A wedding band beside an engagement ring
We invite clients in London to discover the Maison through a private selection of bridal jewels and High Jewelry. For a wedding band destined to sit beside an engagement ring, a few millimetres of clearance can change the character of the pair.
We present selected Just Brilliant creations through multibrand retail partners. Our international advisors welcome private enquiries and can introduce the collections personally.
A private viewing in London
At a bridal consultation, an advisor can consider the underside of the engagement ring as carefully as its face. The gallery determines how closely a second band may sit. We can explore straight and contoured designs and confirm which pieces may be seen privately in London.
Handmade in Valenza, Italy
A Just Brilliant creation is made by hand in Valenza, Italy. Our New York origins find expression in precise silhouettes, from the fine edge of a solitaire to the sweep of a necklace. White, yellow and rose 18K gold appear throughout the collections. For a particular jewel, your advisor can explain the choice of metal and the details of its construction.
Engagement rings and wedding bands
The hidden halo of an emerald-cut ring is most apparent from the side. The sweep of a curved band can make room for the setting and leave an uninterrupted line around it. The chosen ring size and the exact shape of both profiles govern the final fit.
Our engagement rings and wedding bands can be considered together. In the men’s wedding band collection, width, finish and the curve against the finger deserve the same attention. The Ring Size Guide is available before a personal fitting.
Soleils Majestueux Diamond Studs
The Soleils Majestueux studs bring yellow and white gold together around two yellow centre diamonds. Each centre weighs 3.04 carats. Baguette and oval diamonds in the outer frames give the pair its striking alternation of straight and curved edges.
The two Fancy Vivid Yellow centre diamonds each weigh 3.04 carats. Their combined centre weight is 6.08 carats. Yellow gold surrounds each centre and white gold defines the outer frame.

Jewelry for an occasion
Beyond the bridal pair, diamond earrings can repeat a detail from the rings without matching them exactly. The rectangular outline of a baguette, for example, can recall an emerald cut while changing the scale and rhythm at the ear.
Discover our earrings, necklaces and pendants, bracelets and rings, or consider a selection from the bridal jewelry collection.
Diamonds and coloured gemstones
The origin of a diamond is one part of its identity. Cut, colour, clarity, weight and face-up measurements allow a more complete comparison. Our advisors can guide you through natural and lab-grown options for the design you prefer. The Maison’s Diamond Guide is available to explore before a consultation.
Where a coloured stone is preferred, our advisors can introduce emeralds, rubies and sapphires. The documentation for the particular stone sets out the origin or treatment details available for it.
Create Your Ring and personal commissions
In Create Your Ring, a setting and a diamond are chosen in sequence and brought together for review. It is a way to explore an existing design at your own pace. A personal commission begins with a conversation about the intended jewel. The Maison can advise on its proportions, the choice of stones and the work required.
Quotations and making time
For a finished jewel, an advisor can confirm availability and the price in the applicable currency. A made-to-order piece follows its own schedule. Where a wedding or another occasion determines the date, the Maison can consider the making time, any engraving and the proposed arrangements after dispatch together.
The Maison’s shipping information and exchange terms apply to direct purchases. For a purchase through a retail partner, your advisor can clarify the terms for that selection.
Personalization and care
An inscription, a change of size or the renewal of a finish depends on the construction of the piece. Our care guidance explains how to look after a jewel between services. For a fitting, repair or an enquiry about the Maison’s warranty, an advisor can establish the appropriate arrangements for the creation and its purchase channel.
Questions for the Maison
Can the Maison work with my UK ring size?
Your advisor can interpret a UK letter size and review its equivalent for the width and profile under consideration. A broader band may feel different from a fine solitaire.
May we discuss an inscription before choosing the band?
Yes. Interior space depends on the width, size and construction. The Maison can advise on placement and confirm the proposed inscription before engraving begins.
What accompanies a Just Brilliant diamond creation?
For individual lab-grown diamonds above 0.5 carats, the Maison provides an IGI report. Individual natural diamonds above 0.5 carats are accompanied by a GIA report. The JB-created diamond range has a Just Brilliant certificate. Your advisor can explain the documents supplied with the particular jewel.
How can I verify a creation after purchase?
The Maison’s Creation Passport uses the creation number supplied with your jewel. It identifies the finished piece. An individual diamond grading report describes the stone to which that report belongs.
How will my UK ring size be considered for a London viewing?
A UK letter size gives our advisor a point of reference. The inside diameter and width of the chosen band help refine the fit. Our Ring Size Guide includes inside measurements, and the Maison can confirm which band profiles may be presented in London. Consult the Ring Size Guide.
