Why Certification is Essential

  • A certificate confirms whether a stone is natural, synthetic, or treated.
  • Gemstone price depends on factors like origin, clarity, and treatment. A certified gem is easier to appraise.
  • Uncertified gems may be misrepresented, leading to overpayment for lower-quality stones.
  • Certified gemstones have documented proof of authenticity, increasing their marketability.
