Our Story

We can help make your special moment, truly memorable.

Though diamonds are a girl’s best friend and the classic choice for an engagement ring, colored stones are a trend that continues to show up on many a celebrity’s ring finger. Opting for a colored stone is a fresh take on the traditional engagement ring, and the candy colored sparklers are unique and beautiful. Though many have tried the trend, a few specific engagement rings have stood out.

Our Workshop

Take a look inside our workshop and learn how we create timeless pieces of bespoke jewellery. Each ring is expertly made using the finest materials, gemstones and diamonds.

The Start to Finish Process

Have you ever wondered what really goes on in a jewellery workshop? Let’s go behind the scenes in the Diamond Boutique workshop to learn more about the jewellery making process and how we create the perfect piece of fine jewellery.

Step 1

Computer Aided Design

The process starts with our in-house team of skilled CAD designers. Each piece is expertly modelled using the latest technology capturing the delicate details and flourishes, which is at the heart of every Diamond Boutique piece.

Step 2

Wax Model

At this stage, the CAD design is used to create a wax model using a specialist wax prototype machine. This wax piece is then used for ‘loss wax’ casting. The end result is your design created in the metal of your choice.

Step 3

Rough Casting

This is where the magic begins. Our master goldsmith will begin the process of cleaning the rough casting, removing any unnecessary residue. Once the piece is cleaned it is ready to be finished by hand.

Step 4

Stone Setting

Following the cleaning process, the precious stones are set into the mounting by hand. This process is carried out by our expert setter and takes time to complete to ensure each stone in the piece of jewellery is perfectly set.

Step 5

Polishing & Finishing

The last step in the jewellery making process is polishing and finishing. The polishing is a multi-stage process, whereby the metal is buffed by hand and machine to achieve a high polish finish.

Step 6

Quality Check

We take the quality check process very seriously and are dedicated to ensuring the piece is finished to a high standard. Every aspect of the ring is checked including the metal appearance, quality of the diamonds or gemstones, the stone setting and overall finish of the ring.

Your Bespoke Journey

Our easy, transparent custom design process will ensure that in just four easy steps, you can have the exact ring you want, whatever the design.

Step 1

Discuss Your Design With Us

Do you have a design in mind but can’t find what you’re looking for on our site?

You don’t have to be an expert at writing or drawing to communicate what you would like – we don’t call our service “Art of the Possible” for nothing.

Step 2

The Sketch

Bringing your vision to paper. We’ll provide a free ring design based on your initial idea allowing you to visualise your idea.

A truly collaborative approach, we will continue to tweak your design until you are 100% happy with the design.

Step 3

The Render and Video

See it in 3D. Once the design is finalised we can provide you with 3D renders, a 3D animation or both. All you have to do is ask.

At this stage you will be able to visualise the design in colour, bringing you one step closer to the finished ring.

Step 4

We Bring Inspiration to Life

At this stage, we take over and use our expertise to craft the perfect piece of jewellery for you.
