Want to buy in bulk

Buy in volume. Build a supply relationship at source.

Finding a continuing supply of suitable gemstones takes more than finding a seller. You need access to material, someone who understands your requirements and a practical way to get the stones from East Africa to you.

We bring those parts together, so you can concentrate on cutting, designing, collecting or selling.

We supply individual stones, parcels and larger quantities, and welcome enquiries from buyers seeking an ongoing source of East African material. Tell us what you need, the quality you work with and the quantities you can buy, and we can discuss suitable opportunities.

Direct sourcing without building your own buying operation

We are fourth-generation gem dealers and have been selling gemstones online since 2002. Through our buying office in Arusha, Tanzania, we buy directly from small-scale artisanal miners and maintain sourcing relationships built over decades.

We speak local languages fluently, understand the realities of buying on the ground and work with miners through fair dealing and repeat business. Many of the mining operations we work with are family-run or involve people from the surrounding community.

These relationships often give us early access to newly mined material, sometimes within hours of recovery. We examine what is available and assess its quality and suitability before offering it to buyers.

You benefit from those relationships and our selection experience without having to travel to mining areas, establish your own supplier network or arrange the material’s export out of East Africa. Customer orders are dispatched from the UK.

Selected parcels and larger buying opportunities

We buy both singles and parcels, and material can become available in quantities that suit volume buyers. Discussing your requirements directly lets us consider opportunities beyond the individual pieces already listed on the website.

The kinds of opportunities described in our sourcing work include kilogram quantities of chrysoprase, heated tanzanite cabbing rough, smaller parcels of Mahenge or rhodolite garnet rough, and mixed-grade Winza sapphire parcels. These are examples of the types and scales of material we may encounter, not a statement of current availability.

Availability, grade, parcel size and price depend on what is being mined and offered at the time. We will discuss the actual material with you rather than promise a fixed supply of every gemstone.

Selection, grading and treatment information matter at every quantity

Buying a larger parcel should not mean overlooking its characteristics. We assess rough for colour, clarity, shape, inclusions and cutting potential, and consider cutting quality and polish when offering finished stones.

Tell us whether you need faceting rough, cabbing material, crystals or finished gemstones, and the quality range you can use. A mixed-grade parcel and a closely selected parcel serve different purposes; understanding your needs helps us discuss a suitable option.

We specialise in natural gemstones with full treatment disclosure. Natural does not automatically mean untreated, and treatment information is part of assessing the material and its value. Any assessment of rough’s potential after cutting is an informed opinion, not a guarantee of a particular finished result.

Our listed prices are open to everyone

We began by supplying dealers and resellers. Today, anyone can buy through our website at the listed prices without needing a trade account.

Our prices reflect direct buying and selection at source. For larger purchases or regular supply, contact us to discuss the material, quantities and pricing that may be possible. A bulk enquiry does not automatically mean a discount on every item; any proposal depends on the actual purchase.

Our price-match promise is described on our Our Prices page. If you would like us to consider a comparison, send the details before purchasing so we can confirm whether it qualifies.

Looking for regular supply?

We welcome buyers who purchase occasionally as well as businesses seeking an ongoing relationship. Long-term supply works best when we understand what you can use, how you buy and the price range that makes sense for your business.

Please send the gemstone types, intended use, preferred sizes, acceptable quality range, treatment requirements, quantities, budget and expected buying frequency. Include any links or examples that help explain what you are looking for.

We can then explore suitable material through our contacts and discuss available parcels, sourcing possibilities and next steps. Our aim is a mutually beneficial relationship, not simply a one-off sale.

Agree the details before purchasing

Before you commit, we will discuss the particular material, quantity, price, payment arrangements and shipping. We do not offer our own credit or deferred-payment terms. Please do not assume a particular third-party credit or instalment service will be available for your order.

We dispatch from the United Kingdom, with Royal Mail and FedEx delivery options. Shipping charges and delivery estimates depend on the order, destination and service; please confirm the applicable arrangements with us for a bulk purchase.

Direct access to East African gemstones. The sourcing work already done.

Buying gemstones from East Africa should not mean travelling to mining areas, finding reliable suppliers, sorting through mine-run material or arranging shipment out of Africa yourself.

We have already done that work for you.

We are fourth-generation gem dealers, serving buyers online since 2002. Through decades of direct relationships with small-scale miners, we find and select individual stones, assess their quality and potential, and bring them to you through our UK-based business.

