Forever shines bright with the best lab-grown diamond engagement rings in Singapore!

Quality: The diamonds’ colour, clarity, cut, and carat specifications were assessed through detailed grading reports or articles. Sample inspections from portfolios and customer reviews were considered as well.

Reputable Certifications: We selected stores certified by internationally recognised labs like GIA (Gemological Institute of America) and IGI (International Gemological Institute). Naturally, those with more accreditations gained higher points.

Customisability: Our team reviewed website service offerings, made calls, and conducted in-store visits to identify if a store accepts customised jobs. The more personalised their service, the higher we scored them.

Customer Service: This criterion was scored based on responsiveness, helpfulness, and politeness tests, done through in-store visits and phone/email enquiries. After-sale support and transparency also shaped our decisions.

Ethical Sourcing: Stores that do ethical sourcing, like CVD or HPHT, were given preference.

When my cousin ‘casually’ dropped that he was ring shopping for his girlfriend, I caught the drift fast-fast. That was definitely code for ‘I need your help.’

He was pickier than most grooms-to-be because his girl is eco-conscious. Mined gems won’t cut it.

That’s when I suggested getting a lab-grown diamond engagement ring, a cheaper and more earth-friendly alternative. He agreed, and the rest was sweet history.

So, if you, too, want cruelty-free gems, you’re in luck. Below are Singapore’s best stores for sparkling promises, minus the heavy guilt and heavier price tags.

My cousin eventually popped the question with a ring from Les Precieux, and he beamed right after. She said yes and is still swooning over the piece.

Truthfully, I wasn’t shocked. Most of the store’s diamonds, like the one he bought, carry a GIA-AGS Ideal 0 and GCAL 8x rating. In plain English, that translates to the highest mark for light performance and precision cutting.

We learned that from the patient and well-informed consultants like Janice and Ryan. Both listened to our ideas, explained stuff, and shaped a detailed sparkler for our budget.

Selection-wise, we were impressed as well. The store had over 200 ready designs to try on, one of the biggest selections in Singapore. 

Their custom rings, however, often take 4–6 weeks to complete. Gem shoppers also crowd the store even on Saturdays and Sundays; best to ring and set an appointment.

Pros

  • GIA-AGS Ideal 0 and GCAL 8x rating
  • Reasonable pricing
  • Free resizing
  • Over 200 rings to try on
  • Adjusts to your budget
  • Operating since 2010

Cons

  • Bespoke rings take time to complete
  • Store gets packed

Quality Exceeded Our Expectations

‘Janice was amazing in coordinating the customisation of our proposal and wedding rings. She was attentive, professional, and guided us through every step with great care. The craftsmanship and quality exceeded our expectations, and her warm service made the experience truly special. Highly recommend her to anyone looking for a meaningful and personalised ring design!’

Made the Whole Experience Unforgettable

‘I’m happy with my engagement ring experience with Janice and I truly appreciate how Janice made the entire process so special. Though I haven’t seen the ring yet (my bf has), he’s sure I’ll love it! Janice took the time to listen carefully to my preferences and specific shades of lilac, offering a variety of suggestions and styles with so much patience. I had trouble deciding and kept changing the ring design but she was dedicated to making sure the ring was something I would adore and kept reassuring me that the particular design I chose would be something I love.

I also purchased an engagement ring for my bf and she worked hard to keep the ring within my budget, which I really appreciate. Her attention to detail and care throughout the process made the whole experience unforgettable. I can’t wait to finally see my ring in person! :)’

BA.SG gave us a shiok jewellery shopping experience. Staff like Lucas and Amanda particularly made it easy with their breakdown of each in-store diamond’s 4Cs.

The pricing also didn’t push us away. Brick-and-mortar rates didn’t differ that much from the price tags online, and they’re all fair for Singapore’s standard.

That actually surprised us. We were preparing for premium pricing since their lab-grown diamonds are GIA and IGI-certified.

They also showed us a palette of fancy colours, like green, yellow, pink, and blue. Cut options were just as plentiful, with round and pear shapes among our favourites.

Unfortunately, doors shut on Sundays. Most stores here operate daily.

We’d also appreciate it if more ready-to-wear options were made available, like the first entry.

