Word Origin

Platinum is derived from the diminutive Spanish word platina meaning little silver. Historically, platinum was used as commonly as other metals like gold and silver, especially in jewelry-making.

Platinum in Ancient Egyptian Tombs

According to archaeologists, in 1200 BC, the gold used in ancient Egyptian tombs had small platinum amounts. As an example, a little box adorned with gold-platinum hieroglyphics was discovered in Shepenupet II’s tomb. Nevertheless, ancient Egyptians were aware that their gold had some platinum is still a mystery to be solved, and there’s a chance they didn’t know it was there all this time.

The Natives of Esmeraldas

Even before Christopher Columbus set foot in the New World, the natives close to the present-day Esmeraldas, Ecuador, had already produced artifacts forged from the alloy of platinum and white gold; thus, these people are credited with the discovery of platinum.

The pre-Columbian practice of platinum-smith by the South American natives is historically attributed to the Tolita Culture; however, the exact date and location can hardly be determined as the most platinum discovered from that area were acquired through trade, not archeological sites.

European Discovery

Countless Europeans journeyed into the southern part of the New World because of platinum and accumulated more knowledge about it as they encountered the natives. At first, platinum was considered a kind of impurity in gold and was thus disposed of. As a matter of fact, an official decree that prohibited mixing gold with platinum was even implemented.

In 1557, the first known text on platinum was written by the Italian humanist Julius Caesar Scaligern, who, in his text, described platinum as an unknown noble metal that was discovered in the mines between Panama and Mexico and as something neither fire nor Spanish arts could liquefy.

Then, after Antonio de Ulloa had returned from Colombia and Peru and had taken whitish metal nuggets to Spain, he built the first mineralogy laboratory in Spain in 1748 and became the first to study platinum. Moreover, during his expedition, he wrote a brief account of platinum. He described it as something that could be neither separated nor heated in high air or oxygen temperatures.

In 1783, a method that produced workable platinum was invented and patented by the French chemist Francois Chabaneau despite the metal’s inconsistent quality produced in every batch.

Because of his further studies in platinum ores, the other members of the platinum-group metals were discovered and caused Chabaneau’s work frustration.

What Platinum Is

Platinum is a silverish-white metal that belongs to the platinum-group metals (PGMs), palladium, rhodium, osmium, iridium, and ruthenium shared chemical properties and presence in mineral deposits. Additionally, platinum has a high melting point and is nontoxic, malleable, and ductile.

Platinum Characteristics

Platinum is a valuable and desirable metal used in various ways, such as in magnets, medication, electrical parts, and most especially in jewelry. 

It was also known as white gold due to its silvery-white coloring.


Platinum is hard and durable, making it more malleable. It is frequently and commonly mixed with other metals (i.e., copper, palladium, rhodium, iridium, and titanium).

To determine how pure platinum is in an object, hallmarks are used and are quite similar to karat, the unit of measurement for gold’s purity. Moreover, to do so, PLT, PLAT, or PLATINUM are inscribed on objects made of platinum and combined with a parts-per-thousand number (e.g., 900PLAT).

In terms of purity, platinum has 1000 parts, so it is obvious that a jewelry piece made of platinum is purer than gold and silver. In other words, a platinum ring’s purity is as pure as an 18K gold ring having about 1/1000th of a millimeter purity or about 1000 parts per million. Still, only a small amount of metal is needed to be mixed with platinum to make it hard enough for jewelers.


Below are the kinds of platinum-based on purity:

  • A jewelry piece with a 999PLAT mark has 99% pure platinum.
  • A 950LAT mark is 95% pure platinum mixed with 5% other metal alloys normally, cobalt, copper, iridium, palladium, or rhodium.
  • One with a 900PLAT mark is 90% pure platinum and 10% other metal alloys, normally, ruthenium or iridium.
  • One with an 850PLAT mark is 85% platinum, and the other 15% are other metal alloys.


Necklaces are jewelry worn around the neck. It is one of the earliest known adornments worn by humans that dates back to prehistoric times. They are often used for several different purposes, such as funerals, magic, or religious ceremonies. They are also used as symbols of wealth as they are typically made of precious metals and stones.

There are many types of necklaces, and they are commonly classified by length:


Like its namesake, a choker is a tight-fitted (typically 14 inches to 16 inches long) necklace worn around the neck. Chokers can be from a wide range of materials such as leather, latex, plastic, metal, and a lot more. They can also be decorated with pendants, studs, gemstones, or sequins.

Princess necklace

A princess necklace is longer than a choker and usually sits just below the collarbone. It is typically 18 to 20 inches long and is believed to be the most flattering length, accentuating the wearer’s features. 


Sits between the collarbone or at the center of the chest, matinee necklaces are typically 22 to 23 inches long and are great for layering. They are best worn with a high neckline as they draw attention directly to the chest area.

Opera necklace

Falls right below the bust, this type of necklace is typically 26 to 30 inches long and is a piece of very versatile jewelry that can be looped twice or worn as it is.

Rope necklace

A rope necklace is any necklace that’s longer than the opera necklace. It can be worn draped multiple times around the neck, and it gives an illusion of multiple necklaces.

Platinum necklaces never go out of trend as it is a timeless piece that will last for a lifetime. 

A-list celebrities wear platinum necklaces during red-carpet events as it brings out an elegant and glamorous feel. Platinum is also the best metal to hold diamonds and other precious stones as it holds it securely compared to other metals.
