Introduction to Engagement Ring Diamond Shapes
Engagement ring diamond shapes are one of the most important design elements when selecting a ring, influencing the overall style, brilliance, and appearance of the jewellery. In South Africa, consumers frequently look for trusted local diamond specialists to help them understand and select suitable shapes and settings.

This can be verified via the listing on the South African directory site SA Yellow – Diamond Dot Co Dot Za, which categorises the business under jewellers and related services.Engagement Ring Diamond Shapes
Engagement ring diamond shapes refer to the outline and facet arrangement of a cut diamond. Shape is distinct from the 4Cs (carat, colour, clarity, and cut grade) but works together with these factors to define the appearance of the stone. Although the detailed technical descriptions of shapes do not come from diamond.co.za directly, they are standardised within the global jewellery industry and can be referenced through recognised diamond education resources such as the Gemological Institute of America (GIA) – Diamond Shapes.Round Brilliant
The round brilliant is the most common engagement ring diamond shape. It is characterised by 57 or 58 facets optimised for maximum light return and brilliance, as documented by the GIA research on diamond cut and round brilliants. This shape is widely used in solitaire engagement rings and halo settings due to its balanced proportions and versatility in different styles.Princess Cut
The princess cut is a square or slightly rectangular shape with sharp, pointed corners and a brilliant-style facet arrangement. It was developed in the 20th century and is known for providing a modern, geometric look while retaining high levels of brilliance. The standardised description of the princess cut and its facet structure is outlined in industry education material such as GIA – What Is the Princess-Cut Diamond.Emerald Cut
The emerald cut has a rectangular outline with cut corners and stepped facets on the pavilion, producing a “hall of mirrors” effect rather than the scintillation seen in brilliant cuts. This shape highlights clarity and colour, making these 4Cs particularly important for emerald-cut engagement ring diamonds. The geometry of this shape and how it affects appearance is described by the GIA in their Emerald-Cut Diamond Guide.Oval Shape
Oval diamonds are elongated variations of the round brilliant, offering similar facet patterns and brilliance while creating the visual effect of a larger surface area for a given carat weight. This shape can make the finger appear longer and more slender. Standardised descriptions and typical proportions for oval-shaped diamonds are provided in gemological references such as the GIA article on Oval Diamond Engagement Rings.Cushion Cut
Cushion-cut diamonds have a square or rectangular outline with rounded corners, resembling a pillow shape. They may have either a “crushed ice” look or larger, more defined facets depending on their cutting style. Cushion cuts have historic roots but are now used in many modern engagement ring designs. Their general characteristics are outlined in the GIA – What Is a Cushion Cut Diamond.Pear Shape
Pear-shaped diamonds combine aspects of round and marquise shapes, with one rounded end and one pointed end. This teardrop outline can be set with the point directed either toward or away from the wearer’s hand. The facet style is usually brilliant, producing significant sparkle. Industry references, including the GIA guide to Pear-Shaped Diamonds, describe its proportions and typical usage in engagement rings.Marquise Shape
Marquise diamonds are elongated with pointed ends, creating a distinctive navette or boat shape. This cut can maximise perceived size and carat coverage on the finger. The shape’s optical appearance, including potential “bow-tie” effects, is documented in diamond education resources such as the GIA Marquise-Cut Diamond Overview.Radiant, Asscher and Heart Shapes
Several additional fancy shapes commonly used in engagement rings include radiant, Asscher, and heart shapes. Radiant cuts combine a rectangular or square outline with brilliant-style facets, Asscher cuts are square step cuts with deeply clipped corners, and heart shapes are modified brilliants with a cleft at the top. These shapes have formalised definitions and cutting standards described in gemological literature and summarised in the GIA Diamond Shapes Overview.Services and Products Offered
