Patented Gemstone Cuts
Tulip Cut
Revered for its beauty since ancient times, the tulip took on a sacred status under the Ottomans that endures in the gardens of Istanbul to this day.
In the 18th century, there was such an obsession with the tulip across cultures in both east and west, the period became known as ‘The Tulip Era’ and signified a blossoming of arts, sciences and cultural development. The tulip, always a symbol of love and the loved one, became synonymous with the sultanate and with opulance, power and wealth.
The Istanbul Tulip with its long and elegant shape, depicted in the ornate decoration of Topkapi Palace, has been chosen to create an exclusive cut with an innovative technique for precious stones patented as the ‘Gilan Tulip Cut.’
A tribute to the elegant flower with all its glorious colour that is the symbol of Istanbul.
Theodora Cut
A timeless signature born from the grandeur of an empress
A symbol of courage, elegance, and individuality, the Theodora Cut draws its inspiration from the magnificent jewels worn by the Byzantine Empress Theodora in the iconic mosaic at the Basilica of San Vitale.
Reimagined through Gilan's creative vision, this distinctive four-sided gemstone cut transcends classical forms, revealing a bold and sophisticated silhouette. Its balanced geometry, crisp lines, and architectural structure, which captures and reflects light from multiple angles, give the Theodora Cut more than brilliance—they imbue each gemstone with a distinctive character.
Developed exclusively by Gilan using proprietary techniques and protected by patent, the Theodora Cut is a unique jewellery signature that unites the splendour of the past with the design language of the future.
Like the empress whose name it bears, it is powerful, resolute, and timeless. Distinctive from every angle, the Theodora Cut embodies the confidence, individuality, and refined style of the modern woman.
The Theodora Cut — more than a gemstone cut; it is a new legacy of artistry and craftsmanship, created by Gilan.
