At Mingren Jewelry, we understand that purchasing fine jewelry is an act of trust. That’s why transparency and authenticity are the cornerstones of our brand.

GIA Certified Gemstones: The Global Standard of Excellence

All our precious gemstones – including diamonds, sapphires, rubies, and emeralds – are meticulously examined, graded, and certified by the Gemological Institute of America (GIA).

  • What is GIA? GIA is the world’s foremost authority in gemology, renowned for its impartial and rigorous standards for gemstone identification and grading. Their 4Cs (Carat, Color, Clarity, Cut) for diamonds, and comprehensive assessments for colored gemstones, are the benchmarks of the industry.
  • Why it Matters: A GIA certificate is your independent proof of quality. It details your gem’s unique characteristics, ensuring you know exactly what you are purchasing.
  • Verify Your GIA Certificate: Every GIA certificate comes with a unique report number. You can easily verify its authenticity and details directly on the GIA website: https://www.gia.edu/

Natural A-Grade Myanmar Jadeite: Certified Purity

Our exquisite jadeite holds a special place in our collection, sourced exclusively from the legendary mines of Myanmar – the undisputed origin of the world’s most coveted jadeite.


NGTC

  • Our Commitment: We guarantee that every jadeite piece you acquire from Mingren Jewelry is natural A-grade (Type A). This means the jadeite is entirely natural, untreated, and has undergone no artificial enhancement processes like bleaching, polymer impregnation, or dyeing. Its beauty and resilience are entirely Earth-given.
  • Why A-Grade Matters: Natural A-grade jadeite retains its original structure, color, and luster over time, making it truly valuable and a worthy heirloom. Treated jadeite (B or C grade) can degrade in appearance and value.
  • Chinese Gemological Certificates: Many of our Myanmar jadeite treasures are accompanied by official certificates from highly reputable Chinese gemological laboratories (e.g., NGTC – National Gemstone Testing Center). These organizations are recognized authorities in jadeite identification and grading within the Asian market.
  • Verify Your Chinese Certificate: Each certificate includes a unique verification code and QR code. You can typically verify its authenticity and details on the issuing laboratory’s official website: https://www.ngtc.com.cn
