For most of us, sapphire is the very first gemstone that comes to mind when we think of colored stones. It is immediately associated with a deep, intense blue—often overlooking the fact that it actually exists in a wide array of hues: pink, yellow, teal…
At Gemmyo, we have chosen to highlight one of its most distinctive variations: the green sapphire, which we have named the olive green sapphire. A name inspired by the softness of its hue, reminiscent of the landscapes of Provence and its olive groves.
But what makes the green sapphire so unique?
A legitimate question we will explore throughout this guide. But first, let us look back at the history and origins of this striking green-hued gemstone.
The History of the Green Sapphire
The name “sapphire,” derived from the Greek Sappheiros, meaning blue, now encompasses the full range of hues displayed by this precious gemstone. Its use in trade dates back to ancient times: stones from Sri Lanka were already being used by the Romans as early as the 5th century BCE, adorning both jewelry and sumptuous decorative objects.
For the Persians, its color evoked the reflections of the sky. Later, monarchs and the Catholic Church adopted it, incorporating it into fine jewelry as a symbol of purity and a connection to the divine.
Rare and highly prized by ancient civilizations, it became more accessible following the discovery of numerous deposits in Australia, Thailand, India, and Africa.
Historical sources make little explicit mention of green sapphire, as precise distinctions between sapphire colors were not yet established. It was only from the 19th century onwards that the different shades began to be identified. Long overlooked, green sapphire has experienced renewed interest since the 2000s, thanks to advances in modern gemmology.
Anecdote: In 1938, miner Frederick Max Stonebridge discovered a 202-carat green sapphire in Queensland, Australia—a true giant, roughly the size of a golf ball. After a remarkable journey marked by thefts, sales, and restitutions, the stone eventually returned to its country of origin. Today, it resides in the prestigious Richardson family collection.
Origins of the Green Sapphire
Green sapphire is found in several locations around the world. The most renowned deposits are in Australia, particularly in Queensland, New South Wales, and Western Australia. It is also found in India, notably in Jammu and Kashmir and Karnataka, as well as in Africa—in Tanzania, Kenya, Malawi, and Madagascar, from where Gemmyo sources its green sapphires.
It is worth noting that a sapphire’s color varies depending on its geographical origin. For instance, Australian green sapphires tend to display lighter tones, while those from Thailand exhibit deeper shades of green.
Characteristics of the Green Sapphire
At Gemmyo, the green sapphire is distinguished by its soft, spring-like olive green hue. A luminous, summery color that captivates with its radiant reflections. Yet its true uniqueness lies in its shifting, mesmerizing nuances.
Gemmyo’s advice: As the shades of green sapphire evolve with light and angle, we highly recommend viewing it in-store to fully appreciate its chromatic richness.
1. A soft and luminous hue
Its distinctive green color is due to the presence of iron oxide in its composition. At Gemmyo, we have selected an olive green sapphire with delicate, spring-like nuances. Luminous and rare in its natural color, it charms through its subtlety.
Less intense than emerald, it nonetheless radiates with quiet brilliance. Green sapphire brings a sense of freshness and serene elegance—qualities highly valued in contemporary jewelry. It evokes the landscapes of southern Provence, with olive groves bathed in golden light: a simple, natural, and timeless beauty.
2. Exceptional hardness
Sapphire is the hardest of colored gemstones, ranking 9 out of 10 on the Mohs scale. By comparison, other green gemstones such as emerald and tsavorite display lower hardness levels, ranging respectively from 7.5 to 8 and from 7 to 7.5.
3. Remarkable heat resistance
Green sapphire belongs to the corundum family, like all sapphires. These gemstones are highly resistant to thermal shock and high temperatures, with a melting point of around 2000°C—a level you are unlikely to encounter.
In practical terms, wearing a sapphire means you need not worry about everyday heat exposure—unlike emerald, for instance.
Beyond these properties, sapphire is also renowned for its exceptional quality. But how is this defined?
