Product Detail
Blue Emerald Labradorite is a striking feldspar natural stone quarried in Madagascar, known for the iridescent blue flash — labradorescence — that moves across a grey, green and black base crossed with white web-like veining. For fabricators, wholesalers and project contractors, this page answers the purchasing question that matters most on this material: how to buy labradorite slabs wholesale without losing control of batch consistency between containers.
The Pain Point: Batch Drift Between Containers
Labradorescence is not a printed pattern. The intensity and angle of the blue iridescent flash, and the balance of the grey-green base against the black background, vary from block to block in every labradorite quarry. When a buyer orders several containers of Blue Emerald Labradorite slabs across a multi-phase project, and those containers are filled from uncoordinated stock, the result is a wall or lobby where one container looks intensely blue and the next looks muted and flat.
What this costs the buyer: slabs that photographed beautifully in the supplier's warehouse do not match what arrives at the jobsite. Fabricators are forced to re-select material on site, projects stall while replacement slabs are sourced, and the contractor absorbs selection labor and remobilization costs that were never in the bid. On engineered-look materials a mild mismatch can be hidden; on labradorite, where the iridescent flash is the entire reason the client chose the stone, batch drift is immediately visible and immediately disputed. Wholesale buyers who resell the material face the same problem one step further downstream — their own customers compare pallets from different deliveries.
Our Solution: Block-Locked Batches You Approve Before Loading
The solution to batch drift is not a better stone — it is a controlled supply process. Apexstone supplies Blue Emerald Labradorite slabs under a batch discipline built around three controls: grading, batch allocation, and photographic confirmation before shipment.
1. Every Block Is Graded A or B
Each labradorite block we process is graded into an A grade or a B grade according to the strength and uniformity of the labradorescent flash and the consistency of the base color across the slab face. Grade tags travel with the slabs through sawing, polishing and packing, so grade information never gets lost between the factory floor and the container. When you order, you buy a defined grade — not a lucky draw from mixed stock.
2. Containers Are Allocated From a Single Batch
For project orders, slabs are allocated from a locked batch of blocks rather than picked from open warehouse stock. If your order spans more than one container, the containers are filled from the same batch sequence and labeled by batch, so the material in container two matches container one. For buyers running a two-phase hotel or residential project, the second container can be reserved against the same batch allocation instead of being sourced months later from unrelated blocks.
3. You Approve Photos of the Actual Slabs Before Shipment
After polishing, the slabs allocated to your order are photographed and the photos are sent to you for confirmation before loading. What you approve is what ships. This single step removes the largest source of disputes in decorative stone importing: the gap between catalog images and physical containers. It also gives wholesale buyers documentation they can forward to their own project clients as part of the approval chain.
What This Means for Your Margin and Schedule
- Less site selection labor. Slabs arrive pre-graded and batch-matched, so your fabrication team sorts and books material against a numbering system instead of re-approving every pallet.
- Fewer rejected lots. Photo confirmation before loading moves the acceptance decision to the factory, where a mismatch costs a conversation instead of a container return.
- Phase-two continuity. Batch reservation means a follow-up order can be tied to the original allocation, protecting multi-phase projects from the visible mismatch that ends client relationships.
- Quote with confidence. A defined grade, defined thickness options and a 25–35 day production lead time let you put firm dates in your own quotation instead of hedging.

Choosing a Thickness
The 18 mm and 20 mm slabs are the standard choices for wall cladding and furniture tops where weight and cost per square meter matter. The 30 mm slab is the format most fabricators request for kitchen countertops and island tops, where edge build-up and structural depth are part of the fabrication plan. Because the iridescent flash varies in angle, larger slab formats up to 3000 x 1800 mm allow seamless full-height installations with fewer joints across the visible face.
Why the Physical Data Matters for Fabrication
Mohs 6 – 6.5 hardness sits in the range fabricators associate with granite-grade tooling rather than soft marbles, which affects saw blade selection, polishing sequence and edge profiling time. Water absorption below 0.5% and density of 2.7 – 2.8 g/cm³ are the figures project specifiers typically ask for when this stone is written into a schedule of finishes; both are documented here so you can answer spec questions without a second round of sampling.
Wholesale Terms for Buyers
Minimum order quantity is 50 m² (approx. 540 sq ft), which supports mid-size residential projects, boutique retail fit-outs and first trial orders from new wholesale partners. Standard production lead time is 25 – 35 days from order confirmation, with photo confirmation of your allocated slabs completed before the container is loaded. Slabs are packed in standard export fumigated wooden bundles with protective foam interleaving.
Purchasing FAQ
Can I get one consistent batch across several containers?
Yes — that is the core of our batch discipline. Slabs are allocated from a locked batch of blocks, containers are filled from the same batch sequence, and each container is labeled by batch. For multi-phase projects, tell us your phase schedule so the allocation can be reserved accordingly.
What is the difference between A grade and B grade?
Grading is based on the strength and uniformity of the blue iridescent flash and the consistency of the base color across the slab face. A grade slabs carry the strongest, most even labradorescence; B grade slabs are the same natural stone with softer or less uniform flash. Grade tags stay with the slabs through production and packing.
Do I have to buy the full 50 m² MOQ in one thickness?
The 50 m² (approx. 540 sq ft) minimum applies to the order. If your project mixes 18 mm cladding with 30 mm countertop slabs, confirm the split with us when ordering so the batch allocation and production schedule are planned correctly.
Can I see the actual slabs before shipment?
Yes. After polishing, the slabs allocated to your order are photographed and sent to you for confirmation before loading. Approval of these photos is the reference for what is loaded into the container.
What is the lead time and when does it start?
Standard production lead time is 25 – 35 days from order confirmation. Photo confirmation of allocated slabs is completed before loading; if your project has a hard installation date, share it at order stage so the schedule can be checked against it.
