The mark consists of a set of six diamonds in the shape of a crown. The diamond design consists of three interlocking pairs of diamonds, with one pair in the middle, one pair on the left, and one pair on the right. On the inside bottom of the left pair and right pair is a half pointed arrow, with the arrows facing opposite directions. The middle interlocking diamond pair stands taller than the other two pairs. There is a star in the inside of the top diamond of the middle pair of interlocking diamonds. Inside the star is a circle containing the stylized letters "PL". The "L" is superimposed on the "P", with the vertical portion of the letter "L" encased in the letter "P". Underneath the diamond design is the wording "Pierre LeRock". Underneath "Pierre LeRock" are the stylized letters "RSTO". Under "RSTO" is the wording "ROCK SOLID THROUGHOUT". Below that is an arrow inside an elongated oval. The arrow has a round dot on the left and a half pointy tip on the right, as if the arrow was cut in half horizontally.
