Jewelry Markings For Platinum

Jewelry markings for platinum is used to indicate the quality of the metal alloy, including both the absence or presence of other metals. Identifying these marks can be extremely important because they have a direct impact on how much your piece of jewelry is worth and how it will last over time.

Platinum is usually marked with “PLAT” or “900MF” but there are other numbers and abbreviations that indicate the purity and amount of other metals in the alloy (such as gold, silver, palladium, and even some alloys that contain nickel). This article will give an overview of these different jewelry markings for platinum and what they mean regarding purity and cost.

Platinum Quality Mark Grade System: What The Numbers Mean To determine a certain piece of jewelry’s purity and value, many countries utilize a two – or three-digit grade system. These grades range from 1 through 999 and represent how pure the item actually is. Typically, this number appears alongside the word “plat” (or platina) which indicates that this particular piece was created using only platinum metals.

Generally speaking, higher numbers within this range denote more pure items with higher values and vice versa depending on which country you are looking at these grades within. For example, Japan has different jewelry marking standards than Europe does so it’s important to keep this in mind when investing in pieces containing rare metals like platinum.

Other Markings: Universal Jewelry Designators In addition to any two – or three-digit number code indicating quality associated with platinum jewelry pieces, there are universal designators recognized across most major countries throughout the world today as well.

Some commonly seen designators include 600Pt for 60% rotation platinum color effect; 950Pd for 95% rotation palladium color effect; SL/SB/SV for Platinum/White Gold/Rose Gold color combination effects; AUSUIS PALLADIUM BRITISH STANDARD (AB PBS) for an alloy containing up to 95% Platinum content; WFF 10KARAT GOLD PLATED means 10 karat Gold plating stretched over steel core construction amongst many others.

These abbreviations may not always appear alongside any actual quantity or grade code but can be useful in determining specific characteristics of certain coveted pieces should one ever come across them at auction or retail shop.

What are Platinum Jewelry Markings and How To Identify Them?

Platinum is the most precious metal used to make jewelry and has been popular for centuries. It’s a strong, malleable metal with a rich white color, making it an ideal material for many high-quality pieces of jewelry. As with gold and silver, jewelers use various markings and stamps on their jewelry to denote the type of metal each piece is made from.

Platinum jewelry will often have a stamp somewhere on the piece that pays tribute to its origin or purity. Here’s what you need to know about these platinum markings and how to identify them:

  • Hallmark – The hallmark on a piece of platinum jewellery indicates its origin and fineness. In Europe, the hallmark will usually consist of three parts: the first two sections are numbers indicating the percentage fineness (example: 950) while the third part is an identifying symbol specific to each country.
  • Pt – Pt stands for ‘platina’ which is Latin for ‘little silver’. Pt marks accompany hallmarks on European-made platinum pieces.
  • 900, 950, 999 – These numbers indicate the percentage purity of platinum jewelry; 900 being 90%, 950 being 95%, and 999 being 99%. The higher number indicates more valuable pieces as there will be more actual platinum in them.

The PT mark simply stands for ‘platinum’ and can be found on older pieces without any other hallmarking present. In some cases, jewellers may also include specific trademarks such as “PP” or “PT/PM” instead of Pt indicating that it’s Platinum Platina metal or Platinum Palladium respectively. Additionally there are other symbols found on certain pieces like diamonds shown with arrows signifying they are genuine diamonds set in Platinum.

Some modern earrings and rings may also come stamped wiht an insignia that resembles a four leaf clover or square; this marks the fact that it was made from recycled materials since recycled metals can be used in combination with new metals when making Jewelry today. Jewellers must obtain permission from government agencies before using any forms of recycled content in order to ensure responsible practices are followed through out manufacturing process.

In addition to standard markings, manufacturers may use unique trade names such as Iridium®, Ruthenium®, NuviTru™ etcto denote particular alloys or platings used in their products. These created marls represent both quality assurance standards AND brand recognition simultaneously so its important for buyers to recognize established brands before purchasing any items online or offline.
