Aquamarine & Sapphire Ring

Dedicated to the design of sophisticated jewellery that tells a personal story for the wearer, Hattie Rickards Jewellery produces distinctly creative engagement rings, bespoke commissions and other personalised pieces with outstanding quality craftsmanship.

The octagonal cut is extremely similar to an emerald cut, and often very hard to tell the two apart. The main difference is that octagonal cut stones often have eight equal sides, rather than the emerald cut having a predominantly rectangular shape with short ‘corners’ making up eight sides.

Jewellery designers favour an octagonal cut gemstone for being a less common choice, as they have a geometric but classic shape. With a large table (the top, flat part of a gemstone when looking from above) this cut favours clear, coloured gemstones of high quality with few imperfections.

Gold is a naturally occurring metal with a warm, glowing finish when polished, and remains the most popular choice for engagement rings due to its natural beauty and hard-wearing strength.

Pure 24k gold is naturally a soft material, and considered too soft to create jewellery with, so it is mixed with small amounts of other metals to create an alloy.

As well as increasing the durability of the gold, adding alloys can also change the colour of the gold to produce rose or white gold, for example.

18k yellow gold is made up of 75% pure gold, and 25% alloy, which would usually include silver and copper.

18k rose gold is made up of 75% pure gold, 22.2% copper, and 9.2% silver.

18k white gold is made up of 75% pure gold and 25% palladium or platinum.
