What are Authentic Gemstones?
Authentic gemstones are naturally occurring minerals that have been cut and polished for use in jewelry and other decorative items. Here are a few key terms to understand:
- Natural Gemstones: These are formed naturally in the earth without any human intervention.
- Synthetic Gemstones: These are created in laboratories and have the same physical and chemical properties as natural stones.
- Treated Gemstones: Natural stones that have been enhanced or treated to improve their appearance.
Knowing these terms will help you make a more informed purchase and understand what you are paying for.
Do Your Homework
Before you even step into a store or browse online, it’s important to educate yourself about the different types of gemstones. Each gemstone has unique characteristics and value.
- Books and Guides: Consider reading books or guides on gemstones. “Gemstones of the World” by Walter Schumann is a highly recommended book.
- Online Resources: Websites like the Gemological Institute of America (GIA) offer extensive information on various gemstones.
- Experts and Forums: Joining online forums or seeking advice from gemstone experts can also be very helpful.
Understanding the basics will give you the confidence to ask the right questions and recognize authentic stones.
How to Identify Real Gemstones
Identifying real gemstones involves a few simple checks you can perform on your own. Here’s a more detailed look at what to consider:
- Color:
- Authentic gemstones have vibrant colors but not excessively bright or uniform. Natural variations in color are common.
- For example, real emeralds usually display a rich, deep green with slight variations and inclusions, rather than a flat, uniform color.
- Compare the stone’s color to reference images of genuine gemstones to spot discrepancies.
- Clarity:
- Real gemstones often have natural inclusions (tiny imperfections or materials trapped inside the gemstone).
- While inclusions are normal, they should not make the stone look cloudy or opaque.
- Completely flawless stones can be synthetic or heavily treated. Use a magnifying glass to inspect the stone for inclusions.
- Cut:
- The quality of the cut can affect the gemstone’s brilliance and appearance.
- A well-cut gemstone will reflect light evenly and enhance its natural beauty.
- Poorly cut stones with uneven facets or dull appearance can indicate synthetic or fake stones.
- Carat Weight:
- Genuine gemstones have specific densities, making them heavier than fake ones of the same size.
- For example, a real diamond will feel heavier than a cubic zirconia of the same size.
- Use a carat scale to weigh the stone and compare it to the standard weight for that type of gemstone.
Tools to Help You Check:
- Magnifying Glass (10x Loupe):
- A 10x loupe is an essential tool for any gemstone buyer. It helps you see inclusions and surface details clearly.
- Look for natural inclusions which can signify authenticity.
- Refractometer:
- This tool measures the refractive index of the gemstone, which is unique to each type of stone.
- Place a small drop of contact liquid on the stone and use the refractometer to get a reading. Compare this reading to known values for the gemstone you are examining.
- Spectroscope:
- A spectroscope can analyze the light spectrum emitted by a gemstone, revealing its unique absorption pattern.
- This pattern helps identify the gemstone and distinguish between natural and synthetic stones.
Practical Tips:
- Use Reference Materials: Carry a gemstone identification book or access online databases while shopping.
- Compare with Certified Stones: If possible, compare the stone with a certified authentic gemstone.
- Professional Appraisal: Consider having the gemstone appraised by a professional gemologist, especially for high-value purchases.
These detailed checks and tools can help you confidently identify real gemstones, ensuring that you are getting value for your money.
Certification is Key
When buying gemstones, always ask for a certificate of authenticity from a reputable certification body. Certification provides assurance that the gemstone has been evaluated for its quality and authenticity by professionals.
Why Certification Matters
- Verification of Authenticity: Certificates confirm that the gemstone is natural, synthetic, or treated, providing a clear understanding of what you are purchasing.
- Quality Assurance: Certification bodies evaluate various aspects of the gemstone, such as color, clarity, cut, and carat weight, ensuring you get what you pay for.
- Market Value: Certified gemstones often have higher resale value and are more trusted by buyers and sellers alike.
Trusted Certification Bodies
Here are some well-known certification bodies that are recognized for their rigorous standards:
- Gemological Institute of America (GIA): One of the most reputable organizations, GIA provides detailed reports on diamonds and colored gemstones.
- American Gem Society (AGS): Known for its strict grading standards, AGS offers certificates primarily for diamonds.
- International Gemological Institute (IGI): IGI certifies a wide range of gemstones and jewelry, making it a popular choice for many buyers.
Understanding a Gemstone Report
A gemstone report typically includes the following details:
- Type of Gemstone: Specifies whether the gemstone is natural, synthetic, or treated.
- Carat Weight: The weight of the gemstone.
- Dimensions: The physical size of the gemstone.
- Color and Clarity Grades: Evaluation of the gemstone’s color and clarity.
- Cut Grade: The quality of the gemstone’s cut.
- Treatments: Any enhancements or treatments the gemstone has undergone.
When you receive a certificate, take the time to read and understand it. Verify the information against the gemstone you are purchasing to ensure it matches.
Practical Tips
- Ask for Certification: Always request a certificate from the seller. If they cannot provide one, consider it a red flag.
- Verify the Certificate: Use the certification body’s online database to verify the authenticity of the certificate.
- Consult a Gemologist: If you are unsure about the certificate or the gemstone, consult a professional gemologist for a second opinion.
Having a certified gemstone provides peace of mind and ensures that you are making a wise investment.
Finding a Trustworthy Seller
Choosing the right seller is crucial when buying authentic gemstones. A reputable seller will provide quality products, transparency, and excellent customer service. Here are some tips to help you find a trustworthy seller:
Characteristics of a Good Gemstone Seller
- Reputation: Look for sellers with a strong reputation in the market. Check online reviews, testimonials, and ratings on platforms like Google, Yelp, or specialized gemstone forums.
- Experience: Sellers with many years of experience are generally more reliable. They have established their business and built trust over time.
- Transparency: A good seller will be open about the origin, treatment, and certification of their gemstones. They should willingly provide all necessary information and answer your questions.
Questions to Ask the Seller
- Is the gemstone natural, synthetic, or treated?: This helps you understand what you are purchasing.
- Can I see the certificate?: Always ask for a certificate from a reputable certification body.
- What is your return policy?: A trustworthy seller will have a clear and fair return policy in case you are not satisfied with your purchase.
Buying Online vs. In-Store
