TING DIAMOND: GIA-Certified and Lab Grown Diamonds

[tingdiamond12]

When it comes to buying diamonds, trust and quality matter the most. At TING DIAMOND, we make sure every diamond you buy is genuine, beautiful, and certified by the best in the industry. Whether you’re looking for a natural diamond or a 培育鑽石 (lab grown diamond), we guarantee the highest standards.
Why Choose GIA-Certified Diamonds?
The Gemological Institute of America (GIA) is the world’s most trusted name in diamond grading. Every diamond we sell comes with a GIA certificate, so you know exactly what you’re getting. The GIA created the 4Cs (Cut, Color, Clarity, and Carat Weight), which helps you easily compare and choose the perfect diamond.
Other gem labs also grade diamonds, but their standards are based on GIA’s system. So when you get a GIA-certified diamond, you’re getting the most accurate and reliable grading possible.
The GIA Girdle Number – Your Diamond’s Unique ID
Every GIA-certified diamond has a unique laser-inscribed number on its girdle (the thin edge of the diamond). At TING DIAMOND, we have special tools that let you see this number yourself. This way, you can match the diamond to its certificate and be 100% sure it’s the same stone.
You can also check the GIA website anytime and enter this number to see all the details about your diamond. This transparency gives you peace of mind—no tricks, no confusion, just real diamonds with real certifications.
How We Test Diamonds for Authenticity
We don’t just rely on certificates—we also test every diamond to confirm it’s real.
Diamond Test Pen: This tool checks if a diamond is genuine by measuring how fast it cools down. Diamonds cool faster than other gemstones because of their strong carbon structure.
Diamond & Moissanite Testers: Some gems, like moissanite, look similar to diamonds but aren’t the same. Our testers make sure you’re getting a real diamond, not an imitation.
Want Extra Confirmation? Send Your Diamond to GIA Hong Kong
If you want double verification, you can send your diamond to GIA Hong Kong for a re-check. They will confirm if the diamond matches the certificate. This process takes about 1-2 weeks, and the fee goes directly to GIA.
This service is perfect for buyers who want absolute certainty before making a big purchase.
Expert Help from Professional Gemologists
Buying a diamond can be confusing, but you’re not alone. Our professional gemologists are here to help you at every step. They’ll explain the 4Cs, show you different options, and help you pick the best diamond for your budget.
Whether you want a natural diamond or a lab grown diamond, we’ll guide you to the perfect choice.
What Are Lab Grown Diamonds (培育鑽石)?
Lab grown diamonds (also called lab created diamonds) are real diamonds—just made in a lab instead of the earth. They have the same chemical structure, brilliance, and hardness as natural diamonds. The only difference is how they’re made.
Why Choose a Lab Grown Diamond?
More Affordable: Lab diamonds cost 30-40% less than natural diamonds of the same quality.
Eco-Friendly: No mining means less harm to the environment.
Same Beauty & Quality: They look just like natural diamonds and are graded using the same 4Cs.
At TING DIAMOND, we offer both natural and lab grown diamonds, so you can choose what’s best for you.
A Legacy of Trust Since the 19th Century
GIA was founded in the late 1800s to protect jewelers and buyers from fraud. Today, they continue to set the standard for diamond quality. At TING DIAMOND, we follow these high standards to give you diamonds you can trust.
