Small Facets Vs. Large Facets:
”Here’s an interesting physical phenomenon that we see as we are planning our gemstone cuts. In this pic, we took a piece of synthetic spinel and cut it in half. Both stones are the exact same dimensions and nearly identical weight. Material is the same color, same piece, and isotropic so no pleochroism involved. The crown pattern on both is exactly the same. Angles on the top and bottom are the same but the number of facets and size of facets on the pavilion has changed. Notice that the blue on the left looks lighter than the stone on the right. 

Regardless of which color is more pleasing to you, these two colors have a different market price and if this were sapphire that could be the difference of hundreds of dollars, especially if this subtle shift changed the color grade on your stone certification.” ~ Justin Prim
