Yellow Diamonds: Differences in Grades & Value

Many buyers associate diamonds with icy, colorless clarity, but in fact, diamonds can come in many colors, including pink and blue. One color that has seen some popularity in recent years is the yellow diamond.

Yellow diamonds, sometimes called canary diamonds, are always created by one of two things — the color may be either introduced artificially or found in nature. Natural yellow diamonds get their color from the presence of nitrogen molecules.

 

Is a Yellow Diamond Rare?

White diamonds are graded from D to Z in terms of purity of color. As they get closer to Z, they take on a yellow hue due to imperfections and decrease in value. Once natural diamonds are completely out of this range, they can take on a deep, rich color and their beauty becomes sublime. These diamonds are referred to as “fancy colored.”

Only a small percentage of mined diamonds have a deep, true color. Of these, the majority are yellow. Therefore, while natural yellow diamonds are still very rare, they are much easier to find on the market compared to other fancy colored diamonds.

Difference Between a Manual and Automatic Watch

Watches are a timeless piece of jewelry that suggests refinement and class. These timepieces come in a variety of styles and features, which are essential for the aesthetic. Another factor to consider for watches is the types of watch movements.

The mechanical style watch is either manual or automatic. Their similarity is that both watches are wound by a spring, and their energy builds through components inside the watch. The tension in the spring releases and this energy goes to the gear train; then the hands of the watch move and you can utilize it to tell the time.

The differences between a manual and an automatic watch come into play when analyzing how you wind them. No one style is better than the other for market value, so choosing the right watch comes down to your lifestyle preferences and the features you want.

Read through our guide on manual and automatic watches to decide which is best for you.

What is the Worth of a Diamond?

Almost all diamonds share similar traits. They sparkle. They delight. They adorn. Yet, to a jewelry investor or a gemstone collector, each diamond has a specific value that transcends its natural beauty.

Auction consignors and their preferred auction houses must, therefore, determine the market value of every diamond. However, approximating a diamond’s likely selling point involves digging deeper into the diamond itself. Below are some of the factors that help indicate how much a diamond is worth within a national or global marketplace.

Evaluating the 4Cs of a Diamond

Most diamond owners or buyers have heard of the 4Cs: Cut, Clarity, Carat weight and Color. Gemologists and jewelers lean on these four factors to help them define a diamond.

Without the 4Cs, which were established nearly 70 years ago, diamonds would be challenging to differentiate objectively. The 4Cs provide a solid platform that everyone can agree upon. For instance, the color of a diamond has a strong impact on its worth. Usually, the closer to colorless a diamond is, the more highly it is prized. Therefore, a truly or practically clear diamond will have a better color grade than one with a yellowish tint. However, the color isn’t always bad. The general rule of thumb is, if a diamond is colored, the more intense the color the better.