Quality Grades
Unlike diamonds, colored gemstones do not benefit from standardized, internationally recognized grading systems.
That said, the certification of a colored gemstone—such as sapphire—is just as rigorous and generally corresponds to three levels of quality:
- A: average, commonly available quality
- AA: a rarer quality, typically used by small local lapidaries rather than large retailers; it denotes superior stones with minimal inclusions and vivid color
- AAA: the highest possible quality for colored gemstones; it signifies flawless stones with exceptional brilliance and rich, even color
At Gemmyo, all our colored gemstones—including green sapphires—are certified AAA. This certification by our gemmologists guarantees a gemstone of outstanding quality, expertly cut and among the finest available.
How is sapphire quality assessed?
It draws directly from the universal “4Cs” used in diamond grading:
- Color: whether natural or enhanced
- Carat weight: the stone’s weight
- Cut: the quality of faceting and overall shape
- Clarity: the presence or absence of inclusions visible to the naked eye or under 10x magnification
Frequently Asked Questions
Are green sapphires treated?
The vast majority of natural colored gemstones are heat-treated.
Heating is a long-established process used to stabilize or enhance a gemstone’s color and improve its durability. Far from harming the stone, it is widely considered beneficial.
Contrary to popular belief, untreated stones are extremely rare. Unless explicitly stated and supported by certification from an independent laboratory, it is unlikely that a gemstone is unheated. Stones with intense color that are entirely untreated are exceptionally rare and typically reserved for high jewelry and one-of-a-kind pieces.
It is important not to confuse heat treatment with chemical treatments—such as irradiation, fracture filling, impregnation, or dyeing—which are regulated and may alter the nature of the stone. Gemmyo sapphires are heat-treated—a natural and accepted process—but we carefully control our stones to avoid any other forms of treatment.
Are green sapphires rare?
Natural green sapphires are far less common than blue, pink, or yellow sapphires, making them particularly sought after in fine jewelry. Their range of shades—from soft green to deep tones—further enhances their unique and exceptional character.
Tsavorite, Emerald, or Green Sapphire: which should you choose?
While all three share a green hue, they differ in several key aspects.
Tsavorite displays a vivid, vibrant green, while emerald captivates with its deep, magnetic tone marked by natural inclusions.
By contrast, Gemmyo’s green sapphire reveals a softer, more luminous olive green.
Another essential distinction lies in hardness. Tsavorite ranges from 7 to 7.5 on the Mohs scale, and emerald from 7.5 to 8. Green sapphire, more resistant, reaches 9. As such, tsavorite and emerald are more delicate and require special care, whereas green sapphire is more robust and better suited to everyday wear.
Ultimately, the choice is yours—guided by the hue you prefer, the symbolism it evokes, and how you wish to wear it.
Can sapphires be certified by an international body?
Yes, a sapphire—like all colored gemstones—can be certified by an international laboratory such as the GIA (Gemological Institute of America). However, this remains relatively uncommon.
Certification by such laboratories is costly—up to $500 per stone—and significantly impacts the final price.
To ensure fair pricing, and like most major jewelry houses, Gemmyo chooses to certify its gemstones through its own expert gemmologists.

Which metal best complements a green sapphire?
Green sapphire pairs beautifully with yellow gold, creating a soft and warm effect. For a more contemporary look, rose gold is an ideal choice. Cooler tones such as white gold are best avoided, as they may diminish the stone’s natural luminosity.
For what occasion should a green sapphire be given?
Often chosen for engagements, sapphire is also traditionally gifted for the 5th and 16th wedding anniversaries.
It is equally suited to many occasions: celebrating enduring love, a new beginning, or a personality drawn to a distinctive gemstone that blends symbolism with modernity.
With its fresh, spring-like hue, green sapphire is an ideal alternative for engagement rings. Both unique and delicate, it enchants with its subtle softness and luminous brilliance.
