How can I be assured that the diamond I've ordered is the one I'll receive?

All of our diamonds come with full certification that includes details of the identifying characteristics and proportions of your individual diamond.In addition to this, most of our diamonds are laser inscribed for extra security. We check each diamond against its certificate before sending it to the customer, using the certificate number on the girdle which can be seen when using 20x magnification.

Can I collect my purchase in person?

Yes, absolutely. You can arrange to collect your purchase from our Sydney office during business hours.

Do you have a showroom?

Yes, our Sydney showroom is open during business hours by appointment only, should you wish to see a selection of our jewellery and meet our fully trained sales professionals.

Why do diamond prices differ from one day to the next?

Diamond prices fluctuate according to the value of the US dollar as diamonds are traded around the world in US dollars. All prices quoted on the Diamond Emporium website are valid for 24 hours and are updated daily at 12.00 am.

Why are your prices so low?

For a number of reasons; we buy direct from the supply factories and in large quantities meaning we pay less so that we can pass these savings on to our customers. Because we buy from high up the supply chain we do not have to pay additional mark ups or margins from third parties along the way.

We also have partnerships with the largest diamond cutters and manufacturers around the world which gives us a high level of buying power. Lastly, as we trade almost entirely through our website we incur lower overheads than a retail chain as well as being able to hold a larger inventory. Both of these mean we can offer more competitive pricing.

Do you provide a warranty on your products?

We offer a lifetime warranty as well an upgrade service, details of which can be seen on our policy page. Life Time Warranty and Upgrades

What is your return policy?

To secure diamonds on your behalf Diamond Emporium requires a 50% deposit of the diamond cost.

In the rare event that you are not satisfied with the diamond, the deposit you have paid is fully refundable.

Once the diamond is viewed in our offices and you are satisfied with it, we would appreciate the remainder of the diamond cost to be paid within 3 days.

During this 3 day period after you have viewed your diamond, you have the opportunity to exchange or receive a full refund for your diamond purchase.

How much will GST, shipping, insurance and delivery charges cost?

All of these are included in the price of your diamond, except for GST which will be added separately. Delivery outside of Australia will be charged separately too, to cover the additional cost that this incurs.

How will my purchase be packaged?

You will receive a box with either a presentation box inside for diamonds only, or a ring box inside if you have purchased a ring. The box will be tied with a Diamond Emporium embossed ribbon and placed in a gift bag. The invoice and original diamond certificate are also included.

Is there a cost involved if I return my diamond/ring without the certificate?

Yes, before we can accept the return the diamond would have to be re-certified and inscribed by an independent laboratory which costs $350, for which you will be responsible. In addition to this, the cost of posting or couriering the diamond back to us is your responsibility. Please note that unless we know that the diamond certificate issued with your purchase has been destroyed we will regard the possibility of a diamond certificate falling into the wrong hands as a serious issue.

What is the difference between a certified and uncertified diamond?

A certified diamond has been subjected to a thorough grading process by an independent, accredited laboratory who then supplies the diamond with a certificate. This certificate contains information on the individual characteristics of the diamond that allow a gemologist to to identify it upon inspection and set it apart from other diamonds. If the unique certificate number is inscribed on the diamond, it's identity can easily be verified using a strong microscope. An uncertified diamond is one that has not been through this process and therefore does not have it's own unique certificate.

What is diamond colour and clarity enhancing?

This is a process by which a diamond has undergone an unnatural process to enhance it's colour or clarity. This is done either by heat treatment to make the diamond whiter or by drilling into a dark inclusion then vaporising it with a laser or chemical agent to get rid of it, then filling the hole with clear resin. Customers should always be aware if these kinds of treatments have been undertaken. Diamond Emporium does not trade with these stones as their quality and value has been compromised and they are below our standards.

What is fluorescence?

When diamonds reflect a blue/yellow/green light under an ultraviolet light they are said to be luminescent of fluorescence. This is a rare phenomenon and should be highly valued. However, many members of the diamond trade see it as a negative trait but in fact fluorescence can make diamonds look better in overall colour and appearance. Diamonds with fluorescence offer good value to the customer.

Which metal is best?

Our ring collection as well as the majority of our fine jewellery comes in platinum, white gold or yellow gold. Platinum is more durable and shows fewer scratches and has a bright, modern look as does white gold. Yellow gold has a warmer hue and chic appeal.

What is the difference between white gold and platinum?

A common misconception is that white gold and platinum are the same things and only separated by price but this is not the case. Platinum is four times stronger than white gold, does not discolour or oxidise as white gold does and is more durable. In terms of appearance, platinum has a very white and slightly duller appearance than white gold, which shines brighter. 18 karat white gold is a very good option for a customer who is looking for a purer metal at a reasonable price.

What is rhodium?

Rhodium is a metal alloy that is formed when platinum is separated and is applied to fine jewellery to create an incredibly hard protective coating on silver and gold. Rhodium also provides a white shiner and tarnish prevention.

How do I work out my ring size?

We have a printable ring sizer for you to find your ring size, we can also send you a complimentary plastic ring sizer upon request. Alternatively, you can come into our Sydney showroom for us to measure your ring size.

What is laser inscription?

Laser inscribed diamonds have their unique serial number inscribed on their girdle to allow identity verification in case of theft or after cleaning or repair. The laser inscribed serial number can only be seen under high magnification.

What is a DE Ideal Cut?
A DE Ideal Cut diamond excels all criterion necessary for it to be classed as 'Excellent'. These diamonds produce the greatest brilliance and fire. For more information please refer to our Diamond Grading information.
What is a diamond's make?

A diamond's 'make' refers to it's cut, finish and overall appearance. At Diamond Emporium we evaluate each diamond on a 'make' scale that takes into consideration it's proportions as well as brilliance and fire.

Are some diamond certifications better than others?

Yes, these come from the world renowned and most highly respected laboratories, the GIA, AGS and HRD. However, all of the certifications that Diamond Emporium carries are from one of the four universally trusted gemology labs. To learn about the different labs and the advantages of each, please visit Diamond Certification.
