Why Choose Our Diamond Testing Services?

Diamonds are among the most valuable and cherished gemstones. However, with the rise in synthetic and treated stones, knowing the authenticity and quality of your diamond is more important than ever. Our lab combines scientific precision with international grading standards to provide accurate, unbiased evaluations.

Our Diamond Services Include:

✅ Diamond Grading & Certification

We evaluate your diamonds based on the globally recognized 4Cs:

  • Cut – Measures brilliance and sparkle
  • Clarity – Checks for internal and surface inclusions
  • Color – Ranges from colorless to light yellow
  • Carat Weight – Measures the size and weight of the diamond

Each certified diamond comes with a detailed grading report from our lab.

✅ Diamond Quality Checks

Whether you're buying, selling, or appraising, we help you determine the overall quality and market value of your diamonds, giving you confidence and transparency in every transaction.
