indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold, 100% gold which is too soft for fine jewelry. We craft our jewelry using both 18k and 14k gold. 

Color

The color of gold is determined by two factors:

  • The type of metal alloys included

  • The percentage of each metal alloy

Yellow Gold

Natural gold and color-saturated alloys are what give yellow gold jewelry its rich shine. The alloys most commonly used, are copper with a red hue, and silver featuring a green hue. An expert mixture of copper, silver and pure gold gives this precious metal its signature warmth.

White Gold

A silvery white character is what makes white gold jewelry so appealing. In order to make the gold white, it is combined with metal alloys that are white in nature and plated with an extremely hard element called rhodium. Although strong, rhodium may wear away over time. Replating is a simple process that can be done to restore whiteness to your jewelry.

Rose Gold

The beautiful pink hue of rose gold jewelry is created by using a copper alloy. Again, the overall percentages of metal alloys is the same for rose gold as it is for yellow or white, there is just a different mixture in what alloys are used.

Care

Since gold is a natural element, it is affected by harsh chemicals such as chlorine or other cleaning products. We recommend that you remove your jewelry when using chemicals to reduce daily abrasions and prolong the luster. To clean gold jewelry, use a solution of warm water and detergent-free soap with a soft-bristled brush. When not worn, store your gold pieces in soft cloth bags or the original box to protect them from the elements of daily exposure.

 

Platinum

Platinum’s naturally white sheen will never fade or change color, and accentuates the sparkle and brilliance of a diamond. Platinum will last forever, making it the ultimate symbol for true, enduring, and everlasting love.

Density and Durability

Platinum is durable. Its density makes it the most secure setting for your diamond or precious gemstone. All our platinum rings are crafted with platinum prongs for setting loose diamonds. Because platinum is a naturally white metal, re-plating is unnecessary; it will always hold its beauty.

Platinum's Patina

Though it is the strongest of jewelry metals, platinum can incur a scratch and develop a patina of wear. The patina is considered by many to be a unique and often desirable attribute. However, the pre-patina shine and reflective luster can easily be revived by merely buffing it with a soft cloth.

Purity of Platinum

Platinum jewelry is very rare; in fact, 30 times more so than gold. Our platinum is 95% pure (5% iridium, palladium, ruthenium, and other alloys), and its purity makes it naturally hypoallergenic, ideal for those with sensitive skin issues.

Care

How to Maintain Platinum's Metal Luster - It's easy. Simply soak platinum in a mild solution of warm soapy water, and then gently scrub it with a soft-bristled brush.

Silver

Pure silver, also called fine silver, is relatively soft, very malleable, and easily damaged so it is commonly combined with other metals to produce a more durable product. The most popular of these alloys is sterling silver, which consists of 92.5 percent silver and 7.5 percent copper. Although any metal can make up the 7.5 percent non-silver portion of sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness and durability without affecting its beautiful color. The small amount of copper added to sterling has very little effect on the metal's value. Instead, the price of the silver item is affected by the labor involved in making the item, the skill of the craftsperson, and the intricacy of the design.

Stamps of Quality

Most high quality silver items are stamped with a "fineness" or "quality" mark. This mark designates the precious metal content of the jewelry, and under federal law, must be accompanied by a maker's mark or registered trademark.

Our silver jewelry is plated with 14k gold, rose gold, rhodium and black rhodium

Care

With proper care, your fine quality silver will last a lifetime. To minimize scratches and other damage, store your silver jewelry either in a cloth pouch or in a separate compartment in your jewelry box. Avoid exposing your silver to household chemicals when cleaning with bleach or ammonia, or when swimming in chlorinated water, as these chemicals can damage silver.
