Unlocking the Mysteries of Gemstones: Essential Uses of a FABLE Gem refractometer

A gemstone refractometer is an essential tool in the field of gemology for accurately identifying and distinguishing between various types of gemstones. Below are several scenarios where a FABLE gemstone refractometer can be invaluable:

Identify Unknown Gemstones

When you come across a beautiful gemstone and want to determine its type, you can use a FABLE gemstone refractometer to measure its refractive index. By comparing the obtained refractive index with a reference table, you can identify the gemstone. For example, if you measure the refractive index of a blue gemstone and find it to be between 1.762 and 1.770, you can conclude that the gemstone is a sapphire.

Distinguish Similar Gemstones

When faced with a batch of red gemstones that could include ruby, red glass, red spinel, red tourmaline, red scapolite, red garnet, etc., they may appear visually similar. To distinguish them, you can use a FABLE refractometer to measure their refractive indices. Here are the refractive indices for some common red gemstones:

Ruby: 1.762-1.770
Red Tourmaline: 1.624-1.644
Red Spinel: 1.718
Red Scapolite: 1.550-1.564
Red Garnet: 1.714-1.743
Red Glass: 1.4-1.7

Name Ruby red tourmaline red spinel  red scapolite Red   garnet Red glass
Refractive index 1.762-1.770 1.624-1.644 1.718 1.550-1.564 1.714-1.743 1.4-1.7

 

Purchase Gemstones

When purchasing gemstones at a market, bringing along a FABLE gemstone refractometer can help you avoid fakes. The refractometer is small, light, and portable, making it convenient for on-the-spot testing. This can prevent you from inadvertently buying counterfeit gems.

Help Friends Identify Gems

If your friends have gemstones they can’t identify, you can assist them by determining the type of gemstone using a FABLE refractometer. This service can enhance your friendship, provide valuable experience, and potentially earn you a fee.

Outdoor Treasure Hunting

During outdoor treasure hunting or gem digging, once you find gemstones, you can polish them and then use a FABLE refractometer to measure their refractive index to determine their type. This can be particularly useful when sifting through river sediments or mountain finds.

Academic Research and Education

In academic settings, FABLE gem refractometers are often used in geology and gemology courses. Students and researchers can use these devices to study and identify various gemstones, helping them understand the physical properties and characteristics of different minerals.

Jewelry Appraisal

Professional appraisers often use FABLE refractometers to authenticate and value gemstones in jewelry. By accurately identifying the gemstones, appraisers can provide precise valuations, ensuring fair transactions in the jewelry market.

Quality Control in Gemstone Cutting

In gemstone cutting workshops, FABLE refractometers can be used to verify the type of gemstones being processed. This ensures that the correct procedures are followed for different types of gemstones, preserving their quality and value during the cutting and polishing stages.

Gemstone Collection and Curation

Gem collectors and curators can use FABLE refractometers to catalog and verify their collections. This ensures that each gemstone is correctly identified and documented, preserving the integrity and value of the collection.

Trade Shows and Exhibitions

At gem and jewelry trade shows or exhibitions, vendors can use FABLE refractometers to demonstrate the authenticity and quality of their gemstones to potential buyers. This adds credibility and can facilitate sales by providing on-the-spot verification.

Limitations of Gemstone Refractometers

However, not all gemstones can be tested using a refractometer. Here are some exceptions:

Gemstones with Unpolished Surfaces: Refractometers require a polished surface to accurately measure the refractive index.
Gemstones with a Refractive Index Greater than 1.785: Such as diamonds and cubic zirconia (CZ), which exceed the refractometer’s measuring range.
Organic Gemstones: Including pearls, amber, and coral, which do not have the crystalline structure necessary for refractometer testing.
Conclusion

A FABLE gemstone refractometer is a versatile and indispensable tool for gemologists, jewelers, appraisers, collectors, and enthusiasts. By measuring the refractive index, it provides a reliable method for identifying and distinguishing between various gemstones in a variety of settings, from marketplaces to educational institutions. However, users should be aware of its limitations and ensure that the gemstones are suitable for refractometer testing.
