These days there is a lot of emphasis put on the diamond report that usually accompanies a diamond. There are a large number of diamond grading laboratories operating around the world. Many are country specific diamond grading labs such as www.gemlab.co.nz in New Zealand or international laboratories operating in the major diamond trading centers around the world. The major international labs include the Gemolgical Institute of America - GIA, the Diamond High Council – HRD in Antwerp and the International Gemological Instute – IGI which is actually the largest diamond grading laboratory in the world.
Diamonds listed by www.diamonds.co.nz above 0.50ct come with one of the above diamond grading reports. We purchase our diamonds from new production and then get them graded at these laboratories. Many diamond merchants and online diamond jewellery retailers promote for sale diamonds already with a diamond grading report. Therefore, we have our opinions on the grade of the diamond and if we do not agree with an international diamond grading report we will state our grading on our listing.
Our advice to consumers is to get an independent diamond grading report from a local diamond laboratory before purchasing any diamond with an international diamond grading report. This will give you piece of mind that you have verified that the diamond is the diamond that should be accompanying the report.
At the end of the day you are buying a diamond and not paper, so you should always pay a lot more attention to the diamond and not the diamond grading report as this can be verified locally. This is why you should always view a diamond first before purchasing and not buy a diamond that you cannot view personally.
