Touch Stone is a family-founded diamond house headquartered in Antwerp, built on four decades of experience in the trade.

We manage the work end to end. Our office in Mumbai issues the rough and checks every polished parcel, and stones are manufactured in our own RJC-certified unit in Surat. Every parcel we supply is selected, calibrated and documented before it reaches a client.

Structure is not a statement — it is the basis of reliability.
