VEDABRITE diamond export business is completed at the Shanghai Diamond Exchange.In order to facilitate national and global partners, the company has set up a cargo inspection center in Shanghai, and provides professional full customs declaration and logistics support. The Shanghai Diamond Exchange is a national-level diamond market established on October 27, 2000 with the approval

Building on a validated market outlook and proven technical roadmap, Vibede plans to construct a new Phase II facility of 25,000 sqm of advanced manufacturing space, deploying 1,000 MPCVD units dedicated to the scaled production of large single-crystal diamond materials. This strategic capacity expansion is designed to provide reliable, cutting-edge material solutions to partners across

In HPHT synthesis, when it comes to large-scale mass production, system stability always takes precedence over pushing extreme parameters. Cubic presses are extraordinarily sensitive; even minor fluctuations in ambient workshop temperature can translate into uncontrollable pressure variations within the synthesis cavity. Traditional facilities often rely on massive forced-cooling systems (high-capacity central air conditioning) to combat

By optimizing the catalyst formula and stabilizing the growth pressure, we have overcome the challenge of internal consistency in diamonds, producing “high-density, low-stress” rough diamonds. These rough diamonds are resistant to cracking during cutting and polishing, bringing a high and predictable yield rate to downstream factories.

HPHT (High Pressure High Temperature) synthesis cycles last for several hundred hours. Any millisecond-level voltage drop or power grid fluctuation can instantly disturb the thermal-pressure field, causing growth lines, internal stress, or inclusions. The ultimate consequence at the cutting stage is stone breakage and low yield—an industry-wide pain point that is difficult to solve. At

In HPHT synthetic diamond production, humidity is not the most critical technical variable — but it is a stability factor that has long been underestimated. Synthetic pyrophyllite assembly components are moderately hygroscopic. When moisture content is elevated, water vaporizes and expands under high-temperature, high-pressure conditions, potentially causing: In southern regions, where ambient humidity remains high
