Authorities from the Consumer Protection Police Division (CPPD) confirmed that the investigation began after a group of victims filed formal complaints in late December 2025. Many customers said they trusted the seller due to her polished online image and recognition as a successful entrepreneur. As the probe deepened, this Bangkok Gems News report reveals how early transactions involving genuine products may have been used to build credibility before questionable items entered the sales stream.
From Genuine Gems to Questionable Stones
According to investigators, the operation appeared convincing at first. Buyers initially received authentic diamonds, reinforcing trust in the seller’s brand. However, later purchases were allegedly replaced with lab-grown stones and lower-grade materials such as 9K gold, despite being marketed as natural diamonds set in 18K gold.
Victims reported that the actual value of the jewellery they received was often more than ten times lower than what had been promised during livestream presentations. The sharp discrepancy between expectation and reality sparked complaints from customers across the country, many of whom only realized the issue after seeking independent verification of their purchases.
According to sources, Nicha had procured the lab-grown diamond jewelry form India Merchants in Silom and Suriwong.
