Marcus Tempus
A classic hoop illuminated in sapphire blue. Céleste takes an everyday jewellery essential and gives it the House of Gemstones treatment.
A graduating curve of sixteen round blue sapphires follows the front of the hoops, each individually claw-set to allow the colour and sparkle of the stones to remain the focus. Their rich blue creates a beautifully crisp contrast against the polished gold, while the neat 12mm profile makes them wonderfully wearable.
Elegant enough for an evening yet effortless enough for every day, Céleste is the sort of sapphire jewellery that never needs an occasion.