On the upside, special services are provided. Ring rentals and engraving stood out to us, especially since the latter can be done in 20-plus fonts, including special characters.

Pros

  • Reasonable prices
  • Offers ring engraving and rentals
  • Engraves special characters
  • Diverse colour and cut options
  • Offers same-day delivery

Cons

  • Sunday closure
  • Fewer ready-to-wear options

Well Coordinated

‘The initial arrangements were scheduled by Jimmy & Chris. Our appointment was well coordinated as it should be, with no hiccups. Ended up going to them by sheer luck after months of browsing the web and comparing prices/designs. Decided to choose them for their lab-grown diamond selection, and it was Indeed a good choice. Prices were surprisingly competitive and they had the specs and design that I was looking for. Amanda was the one who guided me through the process of purchasing/selecting the ring and also on things to take note of. The team was accommodating throughout the whole time. Came back a 2nd time 3 months later to collect the ring, as arranged and was not disappointed (Pics below). Will look to go back for the wedding bands. Hoping for a smooth proposal! Thanks again Jimmy, Chris, Amanda & team! Truly a hidden gem. *Pun intended.’

Top-Notch Service and Fun Experience

‘I was recommended by a friend who also purchased his engagement ring here. Checked out a few other spots with lab-grown diamonds nearby, but hands down, the service here was top-notch!

Chris not only gave us a crash course on the 4Cs but also prepped the diamonds for us to check out, and he even threw in a diamond test (phew, we passed!).

Amanda was a lifesaver when it came to our diamond concerns. She answered all our questions like a total pro, and her suggestions for alternative options were a game-changer.

Big shoutout to Lucas, too – he helped us track down the perfect diamond, both in-store and online.

The whole team made the whole experience not just informative but a lot of fun for both me and my boyfriend. Huge thanks to Amanda, Chris and Lucas for making it all so awesome!

Counting down the days until I can swing by and pick up my ring!’

Though we didn’t bag a ring from The Better Diamond, our interviewees and teammates who did had good things to say, especially about their custom work.

For starters, this retailer’s staff is communicative. Technical bits are simplified at the start, and they’ll call you first for updates or design input.

Each client also gets one dedicated consultant; you won’t get shuffled from one staff member to another. That consultant will then ask about your budget and wishlist before whipping up possible designs.

Another positive is their virtual inspection tool. Clients get to view their rings in 360° and zoom up to 40x. If you see something you don’t like, you can raise the concern immediately instead of waiting a day or two.

Now, the flip side: their process is slower than most, usually taking about 8–10 weeks. Plus, you can only browse online since a physical store isn’t available.

Pros

  • Clients get a dedicated consultant
  • Detailed online inspection tool
  • Easy to reach
  • Available 24/7
  • Offers other services like jewellery repair

Cons

  • No physical store
  • The process takes about 8–10 weeks

Really Patient

‘Marcus is excellent. The Better Diamond helped me create the ring I envisioned proposing with. They are really patient every step of the way and provided timely updates on the ring design & construction. When I first saw the ring in person, I was truly amazed at the quality and beauty of it. Thank you TBD, for the amazing service!’

The Process Was Stress-Free

‘I had a good experience purchasing a pair of diamond earrings some time ago, the process was stress free and pleasant. Recently I needed some repair works due to my own damage, I had the good fortune to be assisted by Marcus. The experience has been exceptional, and I commend his efforts in delivering service excellence. Thanks again!’

We gave Novita high marks for convenience.

No other entry has an online customiser as user-friendly as theirs. Even the gem rookies we spoke to didn’t have much trouble using it for personalisation and budgeting purposes.

Basics like clarity and shape are all there, and if you know a bit about gemology, advanced options like preferred symmetry and polish level can be played with.

If you’d rather not fiddle with the settings yourself, the Singapore showroom is good news. The collection of lab-grown diamonds there is massive; we perused about 825!

Angeline, our consultant, was also informative without hard-selling. Most first-time shoppers and buyers echo that.

Moreover, the store runs promotions frequently.

Our main gripe? The showroom can get jammed. Not every piece qualifies for the same-day delivery, either.

On the upside, clients can avail of a one-time, free engagement resizing service during the first 12 months of their purchase date.

