One way is to perform a streak test by rubbing a bit of the stone on an unglazed white porcelain plate, known as a streak plate. A streak of color created by rubbing the stone across the plate is one indication of sapphire authenticity.
Additionally, sapphires are often composed of different minerals that can be identified through an absorbance spectroscopy examination. Another popular practice is known as the breath test, which involves observing the breath fog test.
Hold the stone in front of your mouth, breath deep, and observe the fogging of the stone. The fog will disperse much quicker if the stone contains glass or plastic. To further test a stone’s authenticity, it can be placed in a cup of water and observed for minute bubbles.
If the stone is real, no bubbles will appear, as the water becomes displaced by the stone’s vacuum. Lastly, examining the stone under a magnifying glas will also provide evidence towards authenticity.
Inclusions, or flaws within the stone, are a sure sign of a real sapphire.

What does a fake sapphire look like?
Fake sapphires come in a variety of shapes, sizes, and colors. They may look similar to real sapphires, but can usually be identified by looking for key differences. Firstly, most fake sapphires are not as clear and brilliant as a genuine sapphire.
Fake sapphires may have a dull or cloudy appearance, as well as a lack of transparency or clarity. Additionally, it is common to find fake sapphires with a grey, blue, or purple hue that is not as deep as the hues on a real sapphire.
The carat weight and size of a sapphire can also be clues to authenticity. Fake sapphires will usually have a weight that does not match the size of the stone, making it appear larger than it really is.
Lastly, if the facet cuts on a sapphire are too perfect and uniform, it is likely a fake. Real sapphires will have inconsistencies in their cutting even when they are professionally cut and polished.
Can you tell the difference between lab created and natural sapphire?
Yes, there are physical and chemical differences between natural and lab created sapphires. Natural sapphires are mined from the ground and have been formed by the forces of nature over time. Lab created sapphires, on the other hand, are created in a laboratory under controlled conditions.
Natural sapphires are composed of the mineral known as corundum, as well as traces of other elements. Lab created sapphires also contain corundum, but typically have higher concentrations of certain trace elements, often including titanium, iron, and chromium.
The presence of these additional elements can be detected using spectrometric analyses, which measure the colors and light waves the stone emits.
Furthermore, the size of sapphires can differ between natural and lab created. Natural sapphires may be larger than lab created sapphires due to their longer formation time—in some cases, natural sapphires can take up to thousands of years to form fully.
In comparison, laboratory created sapphires can be made in as little as a few weeks. Despite these differences, lab created stones possess the same beauty and permanency as natural sapphires, making them a great option for those looking for a sapphire of a specific cut and color.
Do real sapphires sparkle?
Yes, real sapphires sparkle! Sapphires are highly sought-after gems because of their deep, beautiful colours including blue, green and yellow. They get their sparkle from how light reflects off their internal facets.
Sapphires are typically faceted with the same cuts as diamonds, and when those facets are cut precisely and the sapphire is placed in the light, it emits a beautiful sparkle. Sapphires can have an even higher sparkle since they provide more return of light than a diamond.
Additionally, different sapphires are cut differently, so one cut will have a different sparkling effect than another cut. Regardless of the cut, sapphires possess a brilliant beauty with their sparkle.
What color sapphire is most valuable?
The most valuable color sapphire is normally considered to be blue sapphire. Blue sapphires are typically available in a range of shades from light blue to dark blue and this color variation also affects their value.
The most valuable blue sapphires are of intense or velvety blue color with a hint of purple. Truly fortunate are the ones who can find a vivid blue sapphire with a vivid royal blue hue, as those stones are generally more expensive than lighter shades.
In addition to its color, clarity, cut, and carat weight, saturation of color is also an important factor in assessing the value of a blue sapphire. Generally speaking, the more intense the color and less visible imperfections, the more expensive the stone.
Other secondary colors of sapphires, such as pink, yellow, green, purple, and orange, are usually cheaper than blue varieties and typically have less complicated pricing structures.
How do you test blue sapphire before wearing?
Before wearing a blue sapphire, you can test its authenticity by looking at its color and clarity. Authentic blue sapphires should have a deep, vivid blue color. You can also assess the cut of the stone to make sure that it is symmetrical and the facets are all even.
