I've always found everyone really helpful and the service fast and efficient. I've needed guidance on a couple of occasions and every time the person I've spoken to has been brilliant.

I have had a registered sponsors mark for around 55 years plus. I have always found the service to be first rate. In fact, it is also the preferred choice my many of my contacts within the working jeweller trade. The staff are very helpful too. Thankyou Sheffield.

We have been using the Sheffield Assay office for some 20 years now and that's testament to the fact that we have always been given a first class service by Ashley, Danny and the team. Very dependable and reasonably priced. Highly recommended.

I contacted the Sheffield Assay Office to ask for some help with my JET Diploma course with the hallmarking module and asked them for information in regards to the Bradbury’s book of hallmarks.

I spoke to Ashley Carson, the Assay Master/Chief Executive who was more than helpful and went above and beyond my enquiry. He has over 40 years of experience and certainly knows his stuff.
It was thanks to his fantastic support I decided I will be visiting the Sheffield Assay office to attend one of their tours once they are reopen from lockdown restrictions.
Thank you very much again!!
5 stars!!!

If everyone was as friendly, kind and efficient as Ashley Carson, the world would certainly be a better place.

Less than a week since I raised a hallmarking query, my beautiful ring has been hallmarked and returned to me. The service received has been brilliant all round, definitely above and beyond what I expected.
Thank you Ashley for your excellent and speedy service. Super work!

I just wanted to say thank you. I dropped my last Christmas commission in on Monday 12th December, thoroughly expecting it to take 5-7 working days considering the time of year, and how everyone seems to be ill at the moment. I got a text to say that it was ready to collect 3.5 days later. I regularly see my jewellery colleagues in online forums complaining about the service, accessibility and sometimes quality at London (and occasionally Birmingham), so it’s brilliant to receive such fab service from you. Just thought I’d say- please share my thanks with the team.

We always look forward to phoning Sheffield Assay Office as we know we will be greeted by someone friendly, knowledgeable and positive. We think these are great attributes especially during recent months when it has been tough in the industry.
All at Mark Milton
The team at SAO are just incredible, to mention just a few: Andy, Danny and Chloe. They are always super helpful, accommodating and organised.
From start to finish the operation runs smoothly and we are very happy with the assaying/hallmarking processes, we could not fault the service and long may it continue.

I wanted to email you to express how delighted I am with your teams extra service.

We had a parcel sent to you on Wednesday via royal mail but it didn't arrive with you until today. One of the rings inside the parcel was for a client that is leaving for Monaco tonight to propose whilst away (he left it late!).
Our client is due to pick up the ring from us this afternoon. After chatting to Andy in progress, he acted instantly and had the ring in his hand and said it would be marked by 2pm. Brilliant!
We were then going to arrange a bike to collect it but after speaking to our delightful client it just so happened to be just north of Sheffield, so would be passing you on route to us. Another quick call to Andy and arranged for our client to pick the ring mount up from you (with passport ID and at our risk), and bring it to us.
I emailed progress with all his contact details and told my client to get to you for 2pm. I then received a reply form Chloe asking me to tell my client to ask for her at the counter. Then to my surprise I got another email form Chloe an hour later saying my client had collected the ring. The client has sat with my setter watching his ring being made and has just left with a huge smile on his face!
If only all service in our trade was as slick as this. This exceeds everything I have experienced in 18 years in the trade. The jewellery trade is slow at the moment as we all know and for our key supplier and client to work with us like this is simply amazing.
This is an £8k sale. You team didn't even know the value, it could have been £500, but they acted like I was the only client you have.
Hats off to Chloe and Andy. Absolutely amazing and they deserve a huge pat on the back!

Handcrafted from vintage or antique hallmarked solid silver spoons dating from the 1700s to the 1960s, each of our pieces is lovingly handcrafted at our workshop in North Wales.

Jaspersparkle silver spoon rings each have their original historic hallmark visible, we are very proud to be able to give the silver spoons a new lease of life, honouring tradition and giving the customer a unique handmade piece.
Each item is then authorised by the Sheffield Assay Office to ensure we are working to the requirements of the Hallmarking Act.
We have submitted over 250 unique articles to the Sheffield Assay Office this year, for Change of Use authorisation. Thank you so much for your efforts this year. The latest batch of silver and certificates arrived this morning and we're so pleased with the work. Thank you, it's lovely to have the hallmarks identified and even the weight added to the certificates.

Sheffield Assay Office has been a great support for us in recent weeks and the staff at your facility have been very collaborative and a pleasure to deal with as usual.

We are re-launching a key product range to our business, Calgitrol(r), which is a medical device product used in the treatment of chronic wounds for very ill patients. Through the re-launch of this product range we have to re-validate the processes of which there are 3 product categories Askina(r) Calgitrol(r) Ag, Askina(r) Calgitrol(r) THIN and Askina(r) Calgitrol(r) Paste.
The key advantage of the product range in the marketplace is it's ionic silver alginate matrix which provides for broad anti-microbial effectiveness and helps prevent contamination from external bacteria.
To this end how Sheffield Assay support us is in testing our products for levels of a key ingredient, silver, in our manufacturing processes. With your prompt turnaround on testing it has supported us in completing process validations and initiating sterilization validations (3 batches of 51 samples per batch for all 3 products in the range). Meeting our site timelines further supports us in submissions for regulatory review.
We look forward to a continuation of a great working relationship and to keeping you busy in the coming months.
