Diamond Shape

At LOUISE JEAN, we have an extensive inventory of laboratory-grown and natural diamonds. Each diamond is sourced through a local and global network of suppliers who align with our focus on ethical sourcing and practices.

Our criteria and strict quality parameters ensure every diamond in our inventory is selected for its superior beauty and excellence. When choosing the perfect diamond for you, it is important to consider a combination of the 4C’s (carat, colour, clarity, cut). Learn more about our diamonds here.

Signature Designs

Select your preferred setting from our Signature Engagement styles. All our designs are high-profile, to allow for ease of stacking.

The Classic and Ceremonial solitaire appear very similar, however, they have slight differences in their design.

Our Ceremonial Solitaire is beloved for its minimalistic nature, showcasing your selected diamond in an elegant basket setting.

Our Classic Solitaire features cathedral shoulders that slightly taper as they meet the rail of the setting. A perfect juxtaposition of when traditional meets modern.



Our engagement designs are crafted in 18K yellow gold, rose gold, white gold, or platinum.

Band Profile

We have three signature band profiles. Half Round, Square Edge and Knife Edge.

The half-round profile is our most requested band. This gives the illusion of a rounded band from the top, but with flat sides for ease of stacking.

The square-edge profile is as the name suggests a squared band. This provides a clean modern look. 
This option is not available for our Classic Solitaire setting.

The knife-edge profile features a subtle 'knife' top and flat sides (like our half-round band) to accommodate stacking. This adds a slightly edgier and unique look, compared to a more traditional profile. 
This option is not available for our Classic Solitaire setting.

Please note, our wedding band styles are created in our standard half-round band profile. Additional costs may apply to customise the band profile on these designs.

Band Width

Many of our Signature engagement rings can be crafted in your preference of a 1.6mm, 1.8mm or 2mm band width. For centre stones 1.5ct and larger we recommend a width of 1.8mm or 2mm. This achieves the best balance of a fine and dainty aesthetic while maintaining the structural integrity that is essential for a lifetime piece. 

Please see below for our band width options in selected styles:
Ceremonial Solitaire & Amira: Available in 1.6mm, 1.8mm & 2mm.
Classic Solitaire: Available in 1.8mm & 2mm only.
Please note, our Knife Edge Band Profile is available in 2mm band width only.


Pavé Options

A pavé band features melée diamonds which are meticulously set along the band for additional sparkle. Available in either a 1/2 pavé (left) or 3/4 pavé (right).


Select additional design options to customise your design, including two-tone and claw options (Round solitaires only).

A two-tone setting features your selected stone framed in a platinum basket, and crafted with your band preference of yellow or rose gold. Please note, Two Tone is not available for bands crafted in white gold or platinum.

For Round Classic Solitaire & Round Ceremonial Solitaire, you have the option of selecting a 4-claw or 6-claw setting.


Hidden Gem

An inlay diamond or gemstone is a perfect way to add a personal touch to your Louise Jean piece. You can choose up to 3 hidden gems. These can represent something personal to you, such as your partner's or children's birthstones. Or a blue sapphire to honour the 'Something Blue' tradition.

For engagement rings, we set the hidden stone on the inside of the band directly below the setting. This is to avoid certain limitations when resizing. If more than one gem is chosen, the stones will be centred under the setting.

Ring Size

All LOUISE JEAN engagement rings and wedding bands are handcrafted to order and can be made to any size requirements.

Our rings are made to Australian ring sizes, based on an alphabetical scale from F - Z. These letters correlate with the internal diameter of the band, measured in millimetres. The difference from one ring size to the next is a matter of 0.2mm. The difference between a ring that fits and one that doesn’t could be just 0.4mm.
