Any sedimentary rock that forms, as sediments settle out of a solution, is called a chemical sedimentary rock. Sediments can settle out of a solution either by the liquid in the solution evaporating, or by too much of the sediment dissolving in the solution (called supersaturation).
A lozenge (â), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and it is sometimes used simply as a synonym (from the French losange) for rhombus. Most often, though, lozenge refers to a thin rhombusâa rhombus with acute angles of less than 45Â°.
Diamonds are cut in many different and exciting shapes. The shape of a diamond is often confused with its cut. Shape refers to the basic form of the diamond: round, emerald, oval or pear shaped, for example. Cut or proportions refer to the ability of each of these diamond shapes to reflect light.val shape diamonds are also popular because their length can help create the appearance of long, slender fingers. With Oval shape diamonds avoid what is called a Bow Tie effect, a very noticeable darkened area in the shape of a bow tie towards the middle of the Oval cut diamond.
