You don’t need to be an expert
Proposing is the big step.
Choosing the ring should be the easy part.
You don't need to know diamonds
We'll explain cut, colour, clarity and carat in plain language and show you options inside your budget.
We'll get the size right, discreetly
Surprising them? We have quiet ways to find their ring size before you ask.
You approve it before it's made
You see it before it's made, life-size, so there's no guessing.
The stone
The stone is the heart of the ring. Let's get it right.
Lab-grown or natural? Both are real diamonds, graded to the same standards. We offer both and explain the trade-offs without pushing you either way. Lab-grown typically costs significantly less for the same size and quality.
The 4Cs, in plain English. Cut, colour, clarity and carat. We’ll show you what actually changes how a stone looks, and what doesn’t, so your budget goes where it counts.
Your own stone, diamond or gemstone. Reset a family diamond, or choose a coloured gemstone like a sapphire, at no extra design charge.

“Had an amazing experience purchasing an engagement ring. Everyone in the store was super friendly and knowledgable. The work they did for my custom ring was perfect, very detailed and no defects. My ring was even ready before the deadline I gave them, and I gave very short notice.”

Planning a proposal
Proposing soon?
We've done this hundreds of times.
Finding their size, secretly
Borrow a ring they already wear, or tell us what you can and we'll work it out. If it's slightly off, the first resize is on us.
On a deadline or travelling
Standard crafting is 2–4 weeks; a rush option runs 5–10 days. Many clients consult on one trip and collect on a return, or we ship to you.
Keeping it a surprise
Discreet communication, plain packaging, and shipping to your hotel or home. They won't know until you want them to.
Prefer to propose first and perfect the details together afterward? That works too. The complimentary resize and design tweaks make it easy.

No pressure, no surprises, except the one you’re planning. Here’s exactly what to expect.

Crafting
Made by hand in our studio. Standard 2–4 weeks; rush 5–10 days.
The moment
Collect in-store or ship discreetly with full insurance. Complimentary resize included.
Questions & answers
Everything a first-time proposer wants to know
Quietly borrow a ring they already wear on that finger and bring it (or a tracing) to us. If that’s not possible, tell us what you can and we’ll help you estimate. Your first resize is complimentary, so a small miss is easily fixed.
We offer both and walk through the trade-offs with you. Both are real diamonds graded to the same standards; lab-grown typically costs less for the same size and quality, while natural carries traditional rarity.
Allow 2–4 weeks for crafting after you approve the design, plus a little time for the consultation and sketch. On a tight timeline? A rush option of 5–10 days is often available. Just tell us your date.
Yes. Many clients propose with the finished ring and bring their partner in afterward to fine-tune the fit or details. The complimentary resize and our flexibility make this stress-free.
Yes. Discreet communication, plain packaging, and insured shipping to your hotel or home, so they won’t know until you want them to.
Our gold settings start from 29,000 THB and we’ll build around a stone that fits your budget, guiding you on where the money makes a visible difference and where it doesn’t. A comparable custom ring abroad often costs several times more.
Yes, and we love doing it. We’ll assess your stone at the consultation and design a new ring around it, at no extra design charge.
Yes. Our diamonds come with certificates, so you know exactly what you’re giving.
No. At the same karat they’re priced very similarly here. Many clients are surprised by this. Choose the colour you love; it’s an aesthetic decision, not a budget one.
Yes. We ship worldwide with full insurance and tracking, and you can order entirely remotely via Line, WhatsApp or email. We’ve sent rings to clients in the US, UK, Australia, Europe and beyond.
