Diamantina Quartz: A Wholesale Buyer's Guide for Crystal and Mineral Shops
Share
Quartz is the backbone of most crystal shops. It sells to collectors, to metaphysical customers, and to people who simply want something beautiful on a shelf. But wholesale quartz is usually sold in flats chosen by someone else, often with no locality at all. This guide covers the quartz crystals and minerals we carry from Diamantina, Brazil: where they come from, what each type looks like, how to care for them, and how to build an order around them.
Where Diamantina quartz comes from
Diamantina is a colonial-era mining town in the state of Minas Gerais, Brazil. It grew up in the 1700s around one of the world's great diamond rushes, which is where the name comes from. The town sits in the Serra do Espinhaço, a long mountain range built largely of quartzite.
Quartz crystals grow in veins and pockets within that rock. They are still worked by small operations, often by hand. Every Brazil lot we carry comes from a single family-run operation near Diamantina. We buy from them directly, with no importer in between.
Because each pocket is different, color, clarity, and crystal habit change from one opening to the next. That's why we film every lot rather than describing material in general terms. What you see in the video is the material that ships.
The types in our Brazil collection
Lemurian quartz. Long, clear to milky points with fine horizontal ridges running across the prism faces. Collectors and metaphysical buyers look for those ridges by name. "Lemurian" is a trade name from crystal lore, not a separate mineral; it is quartz with a distinctive growth pattern. We carry it as single points, as cabinet clusters, and in pink, silver-toned, and tangerine colorways.
Tangerine Lemurian. The rarest Lemurian color. The orange tone is usually attributed to a thin natural coating of iron oxide on the crystal surface.
Cathedral quartz. Points built up from many smaller terminations stacked along the body, so the crystal looks like a cluster of spires. Each one has its own architecture, which makes it a strong single-piece seller.
Diamantina quartz clusters. Groups of points growing from a shared base, from small hand-size pieces to display clusters. Clusters are the easiest shelf centerpiece in any shop.
Golden healer quartz. Quartz with a natural golden-yellow tone from iron-oxide staining. Ours are polished points.
Rutilated quartz. Clear quartz threaded with fine golden needles of rutile, a titanium mineral. Dense rutile is what sets the value, and it photographs beautifully under a shop light.
Sang du Coeur. French for "blood of the heart," and also sold in the trade as blood citrine. It is quartz carrying deep red to orange inclusions inside the crystal.
Hematite rose. Hematite, an iron oxide, crystallized in rosettes of thin blades that open like petals. These are small pieces, sold by count rather than weight.
Care and display
Quartz is hard, about 7 on the Mohs scale, so it handles everyday display well. The weak point is the termination. Tips chip when points knock against each other, so store and ship them wrapped individually.
Color that sits on the surface needs gentler handling. Tangerine and golden healer quartz get their color from iron oxide. Never soak them in rust removers or acid cleaners, which strip that color away. A soft dry brush is enough. Uncoated clear quartz can be rinsed in plain water.
As a general precaution, keep colored quartz out of strong direct sun in a window display. Clusters do best as centerpieces at eye level. Single points sell well near the register, where customers can pick them up.
How to order
Every lot is sold whole, exactly as filmed, with its piece count, total weight, and per-kilo rate on the page. New to buying this way? Our guide to buying mineral lots by the kilo explains how to read a lot and size it to your shop floor.
The order minimum is $200, and it applies to your cart total. You can mix lots across any origin to reach it. A few Brazil lots clear the minimum on their own; most pair well with a second lot. Quartz pairs especially well with our Indian zeolites, which bring color and texture that quartz doesn't.
Pricing is public, and you don't need an account to see it. If you hold a resale certificate, upload it at checkout or in advance and it will apply to your order. Want a closer look at a lot before buying? Request more video and we'll film it for you.
