Answer
How do I buy a diamond from a wholesaler in Bedfordview?
The wholesale floor is appointment-only. Most Bedfordview operations sit in unmarked offices in low-rise commercial buildings; you book ahead and walk in. The conversation starts technical: the dealer expects you to know what triple-excellent means, what the difference between H and I colour looks like to the eye, and where on the GIA clarity scale you are comfortable.
The seven practical steps. One: book the appointment in advance. Two: bring a written brief, carat band, colour grade, clarity grade, cut grade, budget. Three: ask to see three stones in your envelope side by side. Four: get the GIA report on each in writing before discussing price. Five: verify each report number on the GIA database before signing. Six: confirm the Kimberley Process declaration on the invoice. Seven: ask the dealer which of the three they would buy themselves and why; if they say all three, walk.
The longest-running Bedfordview operation is ProDiam Trading; the corridor itself is documented in Where Johannesburg’s diamond money actually goes. The bespoke commission process is laid out separately in Bespoke in Bedfordview: a four-week commission, documented.
