Harry Winston Diamond Corporation reports Diavik Diamond Mine Second Quarter 2012 Update

July 17, 2012

TORONTO, July 17, 2012 /PRNewswire/ – Harry Winston Diamond Corporation
(TSX:HW, NYSE:HWD) (the “Company”) reports that in the second calendar
quarter of 2012, the Diavik Diamond Mine produced 1.79 million carats
from 0.5 million tonnes of ore processed.  Ore volumes processed and
diamonds recovered are consistent with the comparable quarter of the
prior year.

For the first half of the calendar year 2012, the Diavik Diamond Mine
produced 3.4 million carats from 1.1 million tonnes of ore processed
compared to production of 3.1 million carats from 1.0 million tonnes of
ore processed in the comparable period of the prior year.  Ore volumes
processed for the first half of the current year included production
from the A-154 South underground using the sub-level retreat mining
method that commenced in July 2011.  Diamonds recovered for the current
year are also higher than in the comparable period of the prior year
due partially to increased high-grade ore and lower mud-rich type B ore
mined from the A-418 kimberlite pipe in 2012.

Diavik’s full-year target production remains at 8.3 million carats.
Production in the second half of the year is forecast to be higher than
the first half of the year due to a ramp-up of carats recovered from
A-418 underground plus the processing of approximately 1.0 million
carats of reprocessed plant rejects (“RPR”).

The rough diamond market has experienced softened demand since the
beginning of the year. The Company held partial rough diamond sales in
May and June, and the July sale has just commenced and the Company
expects higher than normal rough diamond inventory at July 31, 2012.
Based on prices from the Company’s last complete rough diamond sale and
the current diamond recovery profile of the Diavik processing plant,
the Company has modeled the approximate rough diamond price per carat
for each of the Diavik ore types in the table that follows. The Company
estimates that current market prices have declined by approximately 4%
from the beginning of the fiscal year and by approximately 8% since the
Company’s March/April 2012 sales.

    |Ore Type        | March and April 2012  |
    |                |Average Price per Carat|
    |                |    (in US dollars)    |
    |   A-154 South  |              $160     |
    |   A-154 North  |              $205     |
    |A-418 A Type Ore|              $145     |
    |A-418 B Type Ore|              $100     |
    |         RPR    |               $55     |
