black absorbs light white reflects light
An opaque white appearance under a black light may indicate that the diamond is not a true diamond but could be a simulant or synthetic stone. Natural diamonds typically do not fluoresce strongly white under ultraviolet light. It would be best to have the diamond examined by a professional gemologist for a more accurate assessment.
-- Where you see white, you see a surface that reflects all colors. If it didn't reflect all colors, you would see only the colors that it does reflect. -- Black is not a color. It's the absence of light. An object that appears black to you is one that absorbs light of all colors, so there's no light remaining to proceed from it to your eyes.
Dark colored items are those with a deep shade or low light reflection, such as black or navy. Light colored items are those with a bright shade or high light reflection, such as white or pastel colors.
White is typically more visible in the dark as it reflects more light. This is why reflective clothing and signs are often made in white or light colors to enhance visibility in low light conditions.
The retinal receptors responsible for detecting black, white, and gray colors are the rods. Rods are highly sensitive to light and function well in low light conditions, making them crucial for night vision. They do not contribute much to color vision but are essential for detecting differences in light intensity.
The photo-receptors that detect black and white movement and are primarily used at night are called rods. Rods are highly sensitive to light and enable vision in low-light conditions, allowing us to perceive shapes, movement, and shades of gray. Unlike cones, which are responsible for color vision and function best in bright light, rods do not detect color but are crucial for night vision and peripheral awareness.
Rods can only see in black and white, aka low light conditions. They also provide us with our peripheral vision. Cones allow us to see colors and give us our daytime vision.

Rod cells in the retina allow us to see in black and white and in dim light. They are specialized photoreceptor cells that are highly sensitive to light and are responsible for our night vision.
Rods are not directly involved in color vision but instead play a crucial role in low-light vision (night vision) and detecting motion. Color vision primarily relies on cone cells in the retina, which are sensitive to different wavelengths of light and allow us to perceive colors.
The rods are extremely sensitive to light and are responsible for black and white vision, while the cones are responsible for colour vision.
Rod cells are photoreceptors that do not distinguish different colors. They are highly sensitive to light and are primarily responsible for vision in dim light conditions. Rod cells do not contain the pigments necessary to perceive different colors, so their function is more focused on providing black and white vision.
Rods function in dim light and provide black-and-white vision. Cones support brighter daytime vision and the perception of color. A third type of photoreceptor, the photosensitive ganglion cell, causes reflexive responses to bright daylight.
Objects are coloured because they absorb certain frequencies and absorb others. For example a green object has absorbed red light and what was left, the green light, and so on. A white object reflects all the frequencies (colors), a black one absorbs all.
The cells that allow you to see in black and white are called rod cells, which are photoreceptor cells located in the retina of the eye. Rods are highly sensitive to light and enable vision in low-light conditions, but they do not detect color. Instead, they contribute to night vision and peripheral vision, allowing us to perceive shades of gray in dim lighting. This is in contrast to cone cells, which are responsible for color vision.
White reflects light, including all colors, while black absorbs light, including all colors. This means that white does not reflect black, but rather all colors, and black absorbs light, even white light.
