Frequently Asked Questions
Why is your price so low—what’s the catch?

No catch. Three simple reasons:

  • We pre-book a small batch for this promotion of top-grade diamonds in popular sizes, so suppliers give us better rates.

  • We make each ring after you order, so we don’t pay for big stock or pricey shop rental space—and you don’t pay for that either.

  • Our price is straight, based only on the diamond’s grade and the current gold & platinum price.

Proof you can check: Every diamond has an independent hardcopy lab report from International Gemological Institute (IGI) with a laser number you can verify online.

Note: Quantities are limited for those sizes. If it suits you, you can proceed with confidence.

How do I know this is genuine—and safe to proceed?

1) Check the diamond’s ID
Every diamond has an independent lab report (GIA/IGI) and a laser number on the stone. We list this number on your sales order/invoice.

  • We’ll show you the laser number on the diamond (in person or video) and the hard-copy report.

  • You enter that number on the lab’s website to confirm it matches.

2) Check the business
We’re a registered company with a sales office (by appointment).

  • Read our *5 Star Google reviews (SG & MY) since 2012.

  • Visit us before paying if you prefer.

3) Check the payment
Pay only to our company account (PayNow / Card / Bank Transfer).

  • Your invoice is in our company name with full details.

  • We never ask for payment to a personal account.

4) Check your protection
We offer a 14-day money-back option on eligible items (simple T&Cs) and after-sales care for fit and finishing.

Bottom line: You can verify the diamond, the company, the payment, and your protection before you commit. If any step doesn’t check out, don’t buy. If it does, proceed with confidence.

Can I change the ring size or get after-sales service after I buy?

Yes. This seasonal offer includes TJ Basic Care:

  • 1 free resize

  • Polishing or plating

  • Valid for 24 months from the invoice date

Upgrade option: TJ Lifetime Care (add-on)

  • Same after-sales support, with up to 3 resizes over the lifetime of the piece

Important

  • ⚠️ A surcharge applies if the size change is 2 US sizes or more

  • Some materials can’t be resized (we’ll advise before any work)

How to use it

  • WhatsApp us with your order number to book a care appointment

What happens after I place my order (online or in person)?

We keep it simple and transparent.

  1. WhatsApp welcome
    Our Customer Care team messages you to confirm details and answer any questions.

  2. Order confirmation & invoice
    You’ll receive your order summary and e-invoice online.

  3. Build tracking
    We send you a tracking link with milestones (cast → set → polish → ready) and your estimated timeframe.

  4. Collection or delivery
    When your ring is ready, we’ll WhatsApp you to book collection at our sales office or arrange insured delivery.

  5. After-sales, same channel
    Keep the same WhatsApp chat for fit adjustments, finishing, or any care needs after you receive the ring.

Notes: We reply during weekday working hours. If you have a special date, tell us early—we’ll confirm what’s realistic before you pay

How long will it take—can I get it by my date?

4–6 weeks for most rings. (Festive seasons may add time— we’ll tell you upfront.)

Why it’s worth the wait:
Every piece is made brand new for you, in your exact size. It’s crafted to order—only the craftsman and you handle it—so your ring is truly yours alone, not taken from stock.

Need it sooner?
WhatsApp our Customer Care team and tell us your target date. We’ll do our best to accommodate and confirm what’s realistically possible before you pay.
