Our Diamond Expertise

The value of a diamond lies in its phenomenal creation billions of years ago, its enduring strength, and its timeless beauty. Formed deep within the earth, diamonds are almost as old as life itself and are older than most stars in the sky. They are a miracle from nature – a special piece of infinity to be passed down and cherished from generation to generation.

Since 1980 we have specialised in creating one-of-a-kind pieces of handmade jewellery and engagement rings featuring the finest quality diamonds and gemstones.

From the eye-catching central diamond to the sparkling side stones, the Hirsh family pride themselves on personally and responsibly sourcing our exquisite diamonds and gems from trusted suppliers that we have worked with for generations.

In addition, our suppliers fully adhere to the esteemed Kimberley Process, ensuring that our diamonds are conflict-free and ethically sourced.

You will have heard of the 4 C’s, of which our in-house gemmologists are experts in: Colour, cut, clarity and carat, however we would like to add a few more C’s to this equation. Care, consideration, creativity, and craftsmanship.

We’re proud to say that all of our round brilliant diamonds are triple excellent cut – the highest quality possible. Each of our triple excellent cut diamonds above 0.20 carats are accompanied by a GIA certificate. Likewise, our fancy shape diamonds above 0.50 carats are also accompanied by a GIA certificate. The Gemmological Institute of America (GIA) is the utmost authority on diamond grading worldwide.

At Hirsh, we go above and beyond to create beautiful, unique jewellery and engagement rings with the guaranteed assurance that we only use the very best quality diamonds and gemstones for each and every piece we create.
