Light is what gives a diamond its life.
Much of what people respond to in a diamond comes back to light. Brightness, fire, contrast, and movement all shape the way a stone feels once worn, which is why two diamonds can appear very different even before color or clarity become part of the conversation.
A few essentials.
A clear starting point for understanding the bright white light people notice first.
How flashes of colored light appear, and why they feel different from brightness alone.
The movement and contrast that make a diamond feel alive once it begins to move.
