The likely candidates for the show include the £3.2 million Blue Diamond Flower Ring, which is composed of rare blue diamonds set among eight diamond petals.
Designer David Domoney, who regularly appears on ITV‘s This Morning programme, is known for his innovative designs. Last year, he brought in 20 piranhas for display, and his Ace of Spades garden included a Harley Davidson.

Mr Domoney said of his new garden: ‘This year, it’s high-end and extreme but with a strong horticultural message.
‘We want to show how jewellery has been inspired by plants throughout history, such as use of the thistle in Celtic designs. Many varieties of plants and flowers have been named after jewels and gems.’
The use of such expensive materials has meant that the organisers of the show have had to step up their security.
Bob Sweet, director of the show, commented: ‘There are security issues to address, but we support the novel approach from the designer. David Domoney always seeks to bring an extra thrill to his gardens.
‘We have had valuable sculptures and works of art at Chelsea before, but I think this will be the highest value garden ever to be shown.’
