Lab Grown Diamond Engagement Ring

Our engagement rings centre around an ethically and sustainably made lab-grown diamond. Just like a mined diamond, lab grown diamonds provide the same quality and consistency. This means they will never fade, damage or scratch. With a lab grown diamond, you get the same stone without worrying about ethical attainment and environmental damage done in the process. If you’re still curious, learn more here.

Trilogy Engagement Ring

With a classic, elegant shape, an oval engagement ring will never go out of style. Add two shoulder stones and you create a ring that is memorable, unique and a heirloom in the making. We chose trilliant stones to compliment this emerald centre stone however round, tapered baguettes, trillion, pear and half moon stones also work beautifully. 

Engagement Ring Metals 

Our Engagement Rings come in three different metals: 18ct Yellow Gold, 18ct Rose Gold and 18ct White Gold. The metal is thoroughly hand-polished for a smooth, shiny finish. Yellow Gold has a subtle, warm colouring, Rose Gold has a pinkish tint and White Gold looks similar to a warm silver.

How to Find Your Ring Size 

One size does not fit all, and with a purchase as meaningful as an engagement ring, you want to make sure to get it right. Our Size Guide will help point you in the right direction, and if you need more guidance please don’t hesitate to contact us for help.

Diamond Sizes by Carat 

The size of the diamond translates into a carat size and the final carat size depends of the depth of the stone.

5mm x 7mm = 0.7 - 0.8 carat
6mm x 8mm = 1.1 - 1.2 carat
7mm x 9mm = 1.5 - 1.7 carat

Kate & Kole pieces are made-to-order, meaning you’ll be left with something truly one-of-a-kind. If you’re interested in customising your ring further, with a different stone, band, setting, or size variation, read more about the process here
