Clue Mystery Puzzle: Diamonds Can Be Deadly - 1993
The Story:

Eccentric Dr. Black has a passion for collecting almost anything. Now he must sell his Black Star diamonds necklace in order to expand his varied collections. Only his closest friends are invited to private auction, but unbeknownst to him, one was the necklace a little too much. That someone will take it at any cost! Even if it means taking Dr. Black's life too!

Sometime during the bidding, the real necklace disappears, and a paste substitute is put in its place! When Dr. Black surprises the slippery fingered thief later, the result is murder... ! Who is the thief-turned-murderer? And where is the precious necklace hidden?
The Suspects:

Mrs. Elizabeth Peacock: How badly did she want the Black Star necklace back among her family jewels? Did the Peacock legacy lead to murder?
Professor Peter Plum: Passionately in love with Miss Scarlett, was he desperate enough to steal the necklace for her engagement present?
Mrs. Blanche White: Did her sticky-fingered past make her grab that beautiful diamond while she still could?
Reverend Jonathan Green: An amateur gemologist, did he admire the Black Star a little too much and want it for his own?
Miss Vivienne Scarlett: Appearances are everything to her. When she's dressed in diamonds, is she dressed to kill?
Colonel Mike Mustard: After being jealous of Dr. Black for years, did the Colonel see the necklace as his own ticket to wealth and glory?
