Select your preferred setting style from our signature solitaire designs. The Classic and Ceremonial solitaire appear very similar from above however they have slight differences in their design.

Our Classic Solitaire (right) features a sweeping cathedral band that tapers as it meets the rail which gives the band a finer look. The Ceremonial Solitaire (left) is slightly more refined in nature, showcasing your diamond of choice in a minimal basket setting.


Our passionate team of gem experts procures our extensive inventory of diamonds through a local and global network of stone partners who align with our focus on ethical sourcing and practices.

Our criteria and strict quality parameters ensure every diamond in our inventory are 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).


Carat is the measurement of weight for a diamond and primarily what determines and influences value. Diamonds come in various carat weights, and as the weight increases, the more valuable and rarer they become.

Two diamonds of equal shape and carat weight can have a considerable price difference. When selecting your desired carat, remember that a diamond’s value is also determined by a combination of all the 4C’s, and not just the carat.

Consider the length and width mm measurements listed for each diamond to understand the size and how large the diamond will appear when viewed from above.


The GIA’s D to Z colour-grading scale is the industry’s most widely accepted grading system for diamonds. It is essentially the evaluation of diamonds based on the presence of colour.

The scale begins with the letter D, which represents the highest grading and a completely colourless stone. The letters on the lower end have more presence of colour and can often have a yellow tinge. Between grades D to G, colour distinctions are very subtle and often unnoticeable to the untrained eye.

At LOUISE JEAN, we source D to H colour grades especially for our inventory to guarantee bright, high-quality stones. These diamonds are within the colourless and near-colourless range exclusively, with the exception of Champagne, or fancy coloured diamonds.

During the diamond growth process, internal impurities and imperfections are formed, otherwise referred to as inclusions. The clarity grading of a diamond indicates the degree of inclusions that are present, and how easy they are to see.

The clarity grading scale of a diamond ranges from IF (Internally Flawless) to I3. At LOUISE JEAN, we ensure that all of our diamonds are eye-clean, ensuring no visible inclusions to the naked eye. When inclusions are present in our diamonds, they are too insignificant to be seen by anyone other than a trained diamond grader under magnification.

Cut is one of the most important C’s of a diamond, but unfortunately can also be one of the most confusing and misunderstood.

The Gemmological Institute of America (GIA) grades the cut by precisely measuring the angles and sizes of the facets of a diamond. These include the diamond’s table, depth, girdle, pavilion, crown, and culet. Polish and symmetry can also play a minor role. All these factors come together to determine the cut grade of the diamond.

Only diamonds that present a high excellence of cut quality, polish and symmetry are procured for our inventory. All of these diamonds are assessed on their overall brilliance, light performance and visual beauty.


Our designs can be crafted in 18K yellow gold, rose gold, white gold, or platinum.

Additional Options

Select additional design options to customise your design, including a diamond pavé band and two-tone setting.

A pavé band features micropavé diamonds which are delicately set along the band for additional sparkle.

A two-tone setting features a band that is crafted in your preference of yellow or rose gold, with a centre stone framed in platinum setting. Please note this option is not available for bands crafted in white gold or platinum. 

Band Shape

We create our engagement rings with a standard 1.6mm half-round band. This achieves the best balance of a fine and dainty aesthetic, while maintaining the structural integrity that is essential for a lifetime piece. 

The half-round profile gives the appearance of a traditional round band, whilst offering a comfort fit for wearing and stacking. If you would like to consider other band profiles for your piece, please contact us.

Please note, our wedding band styles are also created in our standard half-round band profile.

Ring Size

Please see our Ring Size Guide for helpful hints to determine your ring size. If you need to convert your ring size, please use our Ring Size Chart.

We understand you may not get it right the first time. We offer one complimentary resize* for all engagement rings for 6 months from the date the ring is received.
