Precious Green Gemstones

In the jewelry world, only 4 gemstones are recognized as truly “precious”: Diamond, Ruby, Sapphire, and Emerald. These 4 gems are precious because they are very rare, very durable, beautiful, and have historical significance.

Green Diamonds

When most people think of diamonds, they imagine sparkling white stones. Did you know, however, that diamonds actually come in a rainbow of colors? These are called Fancy Colored Diamonds and they are highly sought-after. What makes fancy-colored diamonds different from colorless diamonds is the presence of trace elements that create beautiful hues. While colorless diamonds are valued for their lack of color, fancy-colored diamonds are cherished for their intense tones.

Today, we are focusing on green diamonds, which earn their place among the world’s most precious green gemstones. Green diamonds are among the rarest. They form deep underground over millions of years when natural radiation changes a diamond’s structure, creating their green color. While natural green diamonds are rare and valuable, treated green diamonds are highly prized and expensive.

There’s nothing wrong with treated green diamonds - they are still genuine diamonds that are enhanced to achieve their green color. Even smaller, treated green diamonds fetch tens of thousands of dollars per carat. Whether natural or treated, green diamonds come with special certificates from credible gem labs like GIA. These reports verify their authenticity and disclose any treatments.

Emeralds

Emeralds have been treasured for millennia. These beautiful green gemstones form when beryl mixes with chromium or vanadium deep within the Earth. The best emeralds come from Colombia, particularly in the Muzo region. There are also very yieldful emerald deposits in Zambia and Brazil. Unlike other precious stones, emeralds almost always have small inclusions or tiny cracks inside them. These are called ”jardin” because they look like little plants under a microscope. These inclusions are totally normal and help prove the emerald is real.

Most emeralds are treated with resin or oil to improve their appearance and clarity. Emeralds are graded by color intensity: Vivid Green, being the most valuable, Green - showing a good color saturation, and Light Green, having a more subtle, paler color. Emeralds rank 7.5-8 on the Mohs scale, behind sapphires and diamonds. This means they need extra care. They can crack or chip if hit hard.

Green Sapphires

Most people think of blue when they hear “sapphire”. These precious gems come in many colors, including beautiful pinks and greens. Green sapphires get their color from iron and titanium present in the stone. Green sapphires are harder than emeralds. This means they are perfect for all types of jewelry. The best green sapphires come from Sri Lanka, Australia, and Montana.

An accepted practice in the gem world is to heat them to improve their color. Heat treatment doesn’t make the stone less valuable. Green sapphires cost much less than emeralds of similar quality and size. They are a smart choice for people who want a precious green gem without breaking the bank.

Green Sapphire

Semi-Precious Green Gemstones

Semi-precious gemstones offer great beauty at more affordable prices than precious gemstones. These gemstones are not as rare as green diamonds or emeralds. They can, however, be just as stunning in jewelry. Semi-precious gemstones are gems that are not categorized as one of the four traditional “precious” stones (diamond, ruby, sapphire, and emerald). They encompass a host of minerals, crystals, and even some organic materials, valued for their color, beauty, and unique properties.

It is also believed by some cultures to protect its wearers from nightmares. Most peridot today comes from Arizona, though it can be found in Myanmar and Pakistan. Not as rare as emeralds and other precious stones, it is a more affordable option. Peridot is softer than many other gemstones; it requires gentle care.

Chrome Diopside

Chrome diopside is not as popular as other green gems, but it is known for its vivid green color. This bright green is just as intense as that of emeralds, but it costs much less. This gem is mined almost exclusively in a region of Eastern Siberia called Inagli. This area is also famed for impressive diamond deposits. This makes it rare, but not as expensive as other rare gems. The downside of chrome diopside is that it is soft and can scratch easily. Due to this, chrome diopside is often cut into smooth, rounded shapes rather than faceted stones.

Jade

This is a particularly meaningful stone. In China, it’s been treasured for over 5,000 years. People believe it brings protection and luck to its wearers. Now, there are actually two different minerals called jade: Jadeite and Nephrite. Jadeite is rarer and more valuable. The finest jadeite has a pure green color and is nearly transparent. Most jadeite comes from Myanmar ( Burma). It can be found in Guatemala and other parts. The ideal jadeite stone has an even green color with no patches or streaks. Imperial Jadeite is among the most expensive gemstones in the world, with top pieces selling for millions of dollars per carat. The most prized jadeite comes from Myanmar and displays a deep green color with great transparency that commands astronomical prices at auction. Jade is quite tough and durable.

