The Welsh patron saint of friendship and love, Dwynwen fell in love with a young man named Maelon. She was unable to marry him due to her father's refusal and prayed to forget her love for him. Three wishes were granted to Dwynwen by an Angel who visited her in a dream and are in turn represented in the interlocking rose gold elements in this beautiful collection. The first wish restored her love, the second wish requested the hopes and dreams of true lovers to be met and the third wish was to devote the rest of her life in thanks for all she had been granted. The Angel also gave Dwynwen a potion to forget past hurt, symbolised here by the shimmering opal at the centre of each beautifully handcrafted piece. This beautiful silver and rose gold Dwynwen pendant measures 14mm wide. Contained within the pendant is rare Welsh gold, the very same gold as used by British Royalty since 1911. It hangs freely on a 46cm (18") silver curb chain. Matching items are available.

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.

  "Beautiful pendant"
I bought this necklace at the Tower of London. Its absolutely beautiful! I love wearing it!
Ilonka| London| 13 Sep 2017
  "Beautiful and Elegant"
Such a beautiful necklace! The size of the pendant is perfect, looks very elegant.
Melissa| Wales| 13 Jul 2017
  "Chain issue"
Beautiful pendant we totally fell in love with it, but dissapointed with the chain. It was dented in a few sections where we believe it was due to the way it was packaged in the box. Maybe its been on the shelf for a long time causing the indentations. We phoned customer service & told it would be under the head office discretion if anything could be done. As it was a joint present for my 70th Birthday & our Silver Wedding Anniversary we could not be bothered with the stress. We purchased another silver chain from a jewellers which actually beautified the pendant more!

  "Lovely but dainty pendant"
This pendant arrived in very good time and was well-packaged. It is beautifully crafted and pretty to look at, just a tad smaller than anticipated. Very pleased with the service.
  "Beautiful "
Beautiful necklace. Bought for my mums 60th birthday
Brian Le Bourvellec| Scotland| 10 Jan 2017
  "For my mum"
I brought this necklace on behalf of my dad, he wanted it to give to mum at Christmas, as she is from north Wales and is Welsh speaking. It came in a lovely presentation box with some history about the Welsh gold, but it is a shame that it did not come with the write up about the necklace, (Dwynwen) as it was a lovely story which my dad liked as well.
Helen deacon| staffordshire| 29 Dec 2016

My mother is Welsh and her birth stone is an opal, it was the most perfect present to give her, it was easy to order and came beautifully presented and she has not taken it off since receiving it.
Carol | Lincoln| 08 Dec 2016
This beautiful pendant was bought for my birthday as opal is my birthstone. The quality is excellent and the story behind the design is quite romantic. Delivery was very fast and the presentation boxes are beautiful and strong. Thank you.

Item is most excellently crafted and looks exactly as it does on website and the price is competitive, however would spend extra and get total gold if I could,thankfully my lady also likes silver
Matt Oliver| Oxford| 08 Nov 2016
  "Excellent Quality"
This is the second time Ive ordered from here. Birthday gifts for the partner get increasingly problematic, especially last minute. This is a good choice. Next day delivery and quality jewellery, in an affordable gift range, earn multiple brownie points.

A very pretty pendant on a clever chain.

  "Dwynwen Pendant"
I recently purchased this item and although I was pleased with it when it arrived I found it to be in an knot which took some time to unravel and risked damage. Also one reason I bought this particular item was the story that went with the piece and I was disappointed that this was not included in the paperwork. S.Willoughby
Scott Willoughby| Winchester| 27 Feb 2016

