Sightholder is:

• A. A diamond retailer who sells to consumers
• B. A diamond miner who digs rough stones
• C. A diamond manufacturer or dealer invited by De Beers to buy rough diamonds
• D. A lab that certifies gem quality

Answer: (C)

In the diamond trade, a sightholder is a diamond manufacturer or dealer who has been invited by De Beers to purchase rough diamonds during sight sessions. These sessions are regular, invitation-only events where De Beers distributes rough stones to a select group of clients who are trusted to process or resell them. This makes sightholders part of the controlled supply chain from rough to polished, rather than miners who extract stones, retailers who sell to consumers, or labs that certify gem quality. The invitation-based system gives De Beers a way to manage supply and market stability, while giving established manufacturers and dealers a guaranteed source of rough diamonds.
