Ideas for speciality shaped diamonds

Side stones. Baguettes, tapered baguettes, half moons, shields and trapezoids are classic side stones for three-stone engagement rings.

Personal jewellery. Letter, star, flower and animal shaped diamonds make meaningful initial pendants, earrings and gifts.

Modern solitaires. Kite, hexagon and shield cuts give a bold, geometric look for an unconventional engagement ring.

Browse all loose lab-grown diamonds, or see our rose cut, vintage cut and triangle cut diamonds.

Frequently asked questions

Can I see these diamonds in your London store?

Our London store displays finished jewellery and a smaller selection of gemstones. Our loose diamonds are held at our workshop, so they are not on display in store.
