New York, NY- Manhattan District Attorney Alvin L. Bragg Jr. today announced the guilty plea of MANASHE SEZANAYEV, 41, for defrauding two diamond merchants by covertly swapping their diamonds for lab grown stones – worth substantially less than natural stones – that were cut to resemble the diamonds that the merchants had been offering for sale.
SEZANAYEV pleaded guilty in a New York State Supreme Court to Grand Larceny in the Second Degree. Under the terms of his plea, he is expected to be sentenced to 5 years of probation and make restitution in the amount of $200,000, which has already been paid. The $200,000 diamond was also returned to the victim. SEZANAYEV pleaded guilty on February 27, 2025.
“Manashe Sezanayev is facing accountability for stealing diamonds from merchants and replacing them with fake stones,” said District Attorney Bragg. “We will continue to prosecute those who take advantage of consumers and conduct business deals in a dishonest manner.”
According to court documents and statements made on the record, and as admitted in the defendant’s guilty plea, in early 2024, SEZANAYEV operated his company, Rachel’s Diamonds, in the Diamond District in Manhattan.
On February 5, 2024, a diamond merchant visited SEZANAYEV at his office with two diamonds that SEZANAYEV claimed to be interested in buying, valued at approximately $185,000 and $75,000. SEZANAYEV inspected the two stones and turned his back to the merchant to weigh them on his scale. He swapped the diamonds for lab grown stones that had been recut to imitate the natural stones and inscribed with forged Gemological Institute of America (“GIA”) laser inscriptions.
On March 27, 2024, SEZANAYEV told a second diamond merchant that he had a customer interested in buying that merchant’s diamond, valued at approximately $200,000. That same day, SEZANAYEV purchased a lab grown stone that was later recut to resemble that natural diamond and inscribed with a forged GIA laser inscription to mimic that natural diamond.
On April 2, 2024, the second merchant met with SEZANAYEV and the purported customer, and SEZANAYEV examined the merchant’s diamond. That merchant later learned that the stone SEZANAYEV returned to him was a lab grown diamond that was cut to resemble his stone.
