OUR STORY

Extra Spark is a university research background-based institute. In a clean lab based in the technology center of Shenzhen, South of China, gem quality diamonds are grown with ultra care by our scientists. It is far from easy to create diamonds above the ground – most of our early experiments failed.

EXTRA SPARK

Extra Spark's diamonds are created in either plasma or extreme pressure and heat environment, both mimic the method of natural diamond formation.

Using advanced devices, Extra Spark creates lab-grown diamonds of exceptional quality and brilliance that rival natural diamonds. They prioritize transparency, sharing every step of the diamond's journey from the lab to the polished gem, while supporting a more ethical and environmentally responsible diamond industry.
