If you’re new to the world of diamonds, finding something for the perfect proposal can seem like a daunting task.
We’re with you every step of the way, from choosing ethically sourced diamonds to crafting them into unforgettable jewellery.
Here are some key questions about our 0.5 carat engagement rings:
A 0.5 carat diamond is an appropriate size for an engagement ring. It is around 5.25mm in diameter so is only just over 1mm smaller than a 1 carat diamond. If you’re on a tighter budget and you’d like to get more for your money, we’d recommend choosing a stone with an elongated shape. Pear, oval and marquise shapes all appear larger for the same weight as a round brilliant-cut.
A diamond of between 0.1 to 0.4 carats is often considered small. However, there is no clear answer about whether they’re too small for an engagement ring. Ultimately it is a matter of personal preference. Some may prefer understated and minimalist diamond rings, while others may seek out our exquisite craftsmanship for a show-stopping centrepiece. Whatever your choice we’re on hand to support and guide you every step of the way. Find inspiration from our stunning selection.

What colour is a diamond? Many say they’re colourless, however, look closely and most contain subtle tints of yellows, soft pinks and rich browns. Truly colourless diamonds are known as white diamonds and are extremely rare and the most valuable. Diamond colour is graded from D to Z – D being the whitest, most colourless diamond and Z containing noticeable yellow, brown or pink tints. The letters D to Z represent a range of colour based on a combination of tone, lightness or darkness and saturation.
Cut
Diamond cut refers to the arrangement of a diamond’s facets. A diamond’s cut is often mistaken as meaning its shape (oval, pear, etc), but a diamond’s cut grade is actually about how well the facets interact with light.
Polish
Polish refers to the overall smoothness and condition of the diamond’s surface. It’s rare for a diamond to have a perfect polish. More often, they have tiny imperfections not visible to the naked eye.
Symmetry
Symmetry refers to how well-aligned the diamond's facets are. Symmetry, on the other hand, refers to the exactness of shape, overall outline, placement and alignment of individual facets.
The gradings provided by the GIA go from poor to excellent. If you select an SI clarity, we will provide Very Good cut, polish and symmetry. If you select a VS1 clarity, we will provide Excellent cut, polish and symmetry.
