  Using state-of-the-art instruments such as spectrometers, microscopes, and laser scanners, we analyze the internal and external characteristics of each diamond to detect inclusions, treatments, or enhancements.

  With increasing availability of lab-grown diamonds, our service includes verification of whether a diamond is natural, synthetic, or treated—vital information for both personal and commercial purposes.
• Light Performance Assessment:
  We evaluate how your diamond reflects and refracts light, giving insight into its brilliance, fire, and scintillation—key indicators of beauty and craftsmanship.
