Diamond Education
Diamond Education
Expert guidance on diamond cut, color, clarity, carat weight, and choosing a diamond that looks beautiful in real life.
Carat measures weight, not visible size. Learn how millimeter spread, shape, depth, girdle thickness, and setting style determine how large a diamond actually looks.
Learn how D–Z diamond color grades appear in real life—and how cut, shape, size and metal affect what your eye actually sees.
Learn what diamond clarity grades really mean, how to identify an eye-clean diamond, and why inclusion type and location matter more than the letter grade alone.
Learn what cut quality really controls, why top laboratory grades still vary, and how Osiris evaluates real-world visual performance.
A practical guide to evaluating cut, face-up size, shape, clarity, video, and setting compatibility—beyond the grades on the certificate.
