Jewellery Metals - All You Need To Know!

What Type Of Jewellery Should I Choose On My Wedding Day?

Quality of jewellery materials is incredibly important to The Bold One Co. Let's delve into the metals that serve the backbone of our jewellery craftsmanship and the unique qualities and significance these metals bring to our treasured pieces.

Solid 9K Gold

  • A popular & traditional choice for jewellery.
  • The purity of gold is measured in karats(K), with 24K being the purest form.
  • Pure gold is too soft for most jewellery so it is often alloyed with other metals like silver, copper or zinc to increase its strength and durability.
  • 9K gold has a paler gold colour compared to higher karat gold.
  • Genuine 9K gold jewellery will have '9K' or '375' stamped on the piece.

14K Gold

  • In solid 14K gold, 14 out of 24 parts of the alloy is pure gold & the remaining parts are made up of other metals such as copper, silver or zinc.The addition of other metals is to increase the strength & durability of the gold since pure gold is relatively soft.
  • 14K gold is a popular choice due to its balance between purity & strength.
  • Offers a higher gold content compared to lower karat alloys whilst maintaining good durability & providing a more affordable option compared to higher karat gold such as 18Kor 24K.

14K Gold Filled

  • 14K Gold Filled consists of a layer of 14 Karat gold mechanically bonded to a base metal i.e jeweller's brass.
  • A popular alternative to solid gold due to its durability & affordability.
  • The process of creating 14ct gold filled jewellery involves heat & pressure bonding which results in a thicker layer of gold.
  • The gold layer in 14ct gold filled is at least 5% of the total weight of the item, making it significantly thicker and more resistant to wear & tarnish compared to gold-plated jewellery

22K Gold Vermeil

  • Gold Vermeil is a type of gold plating that refers to a layer of gold applied over sterling silver.
  • To be considered vermeil , the gold layer must be at least 2.5micorns thick & consist of gold with a minimum purity of 10 Karats ensuring a higher quality & longer lasting gold-plated finish compared to standard plating.
  • Our 22K Gold Vermeil jewellery comes with a minimium of 3 microns of gold offering a luxurious appearance increased durability, resistance to wear & prolonged life of your jewellery.

Sterling Silver

  • Versatile metal used in jewellery making.
  • Lustrous & affordable in comparison to other precious metals.
  • 925 is the most common type used in jewellery.Consisting of 92.5% silver & 7.5% of other metals for added strength.
  • If jewellery is genuine 925 sterling silver you will see a small 925 hallmark stamped on the jewellery.You will see this hallmark on all of our sterling silver jewellery assuring you the item meets the global standard & is of high quality.

24K Gold Plated

  • 24K gold plated refers to jewellery which has a thin layer of 24K gold electroplated or mechanically bonded onto the surface base metal. We use jeweller's brass as the base metal in our 24K gold plated items.
  • The term "24k" indicates the gold used in the plating process is pure without any additional materials mixed in.
  • 24K gold plating can wear off over time with regular use and exposure to moisture, chemicals & friction. We use 3 microns of gold plating ensuring higher durability than standard plated items


  • Popular for wedding bands,engagement rings and other fine jewellery.
  • Considered high end & often more expensive than Gold or Silver.
  • Platnium is a dense, rare & durable metal.
  • Naturally white in colour and is highly resistant to tarnish & corrosion.
