All of our diamonds above 0.3 carat come with a diamond report from an independent diamond grading laboratory. This way you can be very sure you are getting the high quality diamond that we promised.
We hope you find this guide to buying Designer Engagement Rings helpful but if you have any questions please don't hesitate to contact us.
These are some of the main points that are outlined in the diamond certificate:
An independent diamond grading certificate is produced by a diamond grading laboratory which is completely independent of any distributor or retailer.
It is very important that you purchase your Diamond Engagement Ring with an independent diamond certificate. Some jewellers may offer their own diamond certificate. If this is offered you have no real way to know if the diamond they are selling you is exactly as they describe it. If its their own diamond certificate that is not independently certified they can put what they want on it. Be very aware of this as they are looking to make money so their certificate may not be 100% accurate!
1791 Diamonds New Zealand only sells diamonds with independent diamond certificates from recognised diamond grading laboratories.
1791 Diamonds New Zealand only sells diamonds with completely independent diamond grading certificates so you have 100% proof of the diamond quality in your engagement ring.
Independent laboratories only examine and grade diamonds, they do not sell them. Therefore they will not make any diamond a better grade than it actually is, their reputation depends on it.
This is a once in a lifetime purchase and we feel this assurance of quality is essential for anyone purchasing a Designer Engagement Ring.
The diamond in your engagement ring will have been graded by one of the following laboratories:
For further information see our Design Philosophy and Diamond Policy.
Diamond grading laboratories use advanced laboratory equipment to accurately measure the weight, dimensions, symmetry, and cut of your diamond. Based on the measurements and the angles a mathematical equation will be applied to provide the cut grade for your diamond. This equipment includes computers and sophisticated specialised diamond machines such as DiamondView and DiamondSure which are also used to detect fake stones.
Note that fake stones such as cubic zirconium become chipped and damaged within weeks which is why they are not a good substitute, you simply cannot beat the durability and beauty of a real high quality diamond!
Diamond grading, in terms of colour and clarity, is largely down to human judgement; so when grading a diamond, the laboratories will invest teams of at least 2 diamond graders to separately analyse your diamond. They need to agree on the colour and clarity of your diamond for your report.
In order to write your diamond report / certificate, your diamond will be:

If you are looking to have your Designer Engagement Ring insured (highly recommended!) you must first take your ring for a valuation.
The valuer will value the Engagement Ring based on the likely replacement cost of the diamond/s and the precious metals, the craftsmanship required to create the ring is also taken into account.
