Yes! Lab-grown diamonds are 100% real diamonds—just created in a high-tech environment instead of deep underground. They have the same breathtaking sparkle, the same hardness, and the same brilliance as mined diamonds—because they are diamonds! The only difference? Lab-grown diamonds are ethical, sustainable, and much more affordable than mined ones. That means you can get a bigger, more stunning diamond for your budget, without any of the environmental or ethical concerns of traditional mining. Why pay more for the same thing? With a lab-grown diamond, you get pure beauty, pure value, and pure peace of mind.

Great question! Lab-grown diamonds are created using the same natural processes that form diamonds in the Earth—just faster and in a controlled environment. There are two advanced methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both produce genuine, high-quality diamonds with the same brilliance, hardness, and fire as mined diamonds.

The best part? No destructive mining, no environmental harm, and no ethical concerns. Just stunning, conflict-free diamonds grown with cutting-edge technology. And because we don’t have to dig miles into the Earth to find them, you get the same breathtaking beauty at a much better price.

Why pay more for a mined diamond when you can have an eco-friendly, budget-friendly, and completely authentic diamond grown just for you?

At Hinch&Liu, all diamonds that are above 0.25ct. will be IGI or GIA certified, ensuring that you receive the highest quality and authenticity.

Both IGI (International Gemological Institute) and GIA (Gemological Institute of America) are world-renowned independent gemological labs, and their certifications are among the most trusted in the industry. These certificates provide detailed information about your diamond’s cut, color, clarity, and carat weight—giving you full transparency about the quality of your purchase.

You can easily verify the certification by visiting the official GIA or IGI online report check system, where you can enter the report number to access the full details of your diamond’s certification.

At Hinch&Liu, we believe in providing complete confidence and peace of mind with every purchase.

That’s the beauty of lab-grown diamonds—they’re so identical to mined diamonds that even expert gemologists need specialized equipment to tell them apart!

Lab and mined diamonds have the same physical, chemical, and optical properties, so there’s no visible difference to the naked eye. The only way to distinguish them is through certifications and laser inscriptions—lab-grown diamonds are often marked with a microscopic inscription on the girdle, which confirms their origin.

But here’s the real question: if they look the same, shine the same, and last forever just like mined diamonds—why pay more? With a lab-grown diamond, you get the same breathtaking sparkle, but with better value, ethical sourcing, and a more sustainable choice.

Absolutely not! A high-quality lab-grown diamond will never test as moissanite. Moissanite and diamonds—whether mined or lab-grown—have completely different chemical compositions. While moissanite is made of silicon carbide, lab-grown diamonds are 100% pure carbon, just like mined diamonds.

At Hinch&Liu, we take quality seriously. Every diamond we sell undergoes rigorous testing and certification by our in-house gemologist, ensuring that you receive nothing but the finest, most brilliant diamonds. With our expert quality control, you can trust that your lab-grown diamond is a genuine, high-quality diamond—never moissanite, never anything less.

Absolutely! Lab-grown diamonds will 100% pass a diamond tester—because they are real diamonds!

Diamond testers work by measuring thermal and electrical conductivity, and since lab-grown diamonds have the exact same chemical and physical properties as mined diamonds, they will test as genuine diamonds every single time.

At Hinch&Liu, we ensure the authenticity and quality of every diamond we sell. Our in-house gemologist carefully inspects and certifies each stone, so you can buy with complete confidence. Whether it's tested with a traditional diamond tester or advanced gemological equipment, a Hinch&Liu lab-grown diamond will always prove its authenticity.

Cleaning your lab-grown diamond is super easy—just like cleaning a mined diamond! To keep it sparkling like new, follow these simple steps:

✨ Gentle Soap & Warm Water: Mix a few drops of mild dish soap with warm water. Soak your diamond jewelry for about 15–20 minutes.
✨ Soft Brush: Use a soft toothbrush to gently scrub away any dirt, especially around the setting.
✨ Rinse & Dry: Rinse thoroughly with clean water and dry with a lint-free cloth.

For an extra shine, you can also use a jewelry cleaning solution or take it to a professional jeweler for ultrasonic cleaning.

Great question! The main difference between 14k and 18k gold lies in the amount of pure gold used in the alloy.

✨ 14k Gold is made up of 58.3% pure gold and 41.7% other metals like copper and silver. It’s a bit more durable and affordable, making it perfect for daily wear without compromising on beauty.

✨ 18k Gold contains 75% pure gold and 25% other metals. This gives it a richer, deeper color and a more luxurious feel. It’s a great option if you want a higher gold content, though it can be a bit softer than 14k.

Both are stunning choices, but 18k gold is often preferred for its premium look and higher gold content, while 14k gold offers a balance of strength, beauty, and value.

At Hinch&Liu, we offer both options in our jewelry, so you can choose the one that fits your style and lifestyle best.
