Yellow diamonds, also known as Canary Diamonds, add a stunning shine to any piece of jewelry. They are used more frequently in wedding bands and engagement rings, modernizing the traditional bride’s appearance to reflect the latest trends in diamond fashion. The most common choice for colored diamonds is yellow, which is offered at various price points.
Definition Of Yellow Diamond
Diamonds represent fidelity and love. Yellow is a color that stands for intelligence, intellect, and knowledge. It is a vibrant, upbeat color that makes people feel happy and optimistic. An engagement ring with a yellow diamond represents the start of a joyful and loving life.
Source of yellow diamonds
Although these gemstones can be discovered anywhere in the world, South Africa is where they are most frequently found. They come in every size and shape. Each diamond is distinct and has a different color intensity ranging from pale to brilliant yellow.
Modified yellow and pure yellow are two tones. Pure yellow is the ideal shade for a yellow diamond. The majority of yellow diamonds do, however, have some secondary hue. Common variations of yellow color in diamonds include yellow with a greenish and orangey touch.
Even though the real yellow diamond is the most popular, many people prefer lab-made diamonds and are glad to pay less for them than they would for a comparable-sized diamond in pure yellow. Therefore, although orange yellow is more expensive and sought-after than greenish yellow, it is the more prevalent secondary hue.
The Function of Nitrogen in the Color Yellow
Carbon atoms make up diamonds, which are firmly held with each other in a lattice by potent covalent bonds. As a result, they are colorless when made entirely of carbon and have no structural flaws or imperfections.
Because the nitrogen atoms are so tiny, they can replace carbon atoms in the crystal structure of a diamond. Diamond crystals with nitrogen traces in place of carbon in their lattices can selectively transmit yellow light while blocking the blue light. This will give those nitrogen-containing diamonds a yellow hue. The most frequent carbon-substituting impurity, nitrogen, can make up as much as one percent of a diamond’s mass.
Capes and the Canaries
Capes and canaries are two common names for yellow diamonds. The term “Cape” first appeared in the late 1800s, when mines in the South African province of Cape produced a lot of diamonds with a clear yellow tint. Diamond industry experts soon became aware of them in the market and started referring to them as “Capes” due to their origin in the Cape Province.
These diamonds would be graded as “fancy-colored diamonds” if they were assessed today because of their light coloring, which would allow them to fall within the color range of D to Z. Regardless of where they came from, many diamond professionals still refer to light yellow diamonds as “Cape” stones.
Diamonds in Yellow and Treatment
Brown diamonds have been treated to create yellow diamonds. HTHP, irradiation, coating, and annealing are some of these processes. Some of these procedures may be reversed or altered if the diamond is heated during jewelry repair. Heat, chemicals, or abrasion can all harm these.
Yellow diamonds that have undergone treatment to change their color must be sold for less than the natural colored diamonds. Additionally, the buyer should be made aware of any unique maintenance needs. Diamonds that have been treated are not popular among buyers. They desire natural-colored stones and are prepared to pay more for them. However, some buyers are happy to get a treated stone since it allows them to purchase a look-alike diamond at a lower price.
