With the rising popularity of lab grown diamonds, many buyers are eager to understand how to identify them. While lab grown diamonds are real diamonds with the same chemical and physical properties as natural ones, distinguishing between the two can be important for transparency, valuation, and personal preference. This article offers practical tips for buyers on how to spot a lab grown diamond and what to look out for during the purchasing process.
Understanding What Lab Grown Diamonds Are
Lab grown diamonds are created in controlled laboratory environments using advanced technology that replicates natural diamond formation. They have identical chemical composition, hardness, and brilliance as mined diamonds. Because of this, spotting them visually is almost impossible without specialized equipment.
Tip 1: Check for Certification
One of the easiest ways to identify a lab grown diamond is to look for certification from reputable gemological labs. Certificates from organizations like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI) will specify whether a diamond is lab grown or natural. Always request to see a certificate before purchasing.
Tip 2: Use a Diamond Tester with Advanced Capabilities
Standard diamond testers measure thermal conductivity, which lab grown and natural diamonds share. However, advanced testers designed to detect growth patterns and inclusions specific to lab grown diamonds can help differentiate the two. These tools are typically used by jewelers and gemologists.
Tip 3: Examine Inclusions and Growth Patterns Under Magnification
Lab grown diamonds may exhibit distinct inclusions and growth structures different from natural diamonds. For example, metallic inclusions or specific patterns caused by the manufacturing process can be clues. A jeweler’s loupe or microscope can reveal these features.
Tip 4: Ask About the Diamond’s Origin
Reputable sellers will disclose whether the diamond is lab grown or natural. Transparency is key in ethical buying. Don’t hesitate to ask directly about the diamond’s origin and request supporting documentation.
Tip 5: Price Comparison as an Indicator
Lab grown diamonds are generally priced 20-40% lower than comparable natural diamonds. If a deal seems too good to be true for a natural diamond, it might be a lab grown stone or a misrepresented product.
Tip 6: Use UV Light to Detect Fluorescence
Some lab grown diamonds exhibit different fluorescence patterns under UV light compared to natural diamonds. While not definitive alone, UV light testing can be an additional method used by experts.
Conclusion
Spotting a lab grown diamond requires a combination of knowledge, trusted certification, and sometimes specialized equipment. Buyers should prioritize transparency and documentation to ensure they know exactly what they are purchasing. Whether choosing lab grown or natural diamonds, being informed helps you make a confident and satisfying decision.
