Use an existing ring that fits on the ring finger
Measure the internal diameter (mm) of the ring
We strongly recommend having your ring size professionally measured for the most accurate fit. Ring sizing is a personal preference. Rings should have some resistance going over the knuckle and feel snug but comfortable at the base of your finger.
Size will fluctuate with factors such as climate and hydration. Measure your finger at different times to get an average. Band thickness also impacts fit. Wider bands and stacked rings will likely require sizing up.

In jewellery, stone shape refers to the physical form or outline of the diamond or gemstone, which impacts its overall appearance and style. Often confused with cut, common shapes include oval, round, emerald, cushion, and more. Each shape highlights different aspects of the gemstone's hue, brilliance and fire. When selecting a gemstone, consider personal style and how the stone's shape will complement the setting and overall design of the piece.
Colour in a diamond is a natural phenomenon caused by trace elements during its growth. The D to Z scale is the industry’s most widely used grading system, evaluating diamonds based on their colour.
Subtle colour differences can impact a diamond’s value, even between stones of the same carat and clarity, though distinctions are often unnoticed by the untrained eye between D and G.
Band width refers to the width of the ring’s shank, which is different from its height. Most LOUISE JEAN engagement rings have widths ranging from 1.6mm to 2.5mm
While custom widths are available, there are minimum width requirements to ensure structural durability, based on factors like design, ring size, and stone size.
Our team is happy to assist with any inquiries about band widths and can help ensure visual balance and proportionality for your design.

During the diamond growth process, internal impurities called inclusions are formed. Clarity grading evaluates their type, position, and visibility, ranging from Flawless (F) to I3.
Aiming to select diamonds that are eye-clean, with inclusions too tiny to be seen without magnification, provides the best balance of value and quality.
Clarity doesn't affect brilliance or sparkle, and as long as a diamond is eye-clean, clarity gradings are indistinguishable to the naked eye.
The cut of a diamond refers to the facet arrangement, which impacts its light performance, fire, brilliance, and overall beauty. Cut is one of the most important yet misunderstood aspects of a diamond. Cut is graded by measuring angles and facet sizes. Inferior cuts can cause light leakage or dark zones, resulting in a dull diamond or severe bowtie.
Only round diamonds have a specific cut grading on their certificate, as they follow standardised guidelines for proportions. All other diamonds, known as fancy shapes, do not have a universal cut grading but may have their polish or symmetry assessed. Cut grading can only truly be assessed by inspecting the diamond itself, not the certification.
All diamonds, regardless of shape or carat, have unique dimensions. This refers to the length, width, and depth of each stone, measured in millimeters. Two diamonds of the same shape and carat weight can look very different to the eye due to variations in their proportions. Dimensions affect not only the diamond's size and visual appearance, but can impact their cut quality and sparkle.
Finish refers to the surface texture of a ring. We offer two finishes for our unisex ring designs.
High Polish
A sleek, shiny finish that creates a smooth, reflective surface, offering a timeless and elegant appearance.
Brushed Finish
A soft, matte finish with fine linear texture, achieved by hand-brushing the surface for a subtle and modern effect.
Both finishes can be applied to all metal colours and karats. It's important to note that both metal finishes may show wear over time and will require re-finishing to maintain their appearance.
High Polish
Brushed
Pavé (pronounced "pah-vay") is a French term meaning “paved”. Pavé designs can vary in stone sizes and widths. Different pavé techniques, such as variations in the number and shapes of claws, can change the visual effect of the stones or designs.
1/2 Pave
A 1/2 pavé band features stones set halfway around the ring.
3/4 Pave
A 3/4 pavé band has stones set three-quarters of the way around the ring.
The number of stones set will vary depending on the ring size. If you're concerned about your rings spinning, a 3/4 band offers more coverage. We do not offer full pavé bands, as stones on the inside of the hand are more prone to damage.

Round Solitaire Designs

4-claw setting
6-claw setting
Orientation refers to the angle at which the stones, often the centre stone, are set. We invite you to customise the orientation of the focal stone to create a unique design. While the most common setting is portrait (north-south), other popular options include east-west, a compass orientation, or even a custom angle. The orientation affects the appearance of the diamond shape, and can also change the way the ring sits and covers the finger.
Portrait
The most common choice in ring settings, stones are set vertically, with a portrait orientation (north-south)
East-West
For visual appeal and increased finger coverage, elongated stone shapes can be set horizontally in an east-west orientation. Available in most setting styles, including trilogies on request.
The ratio of a diamond refers to the proportion of its length compared to its width, calculated by dividing length by width. A lower ratio results in a more plump, rounded stone, while a higher ratio gives a more elongated, slender appearance.
The ratio significantly impacts the visual appeal of a diamond and is a matter of personal preference. Square and round diamonds typically have a ratio of 1.0, while other shapes vary, with some ratios being more common than others.
Oval Ratio
Cushion Ratio
Emerald Ratio
Marquise Ratio
Pear Ratio
Radiant Ratio
Round Ratio
Asscher Ratio
At LOUISE JEAN, we craft high-quality pieces using only precious metals: 9K, 14K, and 18K Yellow, Rose, White Gold, and Platinum. Our pieces are solid, with no plated or vermeil designs. Each metal karat has unique characteristics, including colour, hardness, and durability, to suit your aesthetic and lifestyle preferences. Our gold is sourced from a trusted supplier, certified by the Responsible Jewellery Council, and ensures ethical practices of Australian metal sourcing.
Engraving can be added to any LOUISE JEAN ring. Use letters, numbers and roman numerals to personalise your piece, with up to 15 characters (including spaces). Engraving will be placed on the inside, at the base of your ring. Choose from three fonts to reflect your personal style. Engraving will appear exactly as entered so please be sure to double-check the details.
Note: Character limits may vary depending on ring style and size. Rings with engraving may be subject to reduced resizing parameters.
A hidden gem is a personalised touch that can be added to any ring, engagement or wedding. Available in coloured diamonds, gemstones, and many birthstones, up to 3 inlay gems can be included. Flush set on the inside of the band, they are typically positioned on the side of the shank, to the side of any stones or settings.
Inlay gems can also be placed on the outer surface of our Classic Ring, Cuff Ring, and Signet designs. Please leave a note at checkout with your preferred gem placement, and we will endeavour to accommodate your request while ensuring the structural integrity and durability of the piece. Our team will reach out to confirm the placement of gems before proceeding with production.
