In Conversation with Jason, a Gemstone Trader


In this interview, Jason, a second-generation gemstone trader, shares his journey into the world of gemstones, inspired by his father, a gemmologist and trader since the early 1960s. He reflects on how the industry has evolved, current market trends, and the importance of ethical sourcing.

Introduced by Lucy Crowther, founder of Minka Jewels, this Q&A highlights the expertise and passion behind the stones that shape her collections, offering a rare glimpse into the journey from mine to masterpiece.

1.  Can you tell us a bit about how you got into the gemstone trade? Was there a particular person or experience that inspired you to pursue gemstone dealing?

I had always had an interest in the beautiful things my father brought home. He was a Gemmologist and gem trader since the early 1960’s. I joined the business directly from college and learnt from him and his team how to deal in gemstones. I watched them buy, sell and grade gemstones and learned everything I could from this. 

2. You obviously have a huge amount of knowledge and insight in the industry, what have you noticed over the years? Have you seen any significant changes within the market since you began?   

The market is always changing. Although there is always some demand for smaller commercial goods in the UK, it is much lower these days. Gem deposits are finite, so the market changes as mines are exhausted or new sources open. We have to be constantly ready to learn and adapt to this change. Trends currently are for attractive individual stones in less traditional colours such as Yellow and Green.

3. What challenges have you faced throughout your time as a gemstone dealer, whether it’s dealing with market volatility, lab-grown stones, logistics, or maintaining trust with clients? How have you overcome them?  

As coloured gemstone dealers, lab-grown stones (synthetics) have always been a factor; surprisingly lab grown Gems have existed for over 100 years. With good observational skills and training identifying these stones does not offer significant challenge to a qualified gemmologist. Training and product knowledge are key here. Our knowledge, experience and relationships help us to support clients’ expectations. The UK is not a gem producing country so these key relationships with trusted suppliers are worldwide. They help us to maintain supply chain and product integrity and thus our client’s trust. Integrity in the product is everything.

4. How do you typically buy your gemstones? Where do you mainly travel to? How do you go about ensuring traceability and ethical practices throughout your supply chains? What factors do you consider when selecting suppliers? 

Different gemstones are sourced in different ways. It would seem logical that visiting a mine directly would be the most economical way to trade. This is not usually the case. Multiple mines and mining areas feed rough material into a market trading town. The cutting and polishing are often done elsewhere. Thus choice, availability and pricing are often more competitive in the markets for polished goods than at the mine.

We have close relationships with cutters in Thailand, Brazil, India, Sri Lanka, Colombia and China, to name but a few. We do everything we can to ensure responsible practices with them and where possible we travel to their workshops to better understand their expertise. I have currently travelled to 101 countries since starting in the business and do not expect this to stop travelling anytime soon! 

5. What is your favourite gemstone and why? 

As an active gemstone trader / collector, my answer to this is always, ‘the next one’.  There is nothing better than seeing a recipient delight and engage in a gemstone that suits them perfectly. I prefer great examples of the more traditional gemstones; fine Sapphires that are vibrant blue, true green Emeralds and Rubies with high lustre and good colour. These stones are all classics for a reason. Just yesterday I opened one of our Sapphire boxes and a cushion cut, blue Ceylon Sapphire shone out at me: simply beautiful.

6. What are the most important factors to look out for when buying a gemstone? 

I asked this very question of an old family friend a few years ago. Nonchalantly he replied, ‘Oh that’s easy colour lustre size shape cut’.  Colour is the primary factor, then look for an attractive appearance. This means balancing the cut size and shape that appeals to you. With these factors you won’t go far wrong. 

7. What trends have you seen over the last couple of years and in terms of market value and interest, is there a gemstone that we should be keeping an eye out for? 

There is a recent resurgence in interest in coloured gemstones and the aesthetic that they hold, coloured gemstones have always had trends that ebb and flow. Teal Sapphires and Yellow Sapphires have been popular over the last few years; this is somewhat fashion based but has held longer than many brief trends. Brand new gemstones coming to market (such as Paraiba Tourmaline) are uncommon. We may not see anything so distinctive again. When looking for a gemstone, take advice from people who see and handle a lot of stones. For me, quality is always the way to go. Find a gem or gemstones that you like that fits your budget and ask your jewellery professional for advice. 

8. What advice would you give to someone interested in entering the gemstone trade - either as a dealer, gemmologist or collector? Are there any important lessons you have learned over your time?

It’s a field you must be interested in, start off slowly, learn and develop relationships in the trade. It is a close community often perceived as secretive, this is not generally the case, the trade must be discreet by its nature so it can take time to understand the nuances. Once they know you are genuine, most traders will happily share their knowledge. I am learning new things from industry peers every day. 

Whether you're new to gemstones or a seasoned collector, Jason’s insights offer a deeper appreciation for the craft, expertise, and care behind each stone.
