Choosing a Lab Grown Gemstone Engagement Ring
A coloured gemstone engagement ring gives you the freedom to choose a centre stone for its character and colour as well as its shape. Compare oval gemstone engagement rings, with their softly elongated outline, against round gemstone engagement rings for a more symmetrical silhouette. Deep blue sapphire, vivid ruby, green emerald and colour-changing alexandrite create quite different impressions, even in the same setting. Lab growth describes how the gemstone is made; it does not mean that all gemstone species have identical properties.
Begin with colour and everyday practicality
Think about whether you prefer a subtle pastel shade or a saturated centre stone, then compare actual pieces under more than one light source. Sapphire and ruby are both varieties of corundum, while emerald belongs to the beryl family and has different care considerations. Gemstone hardness is only part of durability; inclusions, setting height and daily habits are also important.
Choose the setting around the colour
A gemstone solitaire engagement ring keeps the centre stone's colour clear, while a diamond halo creates a bright frame. Yellow gold can warm the overall effect; platinum and white gold create a cooler contrast. A bezel or appropriately placed claws may help protect exposed edges, depending on the cut. Compare blue sapphire engagement rings, lab grown emerald engagement rings and ruby engagement rings to see how each colour works with different settings.
Care, colour and the choice of centre stone
Gemstones are not interchangeable simply because they share a colour. Sapphire and ruby belong to the corundum family, while emerald and alexandrite have different physical characteristics and care needs. Ask what the selected lab grown stone is, rather than relying on its trade colour description, and consider how often the ring will be worn. Some designs benefit from a protective setting, particularly if their centre stone is exposed at the corners or edges.
Our consultants can help you choose a gemstone and setting together, with advice on wear, cleaning and matching a wedding ring to the final design.