Additionally, you can use a 10x magnifying loop to inspect the inclusions in the stone and look for any imperfections or discoloration that could indicate the sapphire is a fake. Another important test in determining the sapphire’s authenticity is to perform a specific gravity test.
You can also take your sapphire to a jeweler to have them perform a refractive index test to make sure that it is a genuine sapphire. Lastly, you should always request a documentation from a certified gemologist that documents the four Cs of the sapphire (color, clarity, cut, and carat weight) and has the gemstone signature to guarantee that your sapphire is genuine.
What is the rarest color of sapphire?
The rarest color of sapphire is one known as “padparadscha”. Padparadscha sapphires can be found in a range of soft shades of pink, orange and yellow, and are extremely rare and expensive. While some sources refer to the ‘rarest’ color of sapphire as being “blue”, this is not strictly accurate, as sapphires can occur in a wide range of blues, from delicate pastels to deep navy.
Padparadscha sapphires, however, are much rarer than blue sapphires and consequently more expensive, making them the rarest color of the gemstone. Additionally, it is important to keep in mind that the value and rarity of sapphires is dependent on more than just the color.
Factors such as size, weight, transparency and clarity all affect the value of sapphires, with clarity and transparency being particularly important.
Will a real sapphire scratch?
Yes, a real sapphire will scratch. Sapphires, like other gemstones, are measured on the Mohs Hardness Scale, and they rate between 9 and 9. 5 on the scale. This means they are quite hard and can withstand plenty of wear and tear, but they are not invincible.
Common household materials such as glass, steel, or even other gemstones can put enough pressure on the sapphire to damage its surface. With the right tools, a sapphire can be cut, shaped, and polished, but it will always be susceptible to scratches and other signs of wear.
With proper care and maintenance, however, a sapphire can last for many years.
Are lab created sapphires as good as natural sapphires?
The quality between a lab created sapphire and a naturally mined sapphire is a highly debated topic. Generally speaking, both lab created and natural sapphires possess many of the same characteristics, including hardness on the Mohs scale, specific gravity, and chemical makeup.
However, when it comes to appearance, there are some differences. Natural sapphires are typically worth more than lab created sapphires because they often exhibit more natural inclusions and color variations than those produced in a lab.
When examining both lab created and natural sapphires side-by-side, it is often difficult for an untrained eye to determine which stone is the more valuable. Therefore, the best way to determine which stone is worth more is to have a gemologist evaluate and certify both stones.
A gemologist can provide a comprehensive report including the stones’ authenticity, grade, and characteristics.
In conclusion, while both lab created and natural sapphires possess all the same characteristics, it can be difficult to determine which stone is of higher quality without consulting a professional. Therefore, if you’re considering purchasing a sapphire, it is best to get a professional evaluation first.
How do you identify natural gemstones?
Natural gemstones can be identified using a few different methods, such as visual inspection, specific tests and gemological laboratory analysis. Visual inspection involves examining the stone up close with a loupe and looking for telltale signs of a natural gemstone, such as inclusions, facets, and texture.
Certain specific tests may be employed in order to identify natural gemstones, such as specific gravity, refractive index and absorption spectrum tests. Gemological laboratories are usually the most reliable way to identify natural gemstones, since they have access to the most sophisticated technological instruments and are staffed with knowledgeable, expert gemologists.
Gemological laboratory analysis typically involves an examination of the physical characteristics of the stone, such as its color, clarity, and cut as well as a chemical test of the stone’s composition.
In some cases a gemological laboratory may also conduct a lab-created or enhanced analysis in order to determine if a stone has been artificially enhanced or modified.
Are lab created gems worth anything?
Lab created gems are worth something and the value depends on a variety of factors, such as the type of gem, the quality of the gem, and the current market value of the gem. It is important to note that lab created gems are not naturally occurring and lack the beauty, rarity, and novelty of naturally occurring gems, which are typically organic material.
Because of this, lab created gems often have lower retail prices than naturally occurring gems. However, some lab created gems can be of high quality and be worth more than naturally occurring ones. Lab created diamonds, for instance, can be harder and of higher quality than even mined diamonds and, therefore, can be worth more.
Ultimately, the value of a gemstone, whether lab created or a naturally occurring mineral, relies on its quality, type, and the current market value.
