How to Tell if a Pink Sapphire Is Real

If you want to tell whether a pink sapphire is real, you first must decide what you mean by "real." If you want to determine whether the stone is a piece of glass masquerading as a sapphire, you may be able to tell this by examining the stone yourself. If you're trying to tell the difference between a lab-created or synthetic sapphire and a natural sapphire mined from the Earth, you're best off taking it to a professional. [1]

Examining the Stone

  1. Perhaps the easiest way to tell the difference between a natural sapphire and a synthetic sapphire is to look at the overall quality of the gemstone. A synthetic sapphire should be nearly perfect. [2]
    • Natural sapphires typically have flaws because while growing they were exposed to the elements. Since synthetic or lab-created sapphires grew in a controlled environment, they are more likely to be flawless or near-flawless.
    • A near-flawless natural sapphire would command a significant price regardless of the size. Synthetic sapphires typically will be more affordable, better quality gemstones.
  2. Natural pink sapphires are rare, and are cut differently from other gemstones. Jewelers typically cut stones to calibrated sizes (one carat, two carats, and so on), but pink sapphires over a half carat are cut to accentuate the stone rather than to a specific weight. [3]
    • Stones larger than a carat typically are more likely to be synthetic stones, especially if they cost less than a natural stone of that size would cost.
    • Most natural sapphires are cut using a mixed cut, rather than cut to specific shapes like other natural stones.

  3. If the pink sapphire is real, it will have a gemstone report that details the origin of the stone and any treatments that have been done to it. Check watermarks for proof of the authenticity of the report. [4]
    • Pink sapphires may be heat-treated to bring out their natural color. Some people don't consider treated gemstones to be "natural," and if the gemstone has been treated in any way this must be disclosed on the gemstone report.
    • The report should have an ID or reference number on it. Call the company that issued the report and give them the reference number to confirm the report's validity.
  4. How a pink sapphire comes to your attention may provide clues as to whether it's real. Think about how trustworthy the person is who introduced you to the sapphire, as well as their background and expertise. [5]
    • If you're looking at a pink sapphire at an established jewelry store, you can be fairly confident that it is what they say it is. However, be cautious with less reputable dealers.
    • Pawn shops may incorrectly label a synthetic sapphire as a natural sapphire, since it can be difficult to tell them apart. Pawn shops also typically sell gemstones "as is" and make no guarantees about their authenticity.

Getting Professional Testing

  1. Especially if the pink sapphire is a significant purchase, get it independently certified with a fresh gemstone report. The laboratory will examine the sapphire to determine whether it's natural. [6]
    • An independent gemstone certification typically will cost you a few hundred dollars.
    • If the gemstone report you get conflicts with any other reports you have, you may want to get a third or even fourth opinion, particularly if the stone represents a significant investment.
  2. The spectroscope uses fiber-optic lighting to reveal details about the color of the stone that can indicate if the pink sapphire is synthetic or natural.
    • Certain color flaws or differentiations are created by the interaction between the natural stone and other minerals in the earth, such as iron.
    • Synthetic sapphires typically have coloring agents that will appear bright and shiny under fiber-optic lighting compared to natural sapphires.
  3. Some gemstone laboratories use a complex system that detects the stone's emission of X-ray fluorescence. This advanced testing method can be used to distinguish synthetic and natural gems. [7]
    • Use of this system also can identify trace minerals and elements in a natural stone, which could help pinpoint where the stone was mined.
  4. A UV test can help identify the geographic origin of a natural pink sapphire, and also can help detect whether the sapphire is synthetic. [8]
    • UV tests also reveal whether the stone has been treated or enhanced.

    The only surefire way is to make sure that it has a lab report, or to get it tested by an accredited gem lab or a certified appraiser who has a gemology degree. Sapphires and diamonds have a different refractive index and hardness level, but it's hard for the consumer to test those factors.

    There are many other gemstones that are pink. For instance, garnet, morganite, tourmaline, spinel, kunzite, diamond and more! When pink sapphire tips over into a darker hue, this gemstone is classified as ruby. So, there are pink rubies too! In addition, there are other natural stones on the market that have colour-changing abilities, depending on the lighting present. For example, diaspore is a green-yellow stone, but under incandescent lighting, the stone's colour changes to an orange-pink!
