Best Bespoke Jewellers in Singapore for Custom Rings, Gemstones and Modern Heirlooms

MADLY is for anyone who has ever looked at a classic diamond ring and thought, beautiful, but not quite me. The Singapore bespoke jeweller is best known for rare coloured gemstones, working with the top 0.1% of coloured gems to create pieces that are personal, vivid and completely one of a kind.

Sapphires, spinels, tsavorites, Paraiba tourmalines and other exceptional stones form the starting point here. From there, the design can go almost anywhere you please. A custom engagement ring in an unexpected shade, a birthstone necklace with personality or a cocktail bracelet that turns dinner into an occasion. 

Each MADLY piece is hand-drawn from scratch, with the client sitting alongside a designer to choose stones, shape the design and bring the final jewel to life. The process feels intimate because it is. You are not choosing from a tray. Instead, you are building something around a story, a person, a milestone, or simply a colour that makes your heart do a little flip.

The brand is known for its attention to sourcing. MADLY was the first jeweller in Singapore to become an Accredited Ethical Member of the International Colored Gemstone Association, with full disclosure on gemstone treatments and enhancements. Its gems are responsibly mined, sustainably traded, legally obtained and not sourced through child labour.

As a gift, the result feels thoughtful without tipping into cliché. For yourself, it is a chance to mark a moment in your life with something no one else will own. And really, that is the pull of MADLY: the joy of making jewellery that looks like you, not everyone else.

ART N ASH is a destination for bespoke fine jewellery, from custom engagement rings to timeless diamond tennis bracelets and meaningful milestone pieces. Founded by jewellery entrepreneur Aarti Sonawala, the brand brings together craftsmanship, expertise and personal storytelling to create jewellery designed to be worn, loved and kept for years.

A certified gemologist, diamond grader and designer, Aarti brings years of industry knowledge to every creation. Jewellery craftsmanship also runs deep in her heritage, with her family having been part of the diamond and fine jewellery trade for four generations. That mix of training, instinct and family legacy gives each consultation a reassuring sense of depth.

Every design journey begins with understanding the client’s vision, inspirations and personal story. From there, Aarti translates those ideas into wearable fine jewellery, guiding clients through the details of design, stones, proportions and budget along the way.

Once the design and budget are confirmed, the bespoke creation process takes approximately four to six weeks. What you get is a piece that carries more than fine materials and careful craftsmanship. It holds the thought behind the gift, the meaning of the milestone and the story of the person it was made for.

For engagement rings, anniversary gifts, diamond bracelets or jewellery marking a new chapter, ART N ASH creates pieces that feel personal from the first conversation to the final reveal.

Rachel P Jewels is a private jeweller for life’s bigger moments, from proposals and weddings to anniversaries, family milestones and deeply personal gifts. Best known for dream-come-true engagement and wedding rings, the jewellery house creates one-of-a-kind pieces with meaning in every detail.

The designs often begin with a story. One bespoke sapphire and diamond masterpiece took inspiration from a client’s journey of growth and deep connection with nature. Crafted with timeless elegance, it was made to be cherished today and worn beautifully for years to come.

For another couple, Rachel P Jewels created bespoke pendants inspired by the romance of Beauty and the Beast. Each pendant can be worn on its own, yet the two symbolically become one when brought together.

The house has also created Art Deco-inspired opal earrings set with baguette diamonds and blue sapphires. The result brings vintage glamour and contemporary elegance together, with movement that catches the light beautifully.

Behind these pieces is a close-knit team of craftsmen who have worked with the Rachel P Jewels family for over three decades. They bring each design to life with natural, earth-mined diamonds and gemstones, chosen for their authenticity and lasting beauty. No bespoke design is ever replicated, so every finished piece stays exclusive to its owner.

Have a sentimental piece of jewellery that needs a little care? Rachel P Jewels also restores, repairs and repurposes heirloom jewellery, giving treasured pieces a second life while preserving the memories they hold.

That thoughtful approach continues into each bespoke appointment. Clients work closely with Rachel P Jewels on every detail, from the first idea to the final setting. For a proposal ring, wedding piece, heirloom redesign or special occasion jewel, the finished creation carries the intimacy of a private commission.

The atelier is open by appointment only.

This is a good choice for someone who wants bespoke jewellery that feels less traditional and more design-led, especially for modern heirlooms, engagement rings or occasion jewellery with a sleek point of view.

State Property’s bridal jewellery is also worth a look for couples who want engagement rings and wedding bands that feel romantic without being predictable. The designs have presence, but they are not fussy. They suit those who want fine jewellery that can move easily from a dinner dress to a crisp white shirt.

Caratell is for the jewellery lover who wants craft, colour and imagination in full force. Led by Michael Koh, the Singapore haute joaillerie atelier is known for artistic creations that feel closer to wearable sculpture than standard fine jewellery.

The brand works well for clients who are open to bolder ideas, especially those who want their bespoke piece to feel completely personal. From rare gemstones to detailed settings and whimsical forms, Caratell’s designs often carry a sense of movement and fantasy.

This is not the place to go for something plain. It is where you go when you have a story, a gemstone, or a mood in mind, and want a jeweller who can turn that into something memorable. For milestone birthdays, private commissions, anniversary gifts or showpiece rings, Caratell brings serious artistry to the table.

Choo Yilin has long been associated with jade, heritage and the idea of giving traditional jewellery a more modern life. The brand is especially loved for pieces that take culturally meaningful materials and reimagine them for today’s wearer.

For those with jade sitting in a drawer, or those dreaming of a jade heirloom ring that feels fresh rather than dated, Choo Yilin is a thoughtful name to know. The brand now focuses on private, considered jewellery journeys, including jade heirloom rings, old cut diamond pieces and bangle sourcing.

There is a slower, more intentional feel to the process, which makes sense for jewellery that carries family meaning. This is not about chasing trends. It is about creating a piece that feels rooted, personal and worth passing down.

Beyond Si Dian Jin, the brand also offers engagement rings, wedding jewellery and bespoke options, making it a good stop for couples who want their jewellery to carry a personal story from the proposal through to the wedding day.

The brand also does wedding and engagement jewellery, including custom engagement rings and Si Dian Jin. For everyday pieces, milestone gifts or jewellery that marks a memory in a subtle way, Calla Lily feels personal without being overly sentimental.
