Center Stone Carat

Carat measures the diamond's weight.

Carat is not exactly the same as visible size, but higher carat usually means a larger-looking centre stone. A 1.50 ct stone is a popular balance between presence and elegance.

0.50Delicate and subtle

1.00Classic everyday proportion

1.50Strong presence with balance

2.00+More statement-like appearance

Metal

The metal is the body of the ring.

It influences colour, weight and durability. 18K gold has a richer precious-metal content, 14K gold is slightly harder in daily wear, and silver offers a lighter entry point.

14K GoldWarm golden tone with everyday resilience.

18K GoldRicher colour and more luxurious precious-metal content.

SilverBright white tone and lighter investment level.

Side Stones Included

Side stones are smaller diamonds beside the centre stone.

They can make the ring feel more radiant and detailed. Choosing “No” keeps the design cleaner and more minimal.

Color

Diamond color measures how white or warm the stone looks.

D is the most colourless. As the scale moves toward J, a softer warm tint becomes more visible. Many clients choose F or G for an elegant white look with balanced value.

Clarity

Clarity describes how clean the diamond is internally.

VVS stones contain extremely tiny inclusions. VS stones can still appear eye-clean in many cases, while offering more flexibility in budget.
