What is a diamond?

A diamond is a precious stone, sourced from deep within the earth, made of a clear and colourless form of pure carbon, the hardest naturally occurring substance.

What is the most popular engagement ring?

The classic round centre solitaire on a plain band.

How should I pick a shape?

Most people are naturally predisposed to liking a certain shape of things that generally fall into two categories – round or geometric. When you are making a big investment like a diamond, you should look at the shapes of things you normally buy – watches, earrings, handbags, sunglasses – and go with that. But the most important thing about choosing a shape is to go and try rings on. You may be attracted to something on Pinterest, but when it’s on your hand, it may not suit you.

What does 1.00ctw mean?

CTW means ‘carat total weight’ and tells you the weight of the diamonds on a ring combined. One carat is one-fifth of a gram.

How much should I spend on a diamond?

You should always spend what you feel comfortable spending, by basing your budget decision around what you’ve learned about diamonds. Begin by talking to an expert about your budget and go from there and let them help you make decisions.

Should I buy a certified diamond?

This all depends on what you want. Talk to an expert about the different types of certification and they will be able to give you the best advice about what you should do.

What does GIA mean?

The GIA is the Gemmological Institute of America – the world’s largest and most respected non-profit institute dedicated to research and education in the field of gemmology and the jewellery arts. It is the creator of the 4Cs of diamond value.

What’s the difference between 18ct and 9ct gold?

The primary difference between the two is the precious metal content. 18ct gold contains 75 percent pure gold and 9ct gold contains 37.5 percent pure gold.

What is rhodium plating?

Rhodium plating is used on jewellery to help create a surface that shines and resists scratches and tarnish. It also gives white gold its ultra-white colour by providing a coating over the existing metal.

What are the Four C’s?

The Four C’s of Diamond Quality is a standard developed by the Gemological Institute of America to assess the quality of diamonds. They are: cut, colour, clarity and carat.

What does ‘near colourless’ mean?

The GIA defines diamonds graded between G and J on the diamond colour chart as ‘near colourless’.

What is millgrain?

Millgrain is a finish found on vintage settings that goes around the edges of a diamond. It serves as a frame that highlights the beauty of the diamond.

How do I find out a finger size?

There are a number of ways to do this. You can go a jeweller and have it measured, bring in another piece of jewellery she wears (you need to know what finger it fits on), or go online and do a measurement.

Can rings be resized?

Yes, but only by a certain number of sizes.

How long does it take to make a ring?

Time frames can vary, but generally, it takes between four to five weeks for a ring from the Whitakers core collection and five to six weeks for a fully customised piece.

When should I purchase my wedding ring?

You should really do this when it works for you, but don’t leave it until the last minute! If you are buying from Whitakers, you can take advantage of our lay-buy service and payment plans.

Should I insure my engagement ring?

This is personal choice. Whitakers recommend insurance from Q-Report and we can assist with your jewellery bought with us.

What is normal wear and tear?

As its name suggests, ‘normal wear and tear’ is caused through the everyday wearing of jewellery. For example, claws can get worn down, and bands can get thinner just through constant rubbing on your hand. Normal wear and tear is covered by the Whitakers Lifetime Care Plan, whereas damage caused by an ‘event’ – such as a claw snapping off because you’ve caught it on something – is not.

How do I keep my ring clean?

If you purchase your ring from Whitakers, you can have instore cleaning done whenever you like; and if you purchase our Lifetime Care Plan you can have full reconditioning done annually in our workshop at no charge. At home, just use warm, soapy water and a soft toothbrush to keep the sparkle!
