Fancy color diamonds can be extremely valuable but can also be very inexpensive. Brown and yellow are the two most common colors occurring in diamond and therefore are the least expensive. Gray, which is less common, can also be considered a fancy color, but also inexpensive. Light fancy yellows begin to rise in value but are still considered common and are less expensive than its colorless or near colorless counterparts. “Fancy yellows”, begin to pick up value due to their higher saturation of color, rarity and demand. “Intense” and “vivid fancy yellows” are the most valuable in the yellow hue, especially in larger sizes.
