Turner must serve a minimum term of 16 years.
With time already served he will be out in 15 years.
Turner, 20, was this morning (NZ time) found guilty of strangling the 17-year-old New Zealander in a jealous rage at his parents' home in Bournemouth.
His father, wealthy jeweller Leigh Turner, 54, and healthcare assistant mother Anita, 51, were also found guilty of covering up the murder.
High Court Judge Linda Dobbs delivered the sentence in Winchester High Court tonight.
The court was earlier told that Turner had boasted to friends "I will kill her. I will go to prison and still be a millionaire when I come out" before he murdered his girlfriend.
Turner, a self-styled 'gangster', met Emily on a double date in December 2010 and they quickly became a couple.
However, he became increasingly suspicious Emily was having affairs during their four-month relationship and began fantasising about killing her.
Prosecutor Timothy Mousley QC told the trial during summing up : "He's remorseless, he's controlling, he's possessive and he's vicious."
Turner practised strangleholds on his friends so tightly they "began to panic and couldn't breathe".
He even told friends he had murdered Emily with a hammer on the night before her murder.
Turner's parents were released on bail for sentencing reports but Judge Dobbs warned them they could also expect jail terms.
