About this Valuer

Sammantha Maclachlan FGA MJVA PJDIP CPAA is an Independent Jewellery Valuer based in Paisley and covers a large surrounding area within Greater Glasgow, Renfrewshire and Ayrshire. Her valuation fees are totally transparent and charged on per-item basis, a price quote is given for the appraisal assignment before any work begins.

Home Visit Service

Once an appointment has been set, Sammantha will visit you at your home, office, bank vault or some other suitable secure location. As all the gemmological, precious metal testing and photo equipment is portable, all of your precious items will be examined and appraised on-site. Your jewellery, watches, pearls and diamonds will not leave your sight while Sammantha assesses all the quality factors that are required to arrive at the correct value for your particular purpose. Additional research will be carried out off-site and your detailed appraisal and valuation report will follow in a few days time.

Valuations via Jewellers

This business also provides valuation services through retail jewellers. Farsighted jewellers recognise the benefits to their customers by bringing in a specialist valuer to perform assessments of their customers jewellery. Sammantha only works with respected and trusted jewellers. These jewellers very often hold "Valuation Days" where you can book a time-slot to meet Sammantha in their shop and have her inspect your items while you watch. Alternatively, if time is precious, you may prefer a drop your jewels into the shop and collect another day, along with your completed valuation.


Whilst Ms Maclachlan has a very rounded and broad knowledge of jewellery, including past experience in jewellery repair and restoration, there are some areas in which she excels.

Luxury brand watches - The authentication, appraisal and valuation of collectable modern and vintage watches is now a specialised area of the valuation profession. Watch brands such as Rolex, Patek Philippe, Audemars Piguet and Omega can attract extremely high values by virtue of a seemingly small detail being present or absent. Sammantha is regularly consulted by fellow professionals on these matters.

Diamond Grading - Ms Maclachlan is a trained Diamond Grader after studying at the International Gemological Institute in Antwerp. Where appropriate, the appraisal of your diamond will also include a plot diagram showing the internal features of your diamond.

Professional and Reassuring

I have never had my jewellery valued before (or properly insured) which only meant that I refused to wear any of my lovely pieces for fear of losing them. As most of them were gifts I had no idea of the value but each item had a lot of sentimental attachment to them. (I know it's silly but I didn't even know for sure if they were genuine gems!) Sammantha took the time to discuss each item and the written report, which I received within 24 hours, was very detailed. Sammantha reminded me that I should enjoy the jewellery I have been lucky enough to receive! Now that they are all properly insured, I can!

Expertise / Items Examined: Diamond necklaces, diamond earrings and a vintage watch.

Company Response:Thank you so much for the lovely review. It was a pleasure to meet you. You have such beautiful pieces and I am so glad you will be able to wear them and enjoy them now as intended.

Professional Valuation

With food banks etc I felt really guilty paying a vulgar amount of money for a 46th wedding anniversary gift for my wife from the Internet, on receiving it I thought it would be prudent to confirm value to ensure I really did get what I paid for. I needed same day valuation as there was a seven day time limit to return. I can highly recommend this professional and prompt valuation service no leaving goods for 3 days etc.

Expertise / Items Examined: 3 strand pearls with diamond clasp

Jewellery Valuation

Excellent service experienced! Took my diamond rings to be valued by Sammantha for insurance purposes. Valuations were carried out in-house without the need for any items to be retained or sent away so was so very convenient. Valuations took less than an hour and I received the paperwork less than 24 hours later. Rings were also cleaned! All round excellent experience and service would highly recommend!

Expertise / Items Examined: Engagement ring and an eternity ring.

Great Experience and Service.

I went to Sammantha with a bracelet to be valued for insurance purposes and ended up going again with more family jewellery. Her knowledge and enjoyment of the process was clear to see and made for a great experience. Sharing her knowledge was very interesting and hearing more about the items that have been in the family was amazing. Sammantha also showed genuine excitement at some of the more unusual pieces which was such a nice feeling, to see someone enjoy your family history.

Sammantha is highly recommended. A truly enjoyable experience and a fast efficient service with items being examined infront of you and reports sent to you within a day. I will definitely be recommending her!

Expertise / Items Examined: Gold bracelet and a gold and diamond bracelet.

From the first contact through text to telephone conversations around my initial enquiry, Sammantha was reassuring and extreme helpful. A face to face appointment was made to have Jewellery that had been left to the family appraised. All costs to be incurred were discussed beforehand, the appraisal was completed in under an hour and written appraisal received before I had expected to receive it. Highly recommended for your jewellery needs.

Expertise / Items Examined: Rings, Chains, Bracelet and Earings.

Company Response:Thank you so much for your lovely review Brian. It was a pleasure to meet you and I look forward to seeing you again.

Excellent Service

Excellent service from Sammantha. I really liked the fact that she did the review herself. A lot of places need to send your jewellery away but Sammantha does it in front of you there and then. She explained and reassured me about a diamond I had bought at an auction. Very knowledgeable and quick turn around. Will definitely use her again if I need anything else appraised and recommend.

Expertise / Items Examined: Diamond ring.

Company Response:Thank you so much Tracy for your kind words and recommendation. It was a pleasure to meet you and I look forward to seeing you again in the future.

Professional & Efficient

I have a number of items that I purchased throughout the years and had never had them valued since I bought them. Sammantha explained to me the importance of having my items valued and insured correctly. Sammantha made me feel at ease and answered all of my questions. I was pleasantly surprised by the valuation on return of my items, which only took a few days to be completed. The valuation was beautifully presented to me, along with my cleaned jewellery. It looked fantastic. I couldn't have been happier with the service. Thank you Sammantha.

Expertise / Items Examined: A pendant, ring, bracelet and earrings.

Great Service

Sammantha has valued all my watches and jewellery (15+ items) as the insurance company requests a new one every 2 years. I was delighted with the values given, the schedule has lots of photos and is very detailed. I strongly recommend anyone to use her services as she was very friendly, incredibly knowledgeable and very efficient. I’ll see you in 2 years! Thank you!

Expertise / Items Examined: All my jewellery and watches.
