Outline

Ruby derived its name from the Latin word "ruber",  which translates into modern English as "red."  Popularly known as the "King of Gems" in Sanskrit texts. This exquisite gemstone comes in various red shades, ranging from pinkish to bluish red. Natural Ruby, like sapphire, is a variety of corundum and is one of the world's hardest minerals. Since the dawn of civilization, rubies have been treasured possessions of many rulers (Kings and Queens). The gemstone was prized by European royals and aristocrats more than any other gemstone during the Middle Ages.

Burma (Myanmar) has been a major source of exquisite natural rubies for centuries. Today many deposits in Mozambique, Thailand, Sri Lanka, China, Tanzania, Afghanistan, Australia, Brazil, India, Cambodia, Kenya, Madagascar, Malawi, Nepal, Pakistan, Zimbabwe, Tajikistan, the United States, and Vietnam also produce natural rubies. The Montepuez ruby deposit, found in 2009 in Mozambique, is the world's largest known ruby mine.

Ruby deposits are extremely rare, making the stone genuinely valuable. This gemstone's hardness, durability, luster, and rarity make it even more desirable. The most widely known and most pricey rubies are those that range from bright red to reddish-brown. Natural Ruby rings, pendants, earrings, and bracelets exude idyllic splendor and are a must-have in any woman's jewelry collection.

Ruby's long and illustrious history adds to its trend and relevance.

Properties

Hardness and Strength

Rubies are a red variety of the mineral corundum that gleams and exudes pure brilliance and luster. Aluminum and oxygen make up the majority of corundum. Other elements such as iron, chromium, and titanium are also present in trace amounts. Rubies are the second hardest substance on the planet after diamonds, with a Mohs hardness rating of 9.

Treatment

Natural Rubies are commonly heat-treated (meaning they are exposed to high heat to improve their color). This process produces a long-lasting result and is stable. Other treatment methods such as glass filling are used on Rubies with large fractures and display a lot of inclusions. This treatment method improves clarity and transparency, making these gemstones not termed "Natural" when applied. Glass-filled rubies have a much lower value than their "Natural" counterparts. 

 

Grades

Rubies are one of the world's most valuable precious stones and command the highest market prices among colored gemstones.  Many factors determine the quality and price of a ruby.

Color

One of the essential characteristics that make a ruby gemstone valuable is its color. Color differences of a few shades can make a big difference in value and pricing. Pure, vibrant Red with a hint of blue is the most desired color in the trade. If a ruby's color is too light, the stone is classified as a pink sapphire (pink corundum). The ruby's quality decreases as the shade becomes more orange or purple.

 

Clarity

Rubies with no inclusions are nearly impossible to find. The visibility of these inclusions plays an essential role in determining the price and value of the ruby. Noticeable inclusions and those that reduce the stone's transparency or brightness will also decrease the gem's value. Thin mineral inclusions known as needles are typical in natural rubies. Silk is the name these needles give when they form intersecting groups within the gem. Ruby inclusions can take the form of tiny crystals, color patches, or fingerprint-like patterns.

Cut

The shape of a ruby crystal determines its suitability for various cuts. A flat tabular hexagonal shape is the most popular shape for rubies. Rubies are generally cut into oval and cushion shapes, with brilliant-cut crowns and step-cut pavilions. Rubies in round, triangular, emerald, pear, and marquise shapes are also available, but larger sizes are uncommon.

All of these factors result in different quality levels. These grades are the only standardization available when purchasing rubies and ruby jewelry, even though they're not universally acknowledged.

Size

The price of a ruby per carat increases exponentially as the size of the stone increases. Natural rubies over one carat in fine quality are extremely rare, making them extremely valuable. Rubies of commercial quality are widely available in a variety of sizes.

Care Guides

Like any other gemstone, a natural ruby is susceptible to chipping or cracking when subjected to high impact, especially when set in jewelry. Foreign particles are also likely to accumulate on the surface of this brilliant gem, dulling it over time. 

Here are some helpful tips for extending the life of your gleaming rubies:


    •       When doing everyday chores, it is essential to take off your ruby ring or ruby bracelet except when it's your wedding ring.
    •       To avoid surface cloudiness, wear your ruby jewelry only after applying perfume, lotion, and hairspray.
    •       Use a soft cotton cloth to gently wipe away skin oil and make-up after wearing your jewelry.
    •       Consult your jewelry store if your ruby jewelry has been subjected to a significant impact and check for cracks or loose stones.
    •       To prevent scratches from harder stones and to keep your ruby from scratching softer stones, store them separately by wrapping them in pouches or in jewelry safety boxes with separated chambers.
    •       When cleaning your ruby jewelry, use a soft toothbrush, mild liquid soap water, and gently clean. Rinse with warm water right away and dry with a lint-free cloth.
    •       Ruby jewelry can also be cleaned with ultrasonic and steam cleaners, but make sure they are compatible with the metal your ruby is set in.
     
    Follow these guidelines to keep your Natural Ruby jewelry gleaming for the coming years.
