Love the I'll-love-you-forever quality of diamonds, but fancy something a bit different for your engagement ring? Or searching for the perfect jewellery to add a pop of colour to you W-day look? Online jewellery emporium Seventy Seven Diamonds have added coloured gems to their collection of gorgeous adornments.

The oh-so-pretty natural hues – generated by tiny particles of elements like boron or nitrogen within the diamond – include blue, pink, red, yellow, black... in fact, there are several hundred colours as every one is formed differently by nature.

The stones are available in lots of pretty cuts – we're loving the vintage-look Asscher or girly heart shapes. You can choose a loose diamond online, or visit their showroom in London where you can have a bespoke piece made with the coloured stone of your choice. And if you prefer your diamonds classically clear, there are vintage-style and contemporary necklaces, earrings, wedding and eternity bands, in a range of precious metals to provide the perfect finishing sparkle to your W-day outfit.

So point your h2b in the direction of 77diamonds.com for your wedding-day gift (hint, hint...) or visit yourself to check out their range of serious bride candy.
