The 4-prong solitaire: the perfect balance of value, presence and comfort
This 4-prong solitaire ring is designed for those who want a fine-quality diamond, certified by GIA, with a thoughtful and intelligent budget. It delivers an outstanding value-to-prestige ratio, combining a comfortable, durable setting crafted in Lausanne with diamonds carefully selected by our GIA-trained gemologist.
Two diamond sizes to suit your style: 0.50 ct or 1.00 ct
Two carat weights are available to match different preferences:
- 0.50 ct: ideal for an elegant, understated and accessible engagement ring that remains genuinely high-end.
- 1.00 ct: perfect if you want a stronger visual presence on the hand and a more impactful look, while keeping a refined, delicate setting.
Two GIA-certified qualities for an intelligent choice
You can also choose the diamond quality that best fits your expectations:
- H SI1: an excellent balance between beauty, brilliance and smart budgeting.
- F VS1: whiter and cleaner, for even more sparkle and a distinctly luxurious feel.
A setting engineered for comfort and durability
The 4-prong setting has been carefully designed to maximize both comfort and longevity:
- a slightly rounded inner shank for comfortable everyday wear,
- reinforced prongs that protect the diamond without overpowering it visually,
- an open gallery that allows light to enter the stone and enhance its fire.
A Lausanne-crafted favorite, appreciated for its finesse and honesty
Hand-assembled in our Lausanne workshop, this ring is one of our most appreciated models, both for its timeless design and for the transparent way it is priced: you are investing in the quality of the diamond and the craftsmanship, not in heavy marketing overhead.

Frequently asked questions
Is the diamond always GIA certified?
Yes. Every diamond comes with its original GIA certificate, detailing the 4Cs: carat weight, color, clarity and cut proportions.
What is the difference between H SI1 and F VS1?
H SI1 offers beautiful brilliance with a very smart price point. F VS1 is whiter and cleaner, with extra sparkle and a more luxurious overall impression.
How does 0.50 ct compare to 1.00 ct in this model?
The 0.50 ct option is perfect if you are looking for a refined, elegant and accessible engagement ring. The 1.00 ct option is ideal if you want a more noticeable diamond on the hand, with greater visual impact, while keeping a slim and balanced setting.
Is the setting comfortable for everyday wear?
Yes. The inside of the band is slightly rounded and the setting is designed not to snag easily, so the ring can be worn comfortably day after day.
What are the production times?
On average, allow 10 to 15 business days for us to craft the ring in your size and carry out all quality checks before shipping.
Can I see the ring or the diamonds before purchasing?
We can arrange a discreet appointment in Lausanne, or a video consultation with our gemologist to present the model and different diamond options.
