‍

The Origin and Sources

Beyond aesthetics, the origin of a gemstone plays a major role in its characteristics. Theoretically, a diverse range of color and quality can be discovered across the different origins, however, the reality is that some areas are more renowned for specific qualities in comparison. 

‍

Sapphires: 

Of all the sapphires out there, the Ceylon Sapphire of Sri Lanka is regarded as the world’s best, and is distinguished and celebrated for their excellent brightness, brilliance and saturation. 

The North-Western Himalayan region of Kashmir has historically produced sapphires with a mesmerizing, velvety blue color; these mines are now largely exhausted, making the Kashmiri sapphires exceedingly rare and valuable. 

The Burmese sapphires are revered for their deep, velvety blue tones, with needle or silk inclusions revealed only through close examination under a microscope or a jeweler’s loupe.

‍

‍

Rubies: 

The Mogok Valley in Myanmar is renowned as the historical source of some of the world’s most exquisite rubies. The Burmese rubies are celebrated for their pure, vibrant red hues, often referred to as “pigeon blood” red. Thailand and Cambodia also have significant ruby deposits. In recent years Mozambique has emerged as a major player in the ruby market, producing a considerable quantity of fine quality rubies.

‍

‍

Emeralds:  

The most famous emerald mines are located in Colombia, where the Andes Mountains yield emeralds with an unparalleled, vibrant green color. These Colombian emeralds are often considered the finest due to their rich saturation and impressive clarity. Zambia and Brazil are also major sources of emeralds, each producing gemstones with distinct characteristics. Zambia is known for its slightly bluish-green emeralds, while Brazilian emeralds often exhibit a forest green color.

Understanding the Chemical Compositions

Understanding the chemical composition of sapphires, rubies and emeralds not only define the aesthetic appeal of these gemstones but also contribute to their rarity and value in the world of jewelry and gemology.

Sapphires:

Sapphires are formed beneath the earth’s surface under immense pressure and intense heat out of corundum, a rock-forming mineral and crystalline form of aluminum oxide (Al₂0₃). The rich blue color of the sapphires is derived from iron and titanium which is incorporated into their crystal structure.  Sapphires come in various colors, ranging from blue to yellow, green, orange, and pink, depending on the specific trace elements present. Iron and titanium create blue sapphires, while yellow sapphires often contain more iron, and green sapphires result from the presence of both iron and chromium. 

Rubies: 

Similar to sapphires, rubies too are predominantly composed of a variety of corundum (Al₂0₃), however the presence of chromium in the crystal lattice lends the gemstone of its signature deep red hue. The level of chromium and the specific conditions during the gem’s formation determine the intensity and shade of red in a ruby. 

Emeralds: 

The primary chemical formula for emeralds is Be₃AI₂(SiO₃)₆, which signifies the composition of beryllium, aluminum, silicon, and oxygen. The striking green color of the emerald is derived from the presence of chromium and vanadium; Chromium gives emeralds their intense green color, while vanadium contributes to their saturation and brilliance. The purity and intensity of green in an emerald are essential factors that determine its value and desirability in the market.

Evaluating the Quality and Values of these Gemstones 

In the enchanting world of gemstones, evaluating the worth and beauty of sapphires, rubies and emeralds is a delicate art.

‍

A. Value Factors (4Cs)

When evaluating the value of sapphires, rubies, and emeralds, the “Four Cs” – Color, Clarity, Cut and Carat weight – are essential for determining their worth. 
‍

1. Color Intensity and Saturation

Colored gemstones are characterized by the interplay of three key attributes: hue, saturation, and tone. Hue refers to the gem’s dominant color, saturation represents the intensity of that hue, and tone measures the gem’s darkness or lightness.

‍

Sapphires are most revered for their deep blue hues, with the most prized shades being those of vivid intensity. Rubies attain their highest value with a pure, intense red or pinkish-red color, free from any hints of brown. Exceptional rubies, often referred to as “pigeon’s blood” rubies, display a vivid, pure red color with a slight bluish undertone, making them highly prized in the world of gemstone. For emeralds, the emphasis is on a rich green color, with the most valuable gems exhibiting intense, vivid green hues.

2. Clarity and Transparency

The value of these gemstones are often influenced by their clarity levels, which involves a close examination of the gemstone’s interior for inclusions. Some gem species commonly contain many noticeable inclusions, while others typically carry a few. Terms such as “eye-clean” and “loupe-clean” are commonly used to describe gemstones that are free of visible inclusions or blemishes to the naked eye or when examined under a jeweler’s loupe that inspects gemstones with magnification.

