Leon Mason, cofounder of Mason-Kay, died of Alzheimer’s disease in Denver on July 24. He was 74.
Mason’s company, which he founded with brother-in-law Don Kay, was known for its colored stone jewelry—particularly its jade.
“His most lasting legacy might well be his gentlemanly manner and absolute integrity,” said a company statement, recalling Mason’s business advice to his son: “Always leave room for your customer to make a profit.”
A 50-year veteran of the business, Mason is survived by his wife, Ellen; his children Jeff, Tami, and Danny; and six grandchildren.
