Where jewellery becomes a language of memory, identity, and enduring beauty.
The Founder
Cecile Private Collection was founded by Cecilia Hermanto, whose journey in jewellery began through formal studies in both design and business. She first pursued Jewellery Design at Nanyang Academy of Fine Arts, Singapore, where she developed her understanding of form, proportion, and the relationship between jewellery and personal expression.
She later continued her studies in International Jewellery Business at Birmingham City University, United Kingdom, which broadened her perspective on the industry — from materials and production to consumer behaviour and the evolving role of jewellery in modern life.
To deepen her expertise further, she also continued her studies at GIA in coloured stones, refining her knowledge in gemstone evaluation with a focus on beauty, optical performance, durability, and long-term value.

Our Philosophy
Established in 2019, Cecile Private Collection was born from Cecilia's love for jewellery and her belief that every piece should be more than beautiful.
For her, jewellery is deeply personal — something that can hold emotion, preserve memories, and reflect the identity of its wearer. This belief became the foundation of the brand, where each design is approached not only as an object of adornment, but as a meaningful piece with its own story to tell.
With a strong design background and a thoughtful understanding of gemstones, Cecilia built the brand around the idea that jewellery should feel personal, intentional, and lasting.

Find your perfect fit
Finding the perfect ring size is essential for comfort and style. Our rings are crafted with precision, and we want to ensure you get the right fit. Follow these simple steps to determine your ring size accurately.
Method 1: Use a Ring You Already Own
Measure the inner diameter of a ring that fits you well. Compare the measurement with our size chart above to find your size. This is the most accurate method if you have a ring that fits perfectly.
Method 2: Measure Your Finger
Wrap a string or strip of paper around the base of your finger. Mark where the ends meet, then measure the length with a ruler. Use the measurement to find your size on the chart above. For the most accurate reading, measure your finger at the end of the day when it's at its largest.
Note: If you're between sizes, we recommend choosing the larger size for comfort. Ring sizes can vary slightly between different finger widths. For custom sizing or additional assistance, please contact our customer service team.
