Quality Built into Every Stone
Quality begins before the first cut and continues through every step: block selection, edge cutting, finishing, packing, and loading. Each stage is monitored by trained teams, supported by check sheets, and guided by customer-approved plans to ensure dimensional accuracy, finish consistency, and customer-specific compliance.

Quality is a Process, Not a Checkpoint
Natural stone has character, variation, and depth. Our responsibility is to understand these aspects, identify irregularities early, and process each stone with accuracy and care. This lets us produce material that is visually refined and technically aligned with the intended application.
STEP 1
Raw Block Selection
Before production, blocks are inspected for suitability, visible damage, colour character, and production viability. Only approved blocks are taken forward for primary cutting.
STEP 2
Slicing and Primary Inspection
The cutter slices the block to the standard thickness or the customer’s specifications. Operators monitor the process to ensure dimensional accuracy and maintain a ±2 mm thickness tolerance.
STEP 3
Natural Defect Segregation
The cut stone slabs are inspected for natural defects not visible at the block stage. This includes pits, holes, tapering, colour lines, cracks, and other stone-specific characteristics. Usable material moves ahead, while rejected material is segregated.
STEP 4
Edge Cutting and Sizing
Approved material moves to edge cutting, where it is cut as per plan. Our teams check sizing, right angle, thickness, and dimensional accuracy during the process.
STEP 5
Surface Finishing
Finishes such as honed, sanded, desert, blaze, etc. are processed according to the requirements. The finishing route varies depending on the finish specified in the order.
STEP 7
In-Process Quality Checks
Throughout secondary processing, QC teams conduct random and stage-wise checks to verify finish quality, including texture, smoothness, surface feel, and slip resistance, as well as size accuracy and overall appearance.
STEP 6
Final Inspection
Before dispatch, the completed order is inspected again for size, thickness, right angle, finish, visible defects, and colour consistency. Rejected pieces are removed and replaced where required.
STEP 7
Secure Packing and Loading Handover
Material is packed as per the plan, crate type, weight requirement, and destination needs. Final packed crates are handed over for loading only after quality approval.

Produced to Plan. Checked to Specification.
Every order is processed according to approved production plans. These plans guide size requirements, finish selection, quantity, crate planning, weight limits, and loading schedules.
Whether the requirement is a specific thickness, a calibrated cut-to-size format, a brushed surface, a sanded finish, or a project-specific crate plan, our production and QC teams work together to ensure the final material conforms to the approved specification.
Documented Checks at Critical Stages
We use stage-wise check sheets that record size, accepted and rejected material, and reasons for rejection. This documentation helps identify defects early, reduce rework, and maintain accountability throughout production.
The most critical checkpoint is immediately after block slicing, when hidden natural characteristics first become visible. At this stage, trained QC personnel inspect and segregate material before it moves to edge cutting and finishing.
Checked, Packed, and Ready for Transit
Before leaving the facility, material goes through final review and crate planning. Products are packed with protective materials and organised according to customer requirements, crate type, weight limits, and loading plans.
This final step confirms approved material is securely packed, clearly identified, and ready for safe transit.
Promise Beyond Stone
For us, quality is discipline at every stage. It is the careful selection of raw blocks, accuracy of every cut, the trained eye that identifies natural variation, the skilled hand that checks a finish, and the final review before dispatch.
By choosing Stonestry, you choose natural stone created by experience, controlled by process, and delivered with accountability.