You choose from selected material rather than sift through unselected miners’ lots. You can ask experienced gem dealers about the stone before buying. And your order is dispatched from the UK, without you having to organise its export from East Africa.

Whether you want one stone for a personal project or a regular supply for your business, you can buy at our website’s listed prices. You don’t need to travel to the mines, purchase a whole miner’s parcel or qualify for a trade account.

We find and select the material, so you don’t have to

Finding a seller is not the same as finding material worth buying. Miners’ lots can contain a wide range of qualities, and selecting suitable stones takes time, access and experience.

We examine material at source and select individual pieces for colour, clarity, brightness, character and suitability. For facet rough, we also consider shape, inclusions and the finished stone the material may produce.

That means you can spend your time choosing material for your project or collection, rather than searching through large quantities of mine-run material and trying to identify the promising pieces yourself.

Our selection includes facet rough, cut gemstones and selected rare and fine crystals. Each is offered for its own qualities, not simply because it happened to be part of a miner’s lot.

Our miner relationships give you access without the journey

Reliable access at source is built over years. We buy primarily from small-scale artisanal miners whom we have known personally for decades, through relationships based on fair dealing, mutual respect and repeat business.

We speak local languages fluently, understand the realities of working on the ground and maintain direct contact with the people producing the material. In some cases, these relationships also include practical guidance and support for mining activities.

Many of these operations are family-run or involve people from the surrounding village. Working with them means dealing with the people whose livelihoods depend on the material, not treating sourcing as an anonymous transaction.

Our longstanding buying relationships often give us an early opportunity to see newly mined stones, sometimes within hours of recovery. Miners bring material to us alongside the material we seek out.

You benefit from that access through our selection, without having to travel, establish those relationships yourself or navigate unfamiliar mining and buying networks.

We help you understand what you are buying

A photograph alone cannot explain everything about a gemstone. You need useful information about its characteristics and limitations to decide whether it is right for you.

We include weight, origin, treatment information and relevant characteristics in our listings. Inclusions and other limitations are part of the description, not details to hide.

Assessing facet rough requires particular experience. We consider its clarity, colour, shape and cutting potential, rather than judging only its surface appearance. Our assessments of cutting potential are informed opinions, not guarantees of a particular finished result.

For cut stones, we pay close attention to cutting quality and polish. Our listings distinguish native-cut material from precision-cut stones so you can assess each piece on its own merits.

If you need more information about clarity, treatment, sourcing, suitability or any available independent report, ask us before purchasing. You can discuss the actual material with us rather than make the decision alone.

Direct buying makes our listed prices accessible to everyone

We began by supplying the wholesale trade. Today, our website is open to jewellers, designers, gemstone dealers, retailers, hobbyists, collectors and first-time buyers alike.

We buy directly from miners and select material ourselves, reducing the number of buying and selling stages between the source and our customers. Our aim is to pass that value on while paying fair prices and maintaining lasting sourcing relationships.

You do not need a wholesale business or a trade account to access our website’s listed prices. The individual stone or lot you see is available to you, whether you are buying for yourself or for your business.

We believe in long-term customers and repeat business, not simply getting the highest possible price for a single sale.

We handle the sourcing and dispatch from the UK

Buying at source can also mean dealing with the practical challenge of getting material out of the region. With us, you do not have to organise that part of the process yourself.

We handle our sourcing and selection in East Africa and dispatch customer orders from the United Kingdom. You choose your material through our website rather than coordinate its journey from the mining area.

Royal Mail and FedEx shipping options are available. Check the applicable services and charges at checkout, and refer to our shipping policy for delivery information.

For international deliveries, any destination-country import requirements, duties or taxes are separate from the sourcing work described here.

Need something specific? We can ask at source.

You are not limited to asking whether a suitable stone happens to be listed today. If you need a particular gemstone or category of material, we can speak directly with our mining contacts and explore what is available.

Tell us the gemstone, size, quantity, quality, intended use and budget you have in mind. Availability depends on what is being mined and offered at the time, and we will discuss the possibilities with you.

Our selection changes as material arrives. Subscribe to our email updates for new additions, or contact us to discuss a particular requirement or ongoing supply relationship.

Whether you are choosing your first gemstone, cutting rough, designing jewellery or building a collection, our purpose is the same: to connect you with suitable East African material and make buying it more straightforward.

Decades at source. Individual selection. Clear information. UK dispatch.
That is the experience we bring to buying gemstones.
