Stable, Reliable and
Direct Supply

Our factories in Asia are now able to produce 3000 to 4000 lab-grown diamonds per month. All the inventories on our website are real diamonds in stock and will be updated weekly to help our clients with the latest information.

As a factory-based supplier, we have the capability to offer competitive prices in the lab-grown diamond market. Without the middlemen and platforms, we believe that our clients could take advantage of this and rapidly grow in the industry.

Thanks to our own factories, we could directly supply diamonds at stable and competitive prices. There are no more misleading Ad Prices, fluctuations or discrepancies in diamond prices. Even if the diamond you choose is sold, we could guarantee to match you with a similar diamond or produce the same diamond for you in the next batch (1-2 weeks).
