This concept organises an enquiry and information exchange. CARAT is not currently processing orders, deposits, escrow or transactions.
Built in stages.
Released with care.
The roadmap remains intentionally focused: understand the market, shape the right workflows, then introduce CARAT through a controlled launch.
Refining the buyer and seller experience, stone records and marketplace boundaries.
In developmentTesting core journeys and gathering informed feedback before broader access.
Planned phaseIntroducing the first considered version when the experience and operating model are ready.
Target windowDates and scope may change as the platform develops. CARAT remains a product in development by the team at Modulo.
Technology opens the door. Expertise still decides.
Every important gemstone decision involves judgement, documentation and conversation. CARAT is intended to organise the beginning of that process—not pretend to replace it.
