Scientists employ pure natural sapphires as seeds within laboratories, replicating the natural growth environment of sapphires. This process enables sapphires to recrystallise and regrow, resulting in recrystallised sapphires possessing identical mineral composition and gemstone characteristics to natural sapphires.

Within the jewellery industry, these are termed laboratory-grown sapphires. Domestically, they are commonly referred to as ‘cultured sapphires’ or ‘regenerated sapphires’. This designation distinguishes them from conventionally understood artificial gems. They are further differentiated from ordinary blue imitations, as they are all genuine
