Good picks by need

  • For the most established custom experience, JannPaul is a strong first stop.
  • For a lab-grown specialist with lots of social proof, Novita stands out.
  • For a more boutique, appointment-led custom process, look at August Bespoke or Temple & Grace.
  • For central Orchard convenience, Diamond Ateliers and BA.SG are practical choices.

What to ask

When you message or visit, ask these:

  1. Can you design a ring from scratch around my budget?
  2. Do you offer CAD previews before production?
  3. Are your lab-grown diamonds IGI or GIA certified?
  4. Can I choose the setting, metal, and stone shape?
  5. What is the turnaround time for a custom ring?

Quick tip

If you want the smoothest process, shortlist 2–3 stores, compare CAD process, certification, and final price, then book appointments. In Singapore, many of these shops are appointment-based, so it helps to contact them first.

Better starting points

If you want to start with just three:

  • JannPaul
  • Novita
  • Temple & Grace

Would you like me to narrow this down by budget , Orchard-area only , or best value?
