Unrecorded terms create expensive disputes
Diamond transactions move faster than formal paperwork, leaving hundreds of thousands of dollars riding on verbal agreements. When memory fails or market prices swing, finding what was said requires scrolling through months of unindexed audio memos.
01
Pricing lives only in voice memos
A broker quotes $1,240 per carat for a 4.2 carat parcel in a twenty-second audio note. The price stays on a personal handset without appearing in an accounting ledger.
02
Forty parcel groups open at once
Each parcel gets a separate chat with the buyer, broker, and cutter. Finding which of forty open groups discussed a specific VS2 clarity stone takes hours of scrolling.
03
Trapped certificate report numbers
A photo of a GIA or HRD certificate arrives taken at an angle under office lamps. The grading number sits inside that image file instead of your inventory database.
04
Broker turnover takes deal records
When a broker moves to a firm on Hoveniersstraat, five years of supplier negotiations, client preferences, and pricing notes walk out the door inside their personal SIM.
05
Verbal terms on consignment memo
Stones leave on memo after a handshake in Schupstraat. Six months later, settling payment terms depends on audio snippets that may already be deleted from a broker phone.
One parcel, end to end
What a parcel chat looks like inside
Every transaction record stays accessible to your management team without requiring brokers to type data into a separate CRM.

What matters most here
Three features this trade runs on
Multilingual audio transcription
Antwerp trading floors switch between Dutch, English, Gujarati, and Hebrew in single sentences. Speech recognition transcribes these mixed recordings and makes every quoted figure searchable by text.
Workspace record retention
Client histories, memo arrangements, and pricing negotiations remain stored in your company workspace when brokers change desks. Onboarding replacement staff takes days instead of months.
Visual certificate reading
Computer vision pulls grading details and serial numbers from photos of GIA and HRD reports taken on trading desks, linking them to the parcel conversation.
Channels
The channels carrying Antwerp trades
Brokers use WhatsApp for rapid daily buyer communication and Signal for confidential rough negotiations. CommunicationOS unifies these disparate networks into one searchable desk archive.

The quarter
One square kilometre of global trade
Along Hoveniersstraat, Rijfstraat, and Schupstraat, billions in rough and polished stones change hands each year. The Diamond Club van Antwerpen, HRD Antwerp, and the AWDC anchor a community where the same twelve brokers share forty overlapping group chats. Deals happen on the pavement through handshakes and voice memos, making organised digital records essential for protecting the house.

Will our brokers resist using this software on their desks?
Brokers continue using standard WhatsApp and Signal interfaces on their mobile phones without changing daily habits. They do not log into a complex CRM or type manual deal summaries. The platform indexes the audio and the photos in the background.
How accurate is audio transcription for Gujarati and Dutch diamond terminology?
Our speech models recognise trade-specific terminology such as make, clarity grades, and parcel weights across Dutch, Gujarati, English, and Hebrew. The system transcribes rapid speech even when brokers mix languages in the same sentence.
Can we restrict junior brokers from seeing partner client conversations?
Account permissions let you restrict access by desk, seniority level, or channel. Management reviews full floor records and audit logs while individual brokers see only their assigned accounts and client chats.
