Choosing your first engagement ring? You're not alone—many people have similar worries.
Is it possible to find a ring my partner will truly love, even on a budget?
In Japan, the average engagement ring budget is in the ¥400,000 range, and most rings feature a 0.2–0.3 carat diamond (approximately 3.8mm in diameter).
At DIALLURE, we work directly with overseas diamond cutters to eliminate middleman costs. This allows us to offer a 0.5ct (approx. 5mm) ring within the same budget or 1 carat Lab-grown diamond ring —so you can give an engagement ring that truly sparkles on the hand.
Prefer a lab-grown diamond? We’ve got you covered.
Lab-grown diamonds share the same chemical composition and brilliance as natural diamonds, offering a new alternative that’s gaining attention for its environmental benefits and accessible pricing.
While still rare in Japan, DIALLURE offers lab-grown diamonds as an option for every engagement ring design.
Can't find fancy-shaped diamonds?
They’re rarely offered in Japan. At DIALLURE, you can choose from 10 distinct diamond shapes—including elegant emerald and timeless oval cuts—to create a one-of-a-kind engagement ring.
What if my partner doesn’t love the design?
If you’re going to make this once-in-a-lifetime purchase, you want to give your partner a design they’ll truly love.
That’s why we offer the Proposal Ring Plan, where you propose with a temporary ring and choose the final design together afterward.
It’s also a perfect option for those short on time before the big moment.
Proposal Ring Plan : Propose now, design later
- Place the ring on your partner’s finger, capture the moment in photos, and speak your heartfelt words with confidence.
- Not sure about your design sense? Don’t worry—after the proposal, you can choose the final ring together.
- Concerned about “what if it doesn’t go well”? This plan is designed to ease those worries from the start.
If your proposal is successful and you purchase your engagement ring at DIALLURE within 6 months, the ¥35,000 will be fully credited toward the final ring—so nothing goes to waste.
This plan transforms your feelings into something beautiful, lasting, and truly meaningful.
What a Diamond-Only Proposal Can’t Deliver
In Japan, several brands now offer what's called a “diamond-only proposal” — a minimal approach where only the center diamond is purchased and presented in a box.
However, in reality—
- Since it isn’t set in a ring, you can’t place it on your partner’s finger
- Many find it underwhelming for photos or a meaningful proposal moment
- While the “ring box moment” looks good, it often lacks emotional impact
That’s exactly why DIALLURE created the Proposal Ring Plan—to offer a more thoughtful, memorable alternative.

Proposal Ring Plan – FAQs
Q. How much do engagement rings cost after the proposal?
In Japan, the average engagement ring budget is said to be around ¥400,000 for a 0.3ct diamond.
At DIALLURE, that same budget can offer you a 1ct lab-grown diamond ring or a 0.5ct natural diamond ring—an impressive upgrade in both size and brilliance.
Q. I don’t live nearby—can I still use this service?
Our Proposal Ring Plan is designed for couples to visit our Tokyo showroom together after a successful proposal to select their final engagement ring.
If visiting in person isn’t possible, we also offer a fully online experience: consult with us remotely and have your custom ring crafted and delivered right to your home.
Feel free to contact us via LINE or Contact form for personalized support.
Q. Do I need to return the proposal ring after using it?
If you purchase your engagement ring from us, we kindly ask you to return the proposal ring as part of our sustainability efforts. In that case, the full amount will be applied as a credit toward your engagement ring.
If you choose not to purchase your engagement ring from us, there is no need to return the proposal ring.
Q. I don’t know my partner’s ring size—what should I do?
The proposal ring is for presentation purposes only and is available in two sizes:
M (Japanese size 12 / US size 6), which fits most average finger sizes in Japan, and
L (Japanese size 16 / US size 8), for a more generous fit.
In most cases, M is a safe and comfortable choice.
Rest assured—your final engagement ring will be custom-crafted to your partner’s exact size.
