All about Rubies

Ruby is one of the most treasured and valuable gemstones in the world, renowned for its striking red color and timeless beauty. Here is a detailed write-up about ruby gemstones, including their characteristics, origins, historical significance, and more:

Characteristics of Ruby:

Color: Rubies are known for their vibrant red color, which ranges from pinkish-red to deep crimson. The intensity and hue of red are essential factors in determining a ruby's value.
Hardness: Ruby is one of the hardest gemstones, with a score of 9 on the Mohs scale of mineral hardness. This exceptional hardness makes it highly durable and suitable for daily wear in jewelry.
Clarity: Rubies can contain natural inclusions, which are often referred to as "silk." These inclusions can affect a ruby's clarity, but they can also create a unique texture known as asterism when cut into cabochons.
Cut: Rubies are typically faceted to enhance their brilliance and sparkle. The most common cuts for rubies are oval, round, and cushion, although they can be cut into various shapes depending on the rough stone's characteristics.
Carat Weight: Rubies come in a range of sizes, and larger rubies are rarer and more valuable. The price per carat tends to increase significantly with size for high-quality stones.

Origins of Ruby:

Burmese Rubies: Myanmar (formerly Burma) is historically celebrated as the primary source of the world's finest rubies. Rubies from the Mogok Valley and Mong Hsu region are particularly famous for their exceptional quality, known as "pigeon's blood" red.
Thai Rubies: Thailand has been a significant source of rubies, with regions like Chanthaburi and Trat producing gems with rich red colors, albeit slightly darker than Burmese rubies.
African Rubies: African countries like Mozambique, Tanzania, and Madagascar have emerged as important ruby producers. Mozambique, in particular, has yielded high-quality rubies, often resembling the color of Burmese rubies.

Historical Significance:

Throughout history, rubies have held a special place in various cultures. They have been associated with love, passion, and protection. In ancient times, they were believed to possess magical and protective powers.
Rubies were often worn by royalty and nobility as symbols of power and wealth. They adorned crowns, jewelry, and ceremonial regalia.

Treatment and Enhancement:

Many rubies on the market undergo heat treatment to improve their color and clarity. This is a common practice and is generally accepted within the gemstone industry.
Other treatments, such as fracture filling with lead glass or lattice diffusion with elements like beryllium, are less accepted and should be disclosed when purchasing a ruby.

Value and Investment:

High-quality, untreated Burmese rubies with a rich, red color are among the most valuable gemstones in the world and can command prices even higher than diamonds of similar size.
Rubies are often considered a valuable investment, particularly when they exhibit exceptional color, clarity, and size. However, like all investments, it's essential to work with reputable dealers and have a good understanding of the market.

In conclusion, rubies are enduring symbols of passion, love, and luxury.

When considering purchasing a ruby, it is advisable to consult with a certified gemologist or a trusted jeweler to ensure you acquire a gemstone of exceptional quality and value.

Ruby, one of the most precious gemstones, is often graded based on specific characteristics that determine its quality and value. These grades help gemologists and jewelers classify rubies and inform buyers about their quality. Here are the special specific grades of ruby:

Color Grade:
- Pigeon's Blood Red: This is the most coveted and valuable color grade for rubies. Pigeon's blood red rubies exhibit a pure, intense, and vivid red color with a slightly bluish undertone. The name is derived from the rich, deep red hue of a pigeon's blood.
- Vivid Red: Rubies falling just short of the pigeon's blood grade may be referred to as "vivid red." These gems still display a strong, vibrant red color and are highly prized.
- Burmese Ruby: Rubies from Myanmar (formerly Burma) are renowned for their exceptional color and are often considered the standard for high-quality rubies.
Clarity Grade:
- Eye-Clean: Rubies with minimal to no visible inclusions under normal viewing conditions are considered eye-clean and are highly valued.
- Slight Inclusions: Rubies with minor inclusions that may be visible under close inspection but do not significantly impact their beauty and durability.
- Included: Rubies with noticeable inclusions that may affect their transparency or brilliance. While included rubies are less valuable, their price may vary depending on the nature and location of the inclusions.
Cut Grade:
- Ideal Cut: Rubies with precise and well-proportioned cuts that maximize their brilliance and color are graded as ideal. These cuts are often symmetrical and showcase the ruby's beauty.
- Good Cut: Rubies with good but not perfect proportions, which still exhibit good brilliance and color, are graded as having a good cut.
- Poor Cut: Rubies with proportions that do not effectively reflect light and may negatively impact their beauty.
Carat Weight:
- Large Carat Weights: Rubies of larger carat weights are rarer and more valuable. Extremely large rubies, especially those with high-quality color and clarity, can be exceptionally valuable.
Origin Grade:
- Burmese Ruby: Rubies from Myanmar (Burma) are often considered the most prestigious due to their historical significance and exceptional color. They may command higher prices.
- Mozambique Ruby: Mozambique has become a significant source of high-quality rubies in recent years, and Mozambican rubies are valued for their rich red color.
- Other Origins: Rubies from other countries, such as Thailand, Sri Lanka, and Madagascar, may also have their own origin-based grades.
Treatment and Enhancement Grade:
- Untreated: Rubies that have not undergone any treatment or enhancement are often preferred for their natural beauty.

Heated: Many rubies are heat-treated to enhance their color and clarity. Heat treatment is an accepted industry practice, and the degree of heating can affect the grade and price.
