Welcome to Phoenix Enterprise's extensive Moissanite Color and Clarity Chart. You will be able to comprehend the subtleties of moissanite grading and choose the best option for your unique item with the help of this comprehensive guide.
Understanding Moissanite Color
Moissanite color is graded using a letter scale that goes from D (colorless) to Z (light yellow or brown). Based on the same scale that the Gemological Institute of America (GIA) developed for diamonds, this system is widely used by moissanite suppliers to describe stone color. The GRA (Gemological Research Association) grades stones on its certifications using this scale, which goes from D to K.
Color grading quantifies a stone's lack of color. A stone's grade increases as its color becomes less noticeable.
Stone Grades
D–E–F: Colorless
The D–E–F range of stones has an icy white appearance. The highest grade, D, denotes an entirely colorless stone. Additionally, E and F are colorless, with only minimal amounts of color visible to a skilled grader at 10x magnification.
G–H–I: Near‑Colorless
Stones in the G–H–I range have minimal warmth, yet they appear white under normal lighting conditions. G has an icy white appearance despite being practically colorless. The somewhat warmer or steely white color of H and I is more noticeable when directly compared to a D-F stone.
J–K: Faint Color
Stones in the J–K range have a noticeable brownish or yellowish color. As the grade approaches K, this warmth becomes more obvious without the need for magnification.
Moissanite Hardness on Mohs Scale
Moissanite creates greater flashes of rainbow-colored light (fire) and reflects more light than diamond due to its higher refractive index. It is also extremely durable, with a Mohs hardness score of 9.25, which is the second hardest mineral on Earth, with only diamonds scoring above it with a 10.
