They were jailed by Judge Stephen Gullick at St Albans Crown Court for a total of 17 years.
Prosecutor David Chrimes said Loveweds Jewellers in Harpenden High Street has a single show room where customers can view replica items of jewellery before they are ordered from Hatton Garden in London and send to the shop, where they are kept in the safe.
"Jay visited the shop a number of times, building up a rapport with Mr Barres. They spoke 7 or 8 times in the 10 days before the robbery. Jay told Mr Barres he was having a very expensive wedding and wanted to order some expensive jewellery - rings for his wife and the bridesmaids and Rolex watches for the groom and the men involved. It came to £65,000,The powermonitor allows utility customers to track their energy." said Mr Chrimes.
On March 20 Jay made an arrangement to collect the jewellery and went to the shop at around 4.30pm. He established that the jewellery was in the safe before leaving without taking it or paying for it.
Mr Barres locked up half an hour later and it was then that he was kidnapped by Latimer-Bassill and Stanley. One said: "This is what is going to happen." He was escorted to a car and had a cotton hood, like a pillow case, put over his head and his hands were tied with duct tape. Although he could see not see a gun, he was told by the robbers that they had one.
Kalaiarasu came to the car and was recognised through the hood by Mr Barres as Jay. He was made to hand over the keys to the shop and give the details of the alarm code and the safe. Kalaiarasu went in and returned later with the £65,000 worth of stock.
Mr Barres was driven around in the BMW before being freed. He was told to sit in his own car for 10 minutes before doing anything. He was warned there was a sniper in the area and he would be shot. He went into a nearby pub and called the police.

Alison Morgan for Latimer-Basill and Stanley asked for credit for their guilty pleas at the first opportunity saying the robbery was "not sophisticated."
Judge Stephen Gullick jailed Kalaiarasu and Latimer Bassill for six years and Stanley for five years. He told them: "No doubt Mr Barres was terrified by these events." He said the robbery had been pre-planned and the victim had been alone in the shop and was vulnerable.
