How to choose a diamond?


Tayha Designs provides you with the unique opportunity to have your jewellery custom designed and purpose made, to treasure and wear for a lifetime.


You will have a say in every step of the process and although this is fun, we understand it can also be overwhelming.


When working with customers my aim is to educate you on what you are buying, without complicating the process. Think of me as your personal shopper - I want to find you the perfect diamond that fits all your requirements and sparkles the brightest, so your jewellery continues to look amazing for all the years to come.


Gemstone sourcing single diamond

There are many different aspects that can affect diamond quality and its interaction with light, these factors are reflected in the price of the stone. When we begin discussing your design, budget is important and must be considered from the very beginning, as the centre stone will take up a large portion of the total cost of the ring.


I am able to source a wide selection of diamonds and gemstones, including coloured diamonds, Sapphire, Ruby, Emerald, Aquarmaine and any other semi-precious gemstone you desire, from trusted suppliers all over the world. To make the right decision and present you with three amazing options, we’ll need to narrow down our search parameters based on your preferences.


Here's what we look at…


Diamond Shape

Diamonds come in a variety of shapes, each with their own unique characteristics and appeal. From the classic round brilliant to the edgy princess cut, the shape of a diamond can greatly impact its beauty and style. Understanding the different diamond shapes available for jewellery can help you choose the perfect piece that suits your taste and personality.

The 4 C’s

Diamonds are graded according to characteristics known as the 4c's - Cut, Colour, Clarity and Carat


 


Cut

To me this is the most important aspect. A nicely cut diamond will play with light in the best way to make any diamond have a stunning sparkle.


A good cut is about the proportions of the different parts of the diamond to allow the light to come in through the top and be reflected back out. Even when a well-cut diamond is dirty from wear it will still sparkle.

Colour

If you are looking for a 'white' (colourless) diamond, the less colour it has, the higher its grade. Even the slightest hint of colour can make a dramatic difference in its value.

Diamonds do also come in a full rainbow range of colours with a price range to suit. If you are looking for something a little different, a coloured diamond may be something you would like to explore. Australia has produced some of the world’s most amazing colours and it is a great way to have a little piece of OZ all to yourself.

Clarity

Clarity in diamonds refers to the presence or absence of identifying characteristics, such as blemishes on the surface or inclusions within the diamond. Most are not discernible to the naked eye and require magnification to become apparent. The GIA created a diamond grading scale to help the consumer understand what makes one diamond worth more than another. The grading scale is based on rarity. Flawless is the rarest and therefore the most expensive. Included 3 is the least rare and therefore the least expensive.

Carat

This is the unit of measurement used to weigh diamonds and other precious gemstones. It is abbreviated to ct.


The value of a diamond is influenced by its carat weight. Larger diamonds of the same quality are worth more per carat due to rarity.
