For snow of an average snowpack temperature, say around 5 degrees C, the critical temperature gradient is about one degree centigrade per 10 centimeters (1 deg C. 10 cm.). In cold snow, say colder than 10 deg. C, you need a higher temperature gradient to cause faceting and in warm snow you need slightly less.
Welcome to the Gemology Online Faceting Diagram database! All patterns on this page were written by faceters on this site. To access the diagrams, simply click on the image of the stone. To view the image up close, click on the small "picture in picture" icon in the lower right corner.
The process of faceting happens in seemingly benign conditions. During cold, clear, and calm spells, the snow undergoes a process known as metamorphism.
Faceting Design Diagram: “CC” Triangle – Beryl – Aquamarine, Emerald, Helidore, Bixbite, Goshenite, Morganite, Golden Beryl. Information and guide for Faceting Design Diagrams. This design is called a ” “CC” Triangle”. Roughing in the table before you cut the C5 is a good….
As we discover in Learning Goal 7i(surface hoar), under clear, calm conditions at night, very strongtemperature inversions can happen just above the snow surface. Thus,even on a night where the air temperature (typically measured 2 m abovethe surface) is 8°C, the snow surface could be around 18°C.
From the time snow crystals fall from the sky to time they melt in the spring, the shape and structure of each crystal never stops changing. This is known as snow metamorphism. Snow metamorphism determines if individual snow crystals are rounding (becoming stronger) or faceting (becoming weaker). The relationship between snow crystals ultimately dictates what kind of layer, strong or weak, is formed.
During cold, clear, and calm spells, the snow undergoes a process known as metamorphism. Those beautiful stellar snowflakes that fell from the sky immediately start to change the moment they hit the ground. For faceting to occur, a temperature gradient must exist, or there must be a difference in temperature between the ground and the air.

This makes it one of the most fun, challenging, and satisfying materials – as well as one of the most instructive for building faceting skills. This is because Sunstone has at least six major challenges that offer stellar learning opportunities for the faceter building his skills – all the way from the most basic level to the most advanced.
