• Real? Yes.
• Certified? Yes (IGI/GIA/NGIC).*
• Best Price? YES in HK.
• The Vibe? Think "The Ordinary" of Diamonds.

Yes, 100%. Without exception. Lab-grown diamonds are pure crystallized carbon, physically, chemically, and optically identical to mined diamonds. They possess the exact same fire, scintillation, and hardness (10 on the Mohs scale). The only difference is their origin—think of it as "ice from a state-of-the-art freezer" versus "ice from a frozen lake."

A standard diamond tester will identify them as diamonds because they are. Even an experienced jeweler cannot tell the difference with the naked eye or a loupe. Differentiation requires highly specialized laboratory equipment used by institutions like IGI or GIA.

Never. Because they are genuine diamonds, they are structurally stable. Unlike simulants like Moissanite or Cubic Zirconia (CZ), which can become cloudy or scratched over time, a Carat Club diamond will retain its brilliance and clarity forever.

Absolutely. Trust is our foundation. Most of our diamonds are verified by leading global institutions such as the International Gemological Institute (IGI) or the Gemological Institute of America (GIA). For the Hong Kong market, we also utilize NGIC for localized, expert verification. Learn more about NGIC and the bracelet certificate standard.

We believe the "Cut" is the most important of the 4Cs. We focus exclusively on Ideal and Excellent proportions to maximize light reflection. We never compromise on cut quality to simply preserve carat weight.

We operate on a "Smart Luxury" model. By bypassing traditional mining cartels, eliminating expensive storefront rents in Central, and removing multi-layered middlemen, we bring direct-to-lab economics to you. You are paying for the diamond and the craftsmanship, not the brand's marketing campaign.

We believe jewelry should be an investment in your identity and daily joy, not a speculative financial asset. While mined diamonds are often marketed as "investments," they rarely retain their full retail value upon resale. By choosing lab-grown, you save significantly upfront, allowing your capital to remain in your actual investment portfolio.

To maintain our disruptive pricing, all sales are final. We do not offer returns or refunds.

Traditional jewelry brands that offer "free returns" must bake that cost into their retail price: often increasing the price of every item by 30% to 60% to cover the logistics and restocking of returned goods. At Carat Club Co., we refuse to make you pay that premium. We believe you shouldn't have to pay for someone else’s indecision. Note: If you are a client who specifically requires a return/refund option and are willing to pay the associated premium, please contact us for a bespoke quote.

Because every piece in the OOO Collection is made-to-order, our standard delivery time is 3 to 4 weeks. We don’t believe in mass-produced inventory sitting in a warehouse. Each diamond is hand-selected and each setting is crafted specifically for you upon purchase, ensuring a level of precision that matches our standards.

This is a core pillar of our honest pricing. By producing only what is ordered, we eliminate the massive costs of carrying unsold stock and expensive inventory insurance. We pass these savings directly to you, allowing us to offer the best prices in Hong Kong.

We recommend a fit that drapes slightly, usually 1cm to 1.5cm larger than your actual wrist size. You can download our Printable A4 Size Guide on the product page to measure accurately at home.

Yes. Every Carat Club order is shipped via a fully insured courier. From the moment it leaves our hands until it reaches your door, your purchase is 100% protected.

To maintain our "Best Price in HK" guarantee, we operate as a 100% online experience. This allows us to cut the overhead costs that traditional jewelers pass on to customers.

You can clean your diamonds with mild dish soap, warm water, and a soft-bristled toothbrush. This removes the natural oils and lotions that can dull the surface sparkle.

While our diamonds are indestructible (Mohs 10), we recommend removing jewelry during heavy workouts or in environments with harsh chemicals (like chlorine pools) to protect the integrity of the metal setting and keep the platinum plating looking pristine.
