Geologically speaking, Ratanakiri Province is part of the Indochinese Craton formation, which extends across Southeast Asia and covers parts of Cambodia, Thailand, Myanmar and Vietnam; Due to similar geological conditions in these countries, zircon deposits have been found in several locations outside of Cambodia, producing brown gemstones suitable for heat treatment to induce a blue color. Recommended Article: A new dimension in every facet - The blue zircon state has been successfully produced from reddish stone found in Bang Kacha and Tok Prom areas of Chanthaburi Province, Thailand, Bo Phloi area of Kanchanaburi Province, Thailand, and mined redstone in the central plateau of Vietnam and Shan State in Myanmar.
In 2021, a new brown zircon deposit was discovered near Maripa in the Chikwawa district of southern Malawi, some of the gemstones from this discovery were blue in color after heat treatment, although little has been produced to date gem material from this deposit, some green metamorphic zircon gemstones from Sri Lanka may also turn light blue after heat treatment. Although blue zircons are found in many locations, the Ratanakiri province of Cambodia remains the largest single source of this variety of zircon.

Oxygen-free conditions are created within the crucible. In some cases, brown gemstones can become colorless when heated. Interestingly, treated zircon gemstones do not appear blue immediately after reaching the ideal treatment temperature, heated gemstones will initially take on a white or silver hue; only freshly treated zircon that has been properly chemically treated after being allowed to cool. lovely blue tone. Another interesting aspect of these treated gemstones is that some gemstones have been reported to temporarily change color in response to exposure to light, a phenomenon known as "senescence"; It turns brown for a while and then returns to its original blue hue. Without heat treatment, the use of blue zircon in gemstone jewelry would be greatly reduced, as blue is the rarest color that this mineral produces naturally without human intervention, followed by green and then red. There have been anecdotal reports from Vietnam, Cambodia, Myanmar and Sri Lanka.
