Product Description

Dramatic proportions and refined brilliance define this exceptional 3.00ct lab grown marquise diamond ring. Crafted in premium 18K white gold, the design showcases the centre stone's distinctive elongated form, with elegantly tapered points creating a striking silhouette across the finger.

Measuring approximately 16.0mm × 7.0mm, the marquise diamond delivers remarkable visual presence. Its extended profile draws the eye along the length of the stone, while brilliant-style faceting creates flashes of light and sparkle that emphasise its impressive scale.

Graded D/E colour with VS clarity, the diamond offers a bright, beautifully clean appearance that complements the crisp tone of 18K white gold. The simplicity of the surrounding design allows the unusual proportions and character of the marquise cut to remain the defining feature.

The diamond is independently IGI certified, providing professional verification of its assessed characteristics. Combining a substantial 3ct weight with one of the most distinctive diamond shapes, this ring is an exceptional choice for a statement engagement or significant piece of fine jewellery.
