Buying Guide


Getting started… Look, but don’t rush.

Once you’ve decided that you want to begin looking seriously for a diamond or gemstone, our advice is to start doing research. If it’s going to be a surprise, try and get indicators of your partner’s jewellery style tastes and what diamond or gemstone shapes they prefer.

Once you have a better idea of what you’re trying to achieve, you can now start to do more specific research as well as getting a better idea of what you’ll need to budget for the finished piece.

Choose From The Finest Gemstones In Sydney

As trusted diamond & gemstone brokers in Sydney, we source and select only the finest stones available worldwide, which are then available for first-hand viewing & education at our Parramatta design studio & workshop.

As unbiased experts we will only let you purchase loose diamonds that are in the top 10% of light performance & visual qualities that meet your requirements to be made into bespoke handmade jewellery, such as a diamond solitaire engagement ring or diamond wedding ring.

Where To Start…

We recommend doing some gemmological research online from a range of sources (preferably unbiased sources; will be a great resource). Now while it’s impossible to become a gemstone expert overnight, a basic understanding of the type of gem you’re looking for will really help you to understand the things you should be paying for and the things you shouldn’t be paying for.

At this stage, it will be worth your while to start getting hands-on and seeing the translation & impact of graded technical detail to the physical stone. Not only will this help you to develop valuable reference points in what you like most, but just as importantly, will allow you to get the best value for money. A hard working diamond & gemstone broker will be more than happy to arrange a selection of stones to view in your search criteria, under no obligation.

Now having a better understanding of what you’re looking for, you’ll want to start researching your options for making the ring. I’m sure if you’re reading this, then you realise that you don’t simply have to buy something pre-made in a jewellery retail shop (the most expensive way to buy). Our personal belief is that an engagement ring, wedding ring, or any piece of jewellery should be unique, an extension of your personal taste & style. There’s a few different ways you can go about producing custom designed, bespoke designer jewellery and at this stage I would highly recommend sitting down with a reputable designer & handcrafting jeweller and getting some unbiased, expert advice about the best ways to create a ring.

After doing this research, you will be well informed, have a much better understanding of the best approach for you, and hopefully have found someone you trust and want to work with…

Look at many options; look for ‘WOW’ factor. If a gemstone doesn’t grab you and make you keep going back to it, then keep looking (it’s not the option for you). You don’t need to be an expert to know when you see something beautiful, particularly once you’ve developed points of reference in quality by comparing several stones at the same time.

Once you’ve found that ‘WOW’ factor gem, get into the detail. Make sure you understand each and every aspect of the gem before committing to a purchase. Put it under 10x magnification and map out the clarity characteristics, being mindful of anything that may be visible to the unaided eye as well as any external blemishes that could lead to damaging the stone in the future.

Now that you’re more familiar with your selection, it will be highly important to view it in a range of lighting conditions and sources (i.e. fluorescent, halogen, LED, natural light, sunlight.), as this can alter the face up characteristics of the gem and will ensure there are no surprises after you’ve committed to a purchase.

There are also a range of other factors to consider when purchasing your ideal gemstone, but don’t worry, as your personal broker & unbiased industry expert, we take the stress and hard work out of the equation. Get in touch with us to arrange an obligation free viewing & consultation, we would love to help you>
