The seven sapphires on this ring aren't set in a straight line. They follow a gentle wave, so each stone catches the light from a slightly different angle. It gives the top of the ring a sense of soft, constant movement.

A slim, polished 14K yellow gold band holds seven deep blue sapphires. Each round stone is secured by four tiny prongs, and they're arranged in a single, undulating line, not a straight one. This gives the top of the ring a soft, scalloped profile against your finger. The rest of the band is smooth and simple, letting the rich colour of the stones stand out.

This ring is made from solid 14K gold, not plated. It's an alloy of 58.3% pure gold, which means it has that rich, warm colour but is also strong enough for you to wear every day without worrying about it bending out of shape. The stones are lab-grown sapphires. They have the exact same hardness and chemical makeup as mined ones, so they're incredibly durable. But this way, we can guarantee a perfectly matched, deep royal blue colour across all seven stones.

You'd pick this ring if you want a colourful stacking band that isn't perfectly straight. The gentle wave of the sapphires adds a bit of movement and makes it more interesting than a standard eternity band. It’s thin enough to stack but has enough presence to wear on its own.
