As one of Perth’s leading jewellery stores, JIRE offers a large collection of wedding jewellery – specialising in diamond and pearl jewellery.

We select all our jewellery ensuring exceptional quality: cut, colour, and clarity.  (We don’t just pick the ones that look pretty!)

There’s a lot that goes into selecting our jewellery. We’ll explain how we do this through the 4Cs of Diamonds – cut, colour, clarity, and carat weight – the most important characteristics to understand when considering a diamond jewellery.

We’ll also explain how to understand and apply the 4Cs to smaller stones and pieces of jewellery, not only to a larger solitaire stone!

Cut

The most important of the 4Cs is cut as it has the greatest influence on a diamond’s sparkle. Without a high cut grade even a diamond of high quality can appear dull and lifeless. A diamond cut poorly and too deep can face-up smaller than it actually is.

At JIRE, we stock diamonds with high cut quality. You can tell we do this by seeing how all our jewellery sparkles perfectly.

Colour

The next important factor is colour, which actually refers to a diamond’s lack of colour. The highest quality diamonds are colourless, while those of lower quality have noticeable colour, which shows as pale yellow, grey or brown in diamonds. The Gemmological Institute of America (GIA) grades diamond colour on a scale of D (colourless) to Z (light yellow or brown). However most diamonds, including H colour and Gcolour, have varying amounts of colour.

At JIRE, we stock D-H coloured stones. Whilst most of our jewellery is set with F-G coloured stones, we stock a good range to give our customers plenty of options to choose from.

Clarity

Often the importance of Clarity in the 4Cs is overlooked because the tiny imperfections are often microscopic. The surface flaws are called blemishes, and internal defects are known as inclusions.  The different types of imperfections can affect the diamonds sparkle so are important to consider.

At JIRE, we stock diamonds with SI grading or above. Most of our jewellery is set with VS-SI stones we have plenty of options to ensure value for money, depending on the individual piece of jewellery.

Carat

The term carat actually refers to the diamond’s total weight and not its size.

A metric “carat” is defined as 200 milligrams. All else being equal, diamond price increases with carat weight, because larger diamonds are rare and desirable. But two diamonds of equal carat weight can have very different values (and prices) depending on three other factors within the 4Cs: Clarity, Colour, and Cut. It’s important to remember that a diamond’s value is determined using all of the 4Cs, not just carat weight.

At JIRE, we stock all sizes!

Two other C’s Cut (shape) and Certification are important to understand.

Shape (or cut)

Each diamond shape has different attributes that affect price and quality grade.

At JIRE, we stock all shapes! Simply browse our web shop.

Certification

Unbiased diamond grading reports are key when considering larger stones.