Extremely pleased with design and the colours in the Opal.
DMMorris| Aylesford, Kent| 11 Feb 2016
I am so delighted with my purchase, the necklace is beautiful and a timeless piece of jewellery that I shall treasure for ever.
Sue Wanklin| Wiltshire| 09 Feb 2016
  "Original and pretty"
I had not purchased from Clogau before but was attracted to this piece for the intricacy and delicacy of the design, the mix of silver and rose gold tones and the little opal. It conveys a slightly other-worldly quality it conveys, with the story woven into the design. I enjoy wearing it and it is also very versatile, as it goes with many things.
Helen| London| 27 Jan 2016
  "Christmas present for my wife"
I purchased the Dwynwen Pendant for my wifes main Christmas present and she is absolutely delighted with it. The sales person on the phone was very polite and helpful. When the pendant arrived it was very well packaged and came in a lovely box with complimentary care products. The pendant itself is stunning and the overall service was excellent. I will most certainly be buying from Clogau again.
Daniel| Newbury| 03 Jan 2016
  "Gorgeous necklace"
Love the necklace, smaller then I had thought it would be but lovely and great quality.
Helen| Scarborough| 01 Jan 2016
  "Christmas Present"
My wife was really pleased with the Dwynwen Opal Pendant, bought as a Christmas present. We have admired the Clogau range for years but this was my first purchase, I am sure it wont be the last. Best wishes for the New Year, Kenneth and Sharon Ritchie.
Kenneth Ritchie| Fraserburgh| 29 Dec 2015
I love my new necklace, it is delicate and very comfortable to wear. I love the history of the description and the opal. My only quibble is the length of the extension chain, which is very long and ruins the look of the delicate chain that comes with this necklace.
Sarah| Hampshire| 09 Dec 2015
  " Excellent quality"
The Dwynwen Opal Pendant, is a very rare pendant to find. Other companies didn't have it in stock, Clogau did! Excellent quality and craftsmanship.
Marc| Staffordshire| 01 Dec 2015
  "it will be the star in her Christmas stocking..."
My wife of almost 49 years has a number of Clogau pieces - both earrings and pendants - and she loves opals. This is a marriage made in heaven and it will be the star in her Christmas stocking.
PPA| mid-Wales| 29 Nov 2015
  "21st Birthday present"
My daughter loves her pendant which I got her for her 21st Birthday. All the more special as her Birth stone is the same as the Opal drop stone contained in the pendant.
Trevor| Northern Ireland| 20 Nov 2015
  "wife loved it"
top quality workmanship , the wife loved it , quick delivery as always
Bruce Smith| Northamptonshire| 13 Nov 2015
  "21st Birthday Gift"
Ive had a number of items from you spread out over a few years. Your service is impeccable and the quality of your jewellery is outstanding. It is very rare these days to find a company like your own that seems to have a work ethic that puts your customers first and sets a standard of workmanship thats second to none. All my purchases have been gifts for other people (family mostly, we have welsh roots) so they been chosen with love and care, given with love and care and I truly believe it when I say that they seem to have been made with love and exceptional care. Thank you.
Gill Hudson| York| 07 Nov 2015
  "Very good service"
Very good service, thank you.
Martin| South west| 05 May 2015
  "Lovely pendant!"
Bought this as a present for my daughters 21st birthday. Lovely and delicate pendant, slightly smaller than I expected but still very beautiful. Im sure she will love it! Great service , item arrived within 3 days, ordered on a Friday, delivered the following Tuesday.
Karen Thorley| Cheshire| 30 Mar 2015
  "Beautiful Necklace"
My wife had admired this on the Clogau website, so I bought it along with the earrings for her Birthday in April. It is actually as beautiful as it looks online. It was a little smaller than I expected, but it looks very delicate. She has an opal ring that she wears on special occasions so it will go with it.
Dave James| Southam| 20 Feb 2015
As usual the quality is of a very high standard. However I was disappointed with the delivery time, having to chase the order up. I placed my order on 5th February in time for a delivery well before Valentines day. I had no communication to say there was a delay and had to call customer services for an update as there were no emails stating when it was dispatched. As it happens it arrived the day before Valentines day, allowing no tolerance for any other delay. I would have expected it to be a little quicker however I am happy with the item and would return.

  "Wife loved them"
My wife is welsh and had always spoke about welsh gold, so when i was looking for a birthday present i checked out this site and loved the OPAL PENDANT and when i saw the earrings to match it was a easy choice to make. My wife just loved them. I ordered it on the 7th Jan 2015 to arrive on the 9th Jan and it was on time and in a great looking box with certs which just added to the overall moment for me to hand over. Will be looking in the future for other nice pieces to match. well done to all the staff.
  "Product was produced to exacting standards and simply another piece of jewellery my wife loves"
Well its Christmas and what to buy the wife! Well, just ask and you get an answer? "Id love a Clogau gold pendant, but dont want it too big and ho yeh can I have it in a mix of gold/silver". Mission set I visited several local jewellers. Unfortunately they didnt have what I was after or they didnt sell Welsh Gold. So, I searched the Internet and stating the obvious I went direct to Clogau gold site - hey presto - Placed the order and received excellent customer service and when the item arrived - simply wow and the bonus was the opal was my wives birth stone. Product was produced to exacting standards and simply another piece of jewellery my wife loves and wears with joy. Thanks Clogau team for delivering again - I couldnt have gone wrong really (lol) Thank you :-)

  "Absolutely beautiful"
This delicate little pendant arrived this morning and is absolutely beautiful. I purchased the pendant as a 30th birthday present for one of my daughters and Im sure shes going to be delighted. Clogau jewellery is always an investment for the future.
Deborah | Newport| 24 Dec 2014
  "Stunning piece of jewellry"
Id seen this first in the main Clogau shop in Cardiff but couldnt purchase it as the intended receiver was there with me at the time. I decided to buy it on line and am delighted with the quality and design of the pendant, set off by a perfect opal.
Joe| OBrien| 12 Dec 2014

  "More than I hoped for"
Being Welsh but having to live here in England I so miss home. My other half bought me this pendant for my birthday as opal is my birthstone. This is a stunning piece of jewellery which will be worn regularly I am so happy with it Diolch yn fawr
Teresa| Cambridgeshire| 03 Oct 2014
  "Very impressed"
I bought this for my daughter ready for Christmas (at her asking) and when it arrived was very impressed by the pendant. She will be over the moon with it. It is beautifully made, very artistic and the inclusion of the opal (which is her birthstone) makes it special for her. The ordering was easy (over the internet) and the delivery excellent. Cannot fault anything.
