Lucapa Diamond Company reported a $1.3 million loss for the first half of the year due to a market slowdown that led to declining prices for its rough diamonds. This contrasts sharply with a profit of $64,000 during the same period last year. Total revenue dropped by 24% year-on-year to $35.6 million, with the average diamond price falling 26% to $1,213 per carat. Production also declined, with a 12% decrease to 27,362 carats from January
