Simple steps to gem authenticity

Step 1: initial consultation

Begin your journey with Legacy Gem Certification by scheduling an initial consultation. Our experts will discuss your specific needs, whether you are a collector, dealer, or managing an estate. This crucial first step allows us to understand the unique characteristics of your gems, uncut stones, or antique jewelry. During the consultation, we will outline the processes involved in diamond grading, lab-grown detection, and museum-grade authentication. This personalized approach ensures that we tailor our services to meet your requirements, providing you with the best possible outcomes.
Step 2: gem evaluation
Receive a comprehensive gem evaluation.
Once the consultation is complete, we will begin the detailed evaluation of your gems. Our gemologists employ advanced techniques for diamond grading and lab-grown detection to ensure accuracy and reliability. Each stone undergoes a meticulous inspection, assessing its quality, clarity, and authenticity. This stage is crucial for collectors and dealers looking to understand the true value of their gems. We document every finding, setting the foundation for certification and appraisal services. Your gems are treated with the utmost care, ensuring all evaluations are precise and thorough.
Step 3: certification process
Obtain your official certification.
After the evaluation, we initiate the certification process. This involves compiling all findings into an official certificate that outlines the gem's characteristics, including its grade and authenticity. Our certificates meet stringent industry standards, ensuring that your gems are recognized by collectors and dealers alike. This documentation is essential for insurance purposes and future sales. We pride ourselves on delivering certification with integrity, providing you with peace of mind regarding the value and authenticity of your gems.
Step 4: appraisal services
