RE: Lace Mine rough tender in Antwerp.3 Sep 2016 19:03
The sales process for diamonds must be a bit longer than normal stuff. I suppose the pacel takes a few days to get them ready, prepare the export docs (which then has to pass customs etc taking another few days). They could have sold these on August tenders around 20th but because of these time consuming 'processings', you never could.
So I assume they had everything ready by the end of August & then (according to Vals comment earlier):
The 'lots' should currently be open to viewing & assessment probably from around 28th Aug (10 working days) ahead of start of the tender so that buyers are able to evaluate (weigh/grade/price) each stone in the various Lace lots on offer in preparation of their bids. Takes quite a bit of lead time & tedious hours especially if a buyer wants to bid on the entire batch but generally buyers are selective and focus only on size & quality their clients need.
Also I assume there are no auctions at around 30th of August or even early Sept. You wont get clients (who buy diamonds) appearing every week.
