Trusted Source for Lab-Grown Diamonds & Certified Qualit

[tingdiamond12]

When buying diamonds, authenticity is everything. At TING DIAMOND, we guarantee all our diamonds come with GIA, IGI or AGS international certification - so you can shop with complete confidence. Whether you're looking for natural diamonds or popular lab-grown diamonds, we offer the perfect selection for every need and budget.
Why Certification Matters
Every diamond at TING DIAMOND includes:
GIA Certification - The gold standard in diamond grading using the 4Cs (Cut, Color, Clarity, Carat)
IGI/AGS Reports - Alternative certifications with equally rigorous standards
Laser Inscriptions - Each certified diamond has a unique ID number engraved on its girdle
Our store provides precision magnifying equipment so you can personally verify this number matches the certificate. You can also check it anytime on the official GIA/IGI websites.
Lab-Grown Diamonds: Smart & Sustainable Choice
More customers are choosing 實驗室鑽石 (lab-grown diamonds) because:
Identical Quality - Same physical/chemical properties as mined diamonds
Better Value - Typically 30-50% more affordable than natural diamonds
Eco-Friendly - No mining required, smaller environmental footprint
We offer beautiful 人造戒指 (lab-grown diamond rings) in all styles - from solitaires to halo designs.
Our Quality Assurance Process
Diamond Test Pen - Instantly verifies real diamonds vs simulants (moissanite, CZ etc.)
Optional Recertification - You may send your diamond to GIA Hong Kong for verification (takes 1-2 weeks)
Expert Guidance - Our professional gemologists help you understand diamond quality and select the perfect stone