Sapphires typically have good clarity with fewer inclusions compared to emeralds, however it is important to note that despite inclusions’ effect on transparency, it doesn’t detract from its beauty. Gemstones with eye-clean clarity are the most valuable and highly desired among sapphire lovers. Similarly, rubies too have better clarity compared to emeralds, with inclusions usually less visible to the naked eye. Rubies with eye-clean clarity are similarly desired and highly prized, however, the vividness of the red color in rubies generally take precedence over clarity when determining its value. Emeralds often have more inclusions, with the most common being “jardin” or garden-like patterns and these inclusions are typically seen as part of the gem’s character. While clarity is considered important when determining the value of emeralds, depth and intensity of the color often take precedence. ‍
‍

3. Cut and Shape

Sapphires are well suited to a variety of cuts, with the most popular shapes being oval, round, and cushion. Rubies are typically cut to maximize their color and brilliance, with most common shapes being oval and cushion that amplifies the stone’s deep red hue. Emeralds are often cut with rectangular or square step cuts to minimize the impact of inclusions and to enhance its natural color.

‍

‍

4. Carat Weight

Across the board, larger stones are often more valuable if other quality factors are in line. Simply said, the bigger the gem, the greater its value.

‍

B. Grading systems and standards

Sapphires, rubies, and emeralds are universally assessed using the 4Cs - color, clarity, cut and carat weight.

As detailed in the previous section, these four pillars serve as the fundamental framework and the foundation for grading systems and standards to assess the quality and value of these gemstones.

‍

C. Other Factors that can Affect the Value

Origin is a crucial determinant of value, with sapphires sourced from Kashmir, Myanmar, and Sri Lanka are particularly valued. Fine rubies from Myanmar have a historical reputation for their exceptional quality, while emeralds from Colombia are celebrated for their lush green hues.

Treatment and enhancements also play a role, commonly practiced to improve the visual appeal of gemstones. Traditional treatments like heat treatment is a standard practice to improve the color and clarity of sapphires and rubies. Emeralds are often treated with oils like cedar wood to improve their clarity and transparency. However, unheated stones in particular hold greater value, while certain treatments may negatively impact a gemstone’s value.

Lastly, market demand can fluctuate, affecting the prices of these gemstones. Sudden surges in popularity or the influence of trends can drive up prices for certain colors or types of gemstones.

‍

Care and Maintenance

Proper care and maintenance are essential to preserve the beauty and value of sapphires, rubies and emeralds.
‍

Cleaning and storing gemstones

Regular cleaning helps maintain the gemstone’s luster and brilliance. Sapphires, being relatively durable, can be cleaned with mild soap and warm water using a soft brush to remove dirt and oils. Rubies and emeralds require more caution, as they may have surface-reaching fractures. A gentle rinse with warm water and a soft cloth is typically safe, but it's important to avoid harsh chemicals and abrasive cleaning agents. When not in use, store your gemstone jewelry in separate pouches or boxes to prevent scratching. It’s wise to keep them away from other gemstones to avoid any potential damage.
‍

Handling and wearing precautions

When handling these precious gemstones, it’s important to treat them with care. Avoid exposing them to sudden temperature changes or extreme heat, as this can cause stress fractures. Be cautious when wearing your jewelry, especially rings, as these gemstones can still be scratched or chipped despite their hardness. Remove jewelry when engaging in activities that may subject the gemstones to impact, such as sports or manual labor.

Additionally, it’s advisable to protect your gemstone jewelry from contact with chemicals, such as those found in household cleaners, perfumes, and cosmetics, as these substances can dull the gemstone’s appearance and potentially harm their surfaces.
‍

Professional services for cleaning and repairing

Regular professional maintenance can ensure the longevity of your sapphires, rubies, and emeralds. Periodic inspections and cleaning by a jeweler can help identify any potential issues with your gemstone jewelry. They can check for loose settings, worn prongs, or other signs of damage.

If necessary, a professional can clean your jewelry safely and advise on any repairs needed. In the case of emeralds, oil treatments, which are common to enhance clarity, may deteriorate over time, requiring re-oiling by a skilled gemologist. Proper re-oiling can restore the emerald’s vibrant appearance. Trusting your gemstone jewelry to professional services is a valuable investment in preserving their beauty and value.
