These modified cuts tend to have a crushed ice or needle like facet pattern, more similar to a radiant cut than a traditional cushion cut. The chart below serves as a general guideline for evaluating the cut of a cushion cut diamond.
Broadly speaking, two types of stem cell can be distinguished: embryonic stem (ES) cells which can only be derived from preâimplantation embryos and have a proven ability to form cells of all tissues of the adult organism (termed âpluripotentâ), and âadultâ stem cells, which are found in a variety of tissues in the fetus and after birth and are, under normal conditions, more specialized (âmultipotentâ) with an important function in tissue replacement and repair.
Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells. Stem cells are different from other cells in the body in three ways: They can divide and renew themselves over a long time.
