What was Oppenheimer's strategy during low diamond demand in the 1930s?

During the 1930s, Oppenheimer's strategy during periods of low diamond demand primarily involved shutting down operations at De Beers' mines. This approach was a part of a broader strategy to control the supply of diamonds in the market. By reducing production, Oppenheimer aimed to stabilize prices and maintain the value of diamonds during a time of economic uncertainty and decreased consumer spending.

When demand for diamonds drops, maintaining a steady price is essential. By curbing production, De Beers could prevent an oversupply of diamonds, which would otherwise lead to a further decline in prices. This not only helped protect existing market value but also positioned the company to respond effectively when demand recovered.

The other strategies mentioned, such as increasing marketing efforts, investing in new technology, or expanding into new markets, while potentially beneficial in a different context, were not the primary tactics employed by Oppenheimer during that particular period of low demand. Instead, his focus was primarily on controlling supply to bolster and maintain diamond values during challenging economic times.