Other Beautiful Green Gemstones

So, aside from semi-precious and precious stones, other beautiful green gemstones deserve attention. These are usually more affordable and not as rare. They are great choices for daily jewelry or for people starting to collect gemstones.

Green Aventurine

Green aventurine is a type of quartz that has a sparkly effect called aventuresence. This sparkle comes from small pieces of mica inside the stone that reflect light. Most people recognize aventurine by its milky green color and light shimmer. It is much lighter in color than most green gemstones, giving it a calm appearance. Some people believe aventurine brings prosperity and good fortune. This belief has made it popular in spiritual practices. Now, aventurine is a variation of quartz: it is quite durable and hard.

Malachite

Malachite is a very recognizable stone due to its color and unique banded patterns. These bands create swirling designs that look like water ripples or tree rings. This gemstone is formed from copper deposits. In Ancient Egypt, it was ground into powder to make green eye makeup! It has been used for decorations for thousands of years. Malachite is quite soft compared to other gemstones and requires gentle handling. It is not suitable for bracelets or rings that can get bumped around. The stone’s beautiful patterns make each piece unique.

Green Agate

Green agate is a variety of chalceony that comes in different shades of green. Some pieces are natural, while others are dyed to create deeper colors. Natural green agate usually has a softer green color. Dyed agate can be bright and intense. There’s nothing wrong with dyed agate as long as it is properly labeled. Agate often forms in beautiful patterns, including stripes, bands or moss-like inclusions. Agate is actually quite durable and works for all types of jewelry.

Choosing the Right Green Gemstone

So with so many green gems to choose from, picking the right one can be a bit of a task. Green gemstones range from very budget-friendly to extremely expensive. Set a realistic budget before shopping. For budget-conscious buyers, consider green agate or aventurine. These stones offer beautiful green colors without the high price tag. If you have a medium budget, your best bets are jade, peridot or green tourmaline. As we have already laid out, green gems come in a host of different shades. Some people prefer green colors, while others like greens with other secondary colors. The most classic green color is provided by the emerald. Peridot has a unique yellow-green shade. Tsavorite garnet provides a brilliant green sparkle, and chrome diopside offers an intense green.

Consider your daily activities and how they can affect your jewelry. If you work a lot with your hands, cook frequently, or play sports, select more durable stones and potential settings. Some stones need special care. Ultrasonic cleaners can damage emeralds. Malachite shouldn’t get wet for long periods. Ask for help from jewelry experts. They can explain the distinctions between stones, help you understand treatments, and suggest the best options for your needs. A good jeweler will also help you choose the right setting and metal for your green gemstones.

Caring for Your Green Gemstones

Taking care of your green gemstones will keep them beautiful for years to come. Most green gemstones can be cleaned safely with a warm, mild soap solution. Use a soft toothbrush to gently scrub away oils and dirt. Never use harsh abrasives, bleach, or chemicals on your gemstones. Avoid ultrasonic cleaners unless you are sure the stone can handle them. Clean your green gemstone jewelry regularly to prevent the buildup of lotions, grease, and dirt.

  • Malachite - This stone should not be soaked in water for long periods. Clean it with a damp cloth and pat dry immediately.
  • Emerald - Emeralds should not be cleaned in ultrasonic cleaners, which can cause cracks and color shifts.
  • Jade - Jade is a tough gem, but it can be damaged by harsh chemicals.
  • Peridot - Peridot can also be scratched easily.

Store your green gemstone jewelry in a way that prevents damage and scratches. Harder stones like green sapphire and tsavorite can scratch softer stones like peridot. Do not put all your jewelry together in one box. Keep your jewelry away from extreme temperatures and direct sunlight. Some gemstones can change color or become dull if exposed to too much light or heat. Consider getting a jewelry box with soft, fabric-lined compartments.

When you are engaging in certain activities, take off your green gemstone jewelry. When getting dressed, put your jewelry on last and take if off first when you get home. Have your green gem jewelry professionally inspected and cleaned at least once a year. Professional cleaning can make your gemstone look new again. If you notice any loose stones or cracks, take your jewelry to a professional immediately. Don't try to fix these problems yourself.
