Custom-Made Diamond Jewelry, Designed Around You

Some pieces are chosen. Others are created from a conversation, shaped by what matters to the person wearing them, and built to last far beyond the occasion they were made for.

Custom-made jewelry at LeCaine Gems begins with a brief and ends with something that cannot be found in any display case. Engagement rings, wedding bands, Si Dian Jin sets, anniversary pieces, pendants, earrings, and bracelets — each one handcrafted in 18K gold or platinum, set with independently certified diamonds or gemstones, and made to a specification that is entirely yours.

Why Choose Bespoke

The case for bespoke diamond jewelry is not simply about having something unique. It is about the quality of the decision itself.

When a piece is designed around your brief, every element is chosen deliberately: the metal, stone grade, setting style, and the proportions. There is no compromise to an existing design, and no settling for a stone that is close to what you had in mind.

A few things that distinguish a bespoke commission from buying off the shelf:

  • The stone is selected to your specification, not assigned to a setting.
  • The setting is designed around the stone, not the other way around.
  • Budget is applied where it matters most to you, whether that is carat weight, cut quality, metal, or design complexity.
  • The piece reflects the person it is made for, rather than a trend or a catalog decision.

For significant occasions such as engagements, weddings, anniversaries, or gifts that are meant to last a lifetime, custom-made diamond jewelry tends to carry a different kind of weight than something purchased ready-made.

THE PROCESS, STEP BY STEP

A one-to-one consultation, in person at the Millenia Walk boutique or virtually. You may come with reference images, a specific stone in mind, a rough sketch, or simply a feeling. The conversation covers metal preference, gemstone, setting style, and timeline.

A 50% deposit is required to begin, allowing the artisans to source the specific materials for your piece and start work on the agreed timeline.

A detailed sketch or digital rendering is produced before any metal is cast or stone is set. This is an opportunity to review and refine before production begins.

REASONS TO CHOOSE LECAINE GEMS

  • Certified gemstones as standard. Every diamond and significant gemstone in a bespoke commission carries independent certification from GIA or IGI. The grading report is included with the finished piece.
  • No design fees. The consultation, sketch, and rendering are part of the commissioning process, with no charges for the design stage.
  • Transparent pricing and timelines. Costs, lead times, and material options are communicated clearly from the first conversation.
  • In-person and virtual consultations. The process works for clients in Singapore and internationally, with virtual appointments following the same brief and rendering process as in-person ones.
  • Heirloom and client-provided stone commissions accepted. Existing stones and pieces brought in for redesign are assessed during the consultation, with honest guidance on what is practical.
  • Open daily at Millenia Walk. The showroom is open seven days a week, 11am to 8:15pm, including public holidays.

FREQUENTLY ASKED QUESTIONS

1. What types of jewelry can be custom-made at LeCaine Gems?

The bespoke service covers the full range of fine jewelry. The most common commissions are engagement rings and bridal sets, but the service extends to wedding bands, Si Dian Jin sets, anniversary pieces, pendants, necklaces, earrings, and bracelets. Heirloom pieces brought in for redesign are also accepted.

 If there is a specific piece in mind that does not fit a standard category, the consultation is the right place to discuss whether it is achievable.

2. How much does custom-made diamond jewelry cost in Singapore?

Commissions typically begin from SGD $2,000, with the final cost depending on the choice of metal, stone specification, and design complexity. A plain solitaire in 18K gold with a lab-grown diamond sits at the lower end of that range. A more intricate design set with a natural diamond in platinum will sit considerably higher.

Because the budget goes directly to materials and craft, there is no designer brand margin built into the price.

3. How long does a bespoke diamond jewelry commission take?

Production takes 4 to 8 weeks from the point of design approval. Including the consultation and rendering stage, starting at least 10 weeks before your intended date is the most comfortable approach for anyone working toward a specific occasion.

4. Can I use my own diamond or gemstone in a bespoke commission?

Yes. Client-provided stones are accepted, and the consultation is the right point to bring them in for assessment. The stone’s dimensions, cut, and condition will all influence which setting options are practical, and guidance on what works best is part of that conversation.

5. What if I do not know exactly what I want?

Most clients arrive without a fully formed brief, and the consultation is designed for this. The conversation is used to explore preferences, narrow down options, and arrive at a direction that feels right. The rendering stage then provides a concrete visual to react to before any commitment is made to production.

6. Is bespoke diamond jewelry a good investment?

As a financial asset, jewelry is not the most reliable store of value. As a personal investment in quality and longevity, a well-made bespoke piece tends to hold its significance in ways that a ready-made design often does not. It is made to your brief, your proportions, and your budget, and that specificity translates into something that is genuinely worn and valued over time.

7. What metals are available for a bespoke commission?

18K yellow, white, and rose gold, as well as platinum, are all available. Platinum is the most durable and suits pieces with intricate settings or stones that benefit from secure holding. 18K white gold achieves a similar look at a lower price point. Yellow and rose gold have their own distinct character and suit a wider range of skin tones. The right choice is covered during the consultation.

8. Can a bespoke commission be done remotely?

Yes. Virtual consultations follow the same process as in-person appointments. The brief is developed over video call, references are shared digitally, and the sketch or rendering is reviewed and approved remotely before production starts. The finished piece is then delivered.

9. What happens if I want to make changes after seeing the rendering?

The rendering stage exists specifically to allow for adjustments. Changes to proportions, setting style, or design details are made at this point, before production begins. Once production has started, changes become significantly more difficult and may affect both the timeline and the cost, which is why the rendering review is taken seriously before sign-off.

10. How are the diamonds and gemstones in a bespoke piece certified?

All diamonds and significant gemstones in bespoke commissions at LeCaine Gems carry independent certification from GIA or IGI. The grading report accompanies the finished piece and provides a permanent record of the stone’s specifications, including cut, color, clarity, and carat weight.
