The 18k white gold Louella ring places an oval aquamarine blue sapphire at the centre of a petite trilogy. A pair of lab-grown diamonds flanks the gemstone, giving the design three distinct stones rather than a surrounding halo.

Aquamarine Blue Sapphire is the named blue centre of this version. Its oval outline lengthens the main stone's silhouette, while the diamonds remain separate accents. The sapphire colour belongs to the centre; the stones at its sides are specified as D/E VS lab-grown diamonds.

White gold provides a pale setting for the oval centre and its two diamond accents. The 1.70mm band is slender beneath the trilogy, giving the longer gemstone outline prominence. The three-stone form stays clear when viewed from above. The paired diamonds add detail on both sides, leaving the oval's uninterrupted face as the principal coloured surface of the ring.

Choose among four listed oval sizes, from 0.98ct / 7x5mm to 3.59ct / 10x8mm. The largest is marked made to order, and every label combines carat weight with a millimetre dimension. This allows the scale of the coloured centre to be judged alongside Louella's 1.70mm band and diamond accents. Both millimetre measurements help indicate the oval's shape.

ABOUT YOUR CENTRE DIAMOND

Lab-grown aquamarine sapphire gemstones

An aquamarine blue lab-grown sapphire offers a lighter expression of blue. Its softer colour can give an engagement ring a different character from a deeper traditional blue sapphire while retaining sapphire as the centre gemstone.

For someone drawn to pale, fresh blue tones, the colour can provide a gentle focal point or become more defined when surrounded by contrasting stones.

Aquamarine blue describes the colour

In this collection, aquamarine blue describes the colour of the lab-grown sapphire. It does not mean the gemstone itself is aquamarine.

Aquamarine belongs to the beryl family, while sapphire is corundum. They are different gemstone materials even where their colours may appear similar.

This distinction matters when comparing jewellery. An aquamarine blue sapphire ring should be understood and cared for as sapphire.

Choosing a lighter blue

A lighter blue can create a different impression from a more saturated sapphire centre.

Consider whether you want the colour to sit quietly within the design or remain unmistakably blue from a distance.

Compare the gemstone with the surrounding metal and any white accent stones. These elements can influence how delicate or pronounced the blue appears.

Choosing a setting around pale blue

Platinum or white gold creates a cool-toned palette around an aquamarine blue sapphire.

Yellow gold introduces warmer contrast, while rose gold combines the blue centre with softer pink tones.

A solitaire keeps the design simple. A halo provides a defined border, while a trilogy allows the relationship between the centre and side stones to play a larger role.

Shape and scale

A round centre provides symmetry, while an oval or pear creates a more elongated silhouette.

More angular outlines offer another way to frame a lighter colour.

Compare the gemstone’s dimensions with the band and setting. A fine band can give a softly coloured stone greater visual presence without requiring a more elaborate design.

Sapphire properties apply

Although the colour is described as aquamarine blue, the gemstone is sapphire and has sapphire’s material properties.

It is well suited to regularly worn jewellery but should still be protected from hard impacts and cared for as part of the complete ring.

A Lily Arkwright aquamarine blue sapphire ring brings together a softer blue colour with the durability and character of sapphire.
