The exclusive phone costs between £10,000 and £2.3 million (around $15,300 and $3.5 million) depending on the number of diamonds in the case.

The Diamond Ecstasy collection includes versions of the iPhone 6 covered in 24ct yellow gold, rose gold or platinum, all set with diamonds, of course.

Each model is made to order and priced according to the quantity of diamonds desired. Gift givers can opt to have a personal message laser-engraved on the back of the case.

Goldgenie is not the only company offering a luxury edition of Apple's latest smartphone ahead of Valentine's Day. Accessory designer Alexander Amosu has presented an exclusive pink iPhone 6, which was produced in a limited edition of just 10 devices priced at £1,899 each (around $2,850).
