Introduction
Any gemstone is not viewed with only one angle. There are geologists and gemologists who view stones from a very different perspective. They both study the earth and its composition but have a slightly different take on some aspects. Before we get on to knowing how geologists vs. gemologists look at amethyst, we have to learn a little about them as well. Here's how they both work :
Geologist | Gemologist | |
Definition | An academically trained scientist with a strong background in geology—the study of the composition and formation of the Earth and other planetary bodies | A specialist with formal education who is capable of identifying, analyzing, and assessing gemstones, certain rocks, soft minerals, and some organic materials. |
Focus of coursework | Numerous fields are studied by geologists, such as hydrogeology, engineering geology, geochemistry, geophysics, and paleontology. | They focus on mastering gemstone analysis, which also includes amethyst mineral composition. |
Tasks | Geologists look for precious metals, natural gas, and petroleum. They research landslides, tsunamis, volcanoes, and earthquakes. In planetary geology, planetary body sampling and analysis are managed by remote telemetry. | Identification by spectroscopy, inclusions, specific gravity, and refractive index is the main focus of gemologists. |
Tools used | Rock hammer, hand lens, notebooks/clipboard, pencil magnet, small acid bottle, retractable knife or Mohs hardness testing kit, scales, compass, and GPS | Specific gravity testing liquids, Mohs hardness points, ultraviolet (UV) light, and a stereo microscope |
Let's have a look at how they view amethyst differently:
Geologist’s perspective
Amethyst in geology is considered as a mineral, and their primary focus is on its occurrence, formation, and geological context. This is how they study the stone:
- Crystal structure and properties: They examine the stone’s growth patterns and color differences that are brought on by geological circumstances and crystal lattice.
- Formation and Composition: They study how amethyst formation takes place in volcanic rocks, geodes, and hydrothermal veins. They also study its chemical composition.
- Geological environments: They locate amethyst reserves in places like Brazil, Uruguay, and Zambia and research the geological mechanisms that produce them.
- Dating and analysis: They figure out the age and background of amethyst formations using spectroscopic and radiometric dating.
Gemologists perspective
They look at amethyst as a gemstone and focus primarily on its grading, quality, and commercial value. This is how they study the stone:
- Cut and Shape: They examine the ways in which various cuts improve market appeal and brilliance.
- Color and Clarity: They assess the purple color's strength and coherence and look for additions that could compromise transparency.
-
Treatment and Enhancement: They recognize synthetic or heat-treated amethyst and differentiate between lab-made and natural stones.
- Authentication and Valuation: They use instruments such as microscopes, spectrometers, and refractometers to ascertain market value and confirm authenticity.

Frequently Asked Questions
Q: How do geologists explain the purple color of amethyst?
Geologists attribute amethyst's exquisite purple hue to the presence of iron impurities and the effects of natural irradiation during the quartz crystal's formation deep underground.
Q: What qualities do gemologists look for when evaluating amethyst?
Gemologists evaluate several key qualities in amethyst, including color depth, clarity, precision of the cut, and carat weight. They particularly value deep, rich purples with minimal inclusions and high transparency, as these features enhance the stone's beauty.
Q: What do geologists find most fascinating about amethyst?
Geologists are captivated by the formation of amethyst within volcanic geodes. They find its crystal growth patterns, zoning, and interactions with other minerals, such as calcite or hematite, particularly intriguing.
Q: Do gemologists ever use microscopes when examining amethyst?
Absolutely. Gemologists employ microscopic tools to scrutinize inclusions, which play a crucial role in verifying the stone's authenticity, identifying treatments, and determining its geographic origin.
Q: How do geologists use amethyst in field studies or research?
Geologists study amethyst as an indicator of geological environments, such as hydrothermal systems. They use it to gain insights into the mineralization processes within specific rock formations.
Q: What role does crystal structure play in each field's analysis?
The crystal structure is significant in both fields. For geologists, it aids in classifying amethyst as hexagonal quartz. For gemologists, the structure influences how light interacts with the stone, which is essential for assessing its brilliance.
Q: Are inclusions viewed differently by gemologists and geologists?
Gemologists tend to view inclusions as potential flaws or distinctive markers. On the other hand, geologists regard them as valuable indicators that can shed light on the environmental conditions present during the crystal's formation.
Q: What equipment is most essential to each expert when studying amethyst?
Geologists typically rely on tools such as X-ray diffraction, electron microscopes, and various field equipment. In contrast, gemologists use loupes, spectroscopes, and hardness testers to examine and evaluate the gemstones.
