Three Stone

This ring features a blue-green moss agate set in a timeless three-stone style. This style has plenty of symbolism. Each stone represents a phase in your relationship – your past, present and future. The centre stone symbolises your future, making it the most prominent stone. In this design, two diamonds flank the centre agate, in a twist on the traditional three-stone style.
Princess Cut

Princess cut diamonds are a time-honoured classic. That doesn’t mean that they have to be set in a conventional ring design. In this modern geometric take, an East-West design transforms the princess cut agate into a geometric design. Tiny pave diamonds are set on the top point, adding additional sparkle to this ring and turning it into something unique yet simple.
Orange Oval

Agate is most commonly associated with warm orange tones. Slabs of agate feature various shades of cream, orange and brown. In this ring, an oval orange agate takes centre stage. The stone is not faceted, with an opaque, shiny look. A halo of diamonds surrounds the stone.
Rosy Ballerina

If you love feminine styles such as ballerina rings, you’re sure to love this design. Set on a rose gold band, a smooth oval lace agate is flanked by smaller diamonds, like a tutu. It is this design that gives the ring its name. The combination of rose gold, blue-green and clear diamonds results in a truly unique ring.
Pink Cushion

In this ring design, a cushion-cut agate in muted, opaque pink is set on a diamond-studded band. The band has a channel setting, with pave diamonds set into the band. If you love the idea of a mixed stone ring but you prefer more subtle styles, this one is ideal.
Black Halo

Agates come in all colours, including black. Black agate is very similar to other black stones, including diamond and onyx. The agate gives the stone a smooth appearance, while facets catch the light. Four diamonds on the top, bottom and either side add more sparkle, while a pave band helps this ring shine even further. A cool-toned metal band is perfect for this ring.
Side Stone

Side stone rings are similar to three-stone rings, however, they come in a variety of designs. In this ring, bezel-set diamonds flank the centre agate stone. These marquise cut diamonds give the illusion of leaves, helping to frame the centre stone to perfection. Set on a rose gold band, the effect is feminine, pretty and interesting with a balance of colour.
Open Band

White agate has a pearly hue that is opaque without being dull. This design features an open band, with two small agates on either side. Tiny pave diamonds run along the band, leading up to the agate tips on each end. This ring works well in rose gold but would be equally beautiful in yellow gold or platinum.
