GIOIA Fine Jewellery is a private bespoke jewellery boutique at International Plaza, Singapore, established in 2016. We specialise in customised engagement rings and fine jewellery set with rare coloured gemstones: unheated pigeon blood rubies and royal blue sapphires, teal sapphires, Paraiba tourmalines and Muzo emeralds. Every gemstone is chosen and checked by Clarence Yee, our co-founder and gemstone specialist. Cheryl Woon, an HRD Antwerp certified diamond grader and NAFA jewellery design graduate who completed GIA's Colored Stone Essentials course, leads the design of every commission from first sketch to finished piece. Centre stones above about SGD 1,000 come with an independent laboratory report, mainly from GRS or GIA. Each piece is made from scratch as an individual commission. Rated 5.0 stars across more than 400 Google reviews, and recognised by Singapore Tatler as one of Singapore's top jewellers. Featured in Her World Brides, Tatler Singapore and Honeycombers.