Pros

  • Detailed and user-friendly online customiser
  • Showroom has over 825 options
  • Free one-time resizing service
  • Lifetime warranty

Cons

  • Showroom can get jammed
  • Same-day delivery doesn’t apply to every purchase

Genuine Care

‘I had a wonderful experience with Novita when choosing my engagement ring! Angeline was incredibly helpful, patient, and knowledgeable, guiding me through the entire process with genuine care. She took the time to understand what I was looking for and provided great recommendations without any pressure. The quality and craftsmanship of the ring exceeded my expectations, and I couldn’t be happier with my purchase. If you’re looking for a beautiful, well-crafted ring with excellent customer service, I highly recommend Novita—especially Angeline!’

Pleasant, Patient, Calm

‘I needed to take a look at the earrings that I was buying online as a gift so I booked an appointment off their website easily and went to their office on the same day. I thought I would be visiting a warehouse or something but no, I was delighted to be cordially greeted by a very experienced consultant with over 30 years in the jewellery business. She was very pleasant, patient, calm and showcased to me a selection of other jewellery which I will definitely be considering for the next purchase. I won’t be returning to the common retail brands anymore – I’ve found a gem here 😄 It’s really a good and refreshing experience. On top of that, the craftsmanship and packaging is awesome compared to what I’ve seen at shopping malls. I have no qualms buying lab grown diamonds knowing about the environmental impact and ethical concerns centred around it. I’m very satisfied with my purchase.’

Beyond their signature artisan rings, Authica’s crew won over many clients we chatted with. First-time shoppers especially loved that their vision and budget were respected by the accommodating staff.

The store’s face-to-face consultations are also refreshing; meetings are done in a comfy lounge setup instead of a glitzy room. When we called to ask why, Authica explained that it’s to encourage authentic convos instead of ‘too salesly’ talks.

If you’re not the ‘in-person’ type, though, you can request an online appointment.

Now let’s talk diamonds. Their GIA and IGI-certified UltiCut range impressed us since it’s made up of just 1% of their finest lab-grown gems.

Authica’s gems also mimic the classic 58-facet brilliance of mined ones, but they’re about 60% cheaper and more eco-friendly.

However, there are snags. Being closed on Sundays is one.

In addition, changing your mind post-purchase would mean paying a 400 SGD recycling fee.

Pros

  • Low-pressure in-person consultations
  • Premium UltiCut range
  • Free one-time resizing
  • Does online appointments

Cons

  • Sunday closure
  • 400 SGD recycling fee (for returns only)

Professional and Reliable

‘There are some place in life where you will find certainty. Authica J provided us with the sense of security, with how professional and reliable they are to deliver the best diamond jewellery. Paired with aesthetic ring designs, their ring became so awe-inspiring. Despite the tight timeline we demanded them to complete the ring within, not only did they complete it well within the timeline, they provided explanations to every detail necessary to the preservation of the diamonds.

When we received the ring, we were informed that the ring had a scratch at the prong which we couldn’t even see. After collecting the ring for the proposal, we were advised to return it to get the scratch removed. My fiancée did not even want to return it because of how pretty it was.

It’s was a very wholesome experience, because they didn’t make something so personal, transactional. If you like diamonds, you like aesthetic designs, you like a wholesome chat. This is your place. And yes it was so good, I wrote this long a review.’

Very Pleased with How the Ring Turned Out

‘A long overdue post — we had the most pleasant experience designing our engagement ring and wedding rings with Authica J!

My husband first worked with Sharon on the engagement ring – she was extremely helpful in guiding him throughout the process and immediately understood the vision and requirements for the ring. Sharon also offered great suggestions and advice. The ring design was a total surprise to me but it was just perfect! My husband and I were very pleased with how the ring turned out and returned to customise our wedding rings with them!

Sharon proposed a design for my wedding ring which maintains a similar motif to the engagement ring and interconnects beautifully with it, while my husband’s ring has a rose gold design in the inner layer while maintaining its “ruggedness”. We loved every bit of the process and looked forward to each consultation/visit with Authica J — the experience was so unique and meaningful to our wedding planning journey, just like the symbolic meanings we’ve given to our ring designs!

10/10 highly recommend Team Authica J for the personalised service with a touch, the beautiful designs and amazing after-care service!’
