The best color diamond is generally considered to be the colorless or white diamond. These diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). In the diamond industry, colorless diamonds with a higher grade (closer to D) are highly valued due to their rarity and desirability. Colorless diamonds allow more light to pass through, creating a dazzling sparkle and enhancing the overall brilliance of the stone. They are often more expensive compared to diamonds with visible color. However, it's important to note that diamond color preference is subjective and some individuals may prefer fancy colored diamonds like vivid yellows, pinks, or blues, which are also highly sought after and can be quite valuable.
The cut that is considered the best for a ruby is the oval cut. The oval cut is a popular choice for rubies because it accentuates the gemstone's color and brilliance. This cut features a symmetrical oval shape with 58 facets, allowing light to enter and reflect within the stone, creating a stunning sparkle. The elongated shape of the oval cut also helps to create the illusion of longer, more slender fingers when set in jewelry. However, it is important to note that the best cut for a ruby ultimately depends on personal preference. Other popular cuts used for rubies include round, cushion, and emerald cuts. Each of these cuts offers a unique appeal and can enhance the beauty of the ruby in its own way. It is recommended to consider the characteristics of the ruby, such as its size, color, and clarity, along with personal style and preference, when choosing the best cut for a ruby.
Orange topaz can be both natural and treated. Natural orange topaz is relatively rare and is usually pale in color. However, most orange topaz on the market is commonly treated or enhanced to achieve a vibrant orange hue. This treatment usually involves irradiation and heat. Natural orange topaz can also exhibit imperfections or inclusions, whereas treated topaz may have a more flawless appearance. It is important to note that the term 'natural' in gemstones refers to the origin of the gem, rather than its treatment.
A spinel diamond is a term that does not accurately describe any actual gemstone. Spinel and diamond are two distinct gemstones with different chemical compositions and physical properties. While spinel is a mineral composed of magnesium, aluminum, and oxygen, diamond is made up of carbon atoms arranged in a crystal lattice structure. Spinel is typically found in a variety of colors, including red, blue, purple, and pink, while diamonds are known for their exceptional hardness and brilliance. As such, a spinel diamond is essentially a misnomer or a misunderstanding, as the two gemstones are separate entities with their own unique characteristics.
The highest quality grade of ruby is known as Pigeon's Blood ruby. This term is used to describe rubies with a vivid red hue, often with a hint of blue. Pigeon's Blood rubies are highly valued and sought after in the gemstone market. To be classified as a Pigeon's Blood ruby, the gemstone must possess exceptional color, clarity, and brilliance. The term originated from the belief that the color of the gemstone resembled the color of a freshly killed pigeon's blood. Rubies with this intense, pure red color are extremely rare and command premium prices. It is important to note that gemstone grading can vary depending on different sources and regions. While Pigeon's Blood ruby is considered the top grade of ruby, there are other classifications and grading systems used in the industry to determine the quality and value of rubies.
