The man and woman approached the woman Friday and offered to sell her diamonds valued at $20,000, police reported. The woman offered $1,000 for one of the diamonds and took the suspects to her sister, a Livermore resident, who paid another $6,000 for the second diamond.
Following the transaction and after the suspects left, the sisters learned the "diamonds" were of little or no value, according to police.
The male suspect is described as being about 50 years old and the woman is about 30 years old. They both speak Spanish. They were driving a blue four-door vehicle.
