This page is dedicated to current carat values at mines or projects.
*Information in this current blog is based on information obtained up to mid 2018 and should be considered legacy at this time and should no longer be relied upon.*
Initially with Canada only.
The information below is obtained (best efforts basis) from various sources from the web. Please do further due diligence before assuming all the information below is 100% accurate.
A lot of the data below is stamped with a certain date/time. There is a published index that Paul Zimnisky creates and that could be roughly used to estimate current prices -- Diamond Index
Peregrine Diamonds
Chidliak CH-6 (Feb 26, 2014)
US$162 - Minimum modeled price
US$188 - Base Case modeled price
US$236 - High modeled price
(Price Book - Feb. 24th, 2014)
"Because the four largest diamonds have exceptionally high values, the actual price was higher than the base case modelled price. Mr. Neil Buxton, responsible for geostatistical modelling at WWW stated "Based on our analysis of the parcel, WWW believes that if CH-6 were in production in the current diamond market, it is highly unlikely that the average price would be lower than the minimum modelled price. It is also important to understand that the high modelled price does not represent a maximum price and that the ultimate average diamond price in a mine production scenario could be higher than US$236 per carat. Given the number of large stones in this parcel, and their relatively high value, even the high modelled price may be considered conservative." "
In January 2015, Mr. Neil Buxton issued the following statement:
“WWW International Diamond Consultants (WWW) valued the Chidliak diamonds in February 2014, and prices increased steadily through to August 2014 before liquidity concerns in the diamond markets became a reality. This was exacerbated by the Antwerp Diamond Bank (ADB) announcing that it was withdrawing from the diamond business. It is estimated that ADB was financing $1.6bn to the diamond trade or eleven percent of the total $14.5 billion of debt. At the same time wholesale polished diamond prices softened in the last quarter of 2014. As with other commodities, there is currently a degree of uncertainty in the market and the WWW overall rough price index currently stands 6 percent lower than in February 2014.”
Chidliak CH-7 (March 8, 2016)
US$94 - Minimum modeled price
US$114 - Base Case modeled price
US$155 - High modeled price
(price book Feb. 1st, 2016)
"Mr. Neil Buxton, responsible for geostatistical modelling at WWW stated “based on our analysis of the parcel, WWW believes that if CH-7 were in production in the current diamond market, it is unlikely that the average price would be lower than the low average modelled price. It is equally important to understand that the high average modelled price does not represent a maximum price and that the ultimate diamond price could be higher than US$155 per carat. These results need to be confirmed with a larger sample."

Renard 65 bulk sample (April, 2013)
US$169 - Minimum modeled price
US$180 - Base Case modeled price
US$203 - High modeled price
Renard 2 (valuation update - Mar 2013)
US$151 - Minimum modeled price
US$190 - Base Case modeled price
US$214 - High modeled price
Renard 3 (valuation update - Mar 2013)
US$141 - Minimum modeled price
US$151 - Base Case modeled price
US$185 - High modeled price
Renard 4 (valuation update - Mar 2013)
US$98 - Minimum modeled price
US$104 - Base Case modeled price
US$168 - High modeled price
"In the case of Renard 4, independent studies on diamond breakage and poor plant performance during the processing of the bulk sample have previously indicated that the size distribution of the Renard 4 diamond sample has been artificially modified during recovery. Should this prove to have been the case, a higher diamond price estimate for the Renard 4 kimberlite might still be expected."
