Every piece of Clogau jewellery contains Welsh gold

Welsh gold is one of the rarest and most sought-after golds in the world

Clogau Welsh gold is undoubtedly one of the rarest in the world. Due to the cost of extracting it, Welsh gold is no longer being mined and the remaining supplies are becoming increasing sought-after. Each piece of Clogau contains rare Welsh gold from the Clogau St. David’s Gold Mine in Bontddu (pronounced “bont-thee”), in Snowdonia, North Wales. In 1923 this mine was famously chosen to supply the gold that has been used to create generations of Royal Family wedding rings. Clogau jewellery gives you a piece of this wonderful and unique heritage with every piece.

Welsh gold is worn by Royalty

Since 1923 the Royal family have been wearing wedding rings made from pure Welsh gold. This tradition was founded by The Queen Mother, then Lady Elizabeth Bowes-Lyon, on her marriage to the Duke of York on 26th April, and continues to this day with the Duchess of Cambridge.

Other members of the Royal family that have worn Welsh gold rings include Her Majesty the Queen, Diana Princess of Wales, Her Highness Princess Margaret Countess of Snowdon, and Their Royal Highnesses Prince Charles and The Duchess of Cornwall.

Welsh gold stamp

We stamp every piece of jewellery, size permitting, with the Clogau logo and Welsh Dragon. The Welsh Dragon stamp indicates that Welsh gold from the Clogau St. David’s Gold Mine in Bontddu, Snowdonia, is included in your piece.

There are other marks that you will find on your jewellery including our sponsor’s mark (the “CG”), the standard mark which indicates the type of fineness of the precious metal and Edinburgh castle, the symbol of the Edinburgh Assay Office.

Stamps applied by Clogau including Welsh Dragon


Certificate of Authenticity

We guarantee that your Clogau jewellery contains rare Clogau Welsh gold extracted from the Clogau St. David's Gold Mine in the heart of Snowdonia, North Wales, once owned by the company.

The Clogau gold mine is situated in one of the most stunning parts of Wales, deep in the heart of Snowdonia. Interestingly, it first opened as a copper mine in 1842 and it wasn't until 1854 that gold was accidentally discovered there.

The Clogau St. David's Gold Mine has gone through mixed fortunes over the last century due to the veins of gold being very inconsistent and difficult to locate. This has made Clogau Welsh gold extremely rare.

i purchased a Clogau necklace fairly recently but found the chain to be a little too short, not wanting to spoil the look I looked on the Clogau web site and found an extension which now means I can wear my pendant. Thanks very much your jewellery is too special to have any old extension.
Nicki| Kent| 05 Jul 2017
This is great, I bought a necklace but it was only 16 inch and was too tight, found on the website and ordered this and is the correct length now.

  "Great Chain"
My partner bought me a chain for Christmas which was lovely, but I wanted it longer, so as the chain was bought from Clogau, I decided to buy the extension chain from them as well, this is a great little chain, it clips on simply and looks lovely, I would recommend it. It is chunkier than the original, but it still looks good, and I am very pleased with mine. I would recommend it to anyone.

  "So delighted"
I was bought a beautiful necklace from Clogau which was slightly small for my neck, I was delighted to find you sold an extender which came very quickly. So delighted to now be able to wear my beautiful necklace. Thank you.

  "Makes my lockets and pendants a far better length for me"
Well packaged and in good order. Thank you. Makes my lockets and pendants a far better length for me. Although its silver I can also use it on my white golds pendants. Good purchase.
Margaret Williams| West Midlands| 12 Jan 2017
Lovely item, would probably upgrade to gold and silver in the future.

Bought a Gold ring for my 60th birthday from Cardiff Store, have since purchased pendants and earings and a silver ring from Resorts World, Birmingham, staff are very knowledgeable and welcoming, products excellent quality.

  "Fast and excellent service "
I ordered the extender for a clogau fairy locket that my husband had bought for me as a birthday present. The chain was a tad short but this extender is the perfect solution. Its sturdy too so I have no fear of loosing my beautiful necklace.
Alexandra Dixon | Tyne & Wear| 05 May 2016
  "To make better use of pendants purchased"
Thought it a good idea to purchase the extender to ensure the Pendants purchased can be worn with different styles of clothing.

  "Beautiful Quality jewellery and has a nice story behind it too"
I love this bracelet I dont normally wear a lot of jewellery [ just a necklace] and whilst looking for a new necklace I came across the clogau website and wanted one of everything , so I ended up with this necklace and a charm bracelet and I love them both .The quality is excellent I love the whole range and from now on only want clogau jewellery. Beautiful Quality jewellery and has a nice story behind it too .I actually bought the bracelet from Birmingham clogau store and found the staff to be lovely and friendly though they dont hold much stock. I am looking forward to buying some charms and filling up my bracelet with their beautiful collection of charms. Love this jewellery and recommend it to anyone.

This extension chain is an excellent addition(and it is in its own pouch),I have always had to search for one in the past.

  "Well done Clogau."
I was given a silver Welsh dragon pendant as a gift from the Clogau shop in Betws y coed and I felt it was too short,ordered the extention chain on line now it fits exactly where I wanted it and the dragon pendant is really beautiful. I am now thinking of looking for a pair of earrings to match. Well done Clogau.
Ann | Gwynedd| 12 Nov 2015
  "Extension chain"
Bought to extend the chain length on a Cariad Heart pendant which my wife occasionally likes to wear lower. The extension is good quality and feels secure and does the job nicely.
