Embedded within our vertically integrated workflow — reinforcing repeatability at every stage.
Each stone is examined under microscope to verify clarity, quality, and visual consistency before batching and calibration.
Dimensional tolerances are applied to each parcel, ensuring uniformity in diameter and depth across the batch.
Stones are grouped by defined calibration parameters — size, colour, and clarity — for structured, documented supply.
Touch Stone works exclusively with trade partners. Whether the requirement is calibrated melee, defined size ranges, or larger certified stones, we welcome structured enquiries aligned with production needs.
Larger certified stones and custom parcels are available upon request for established trade relationships.
