At James Oppedisano Jewellery we offer a few guarantee’s covering every single diamond we use in our jewellery, to give you assurance that every purchase of diamonds or jewellery containing diamonds you make is not supporting unethical trade but instead are providing funds to an organization who are actively preventing such activites, known as the Kimberley Process.

We guarantee that NONE of our diamonds, period, are conflict/blood diamonds and are only sourced through partners of the Kimberley Process.

We use only the highest grade of diamonds available in all our jewellery which are E-G+, VS+. The only exception to this are centre stones for engagement rings and in occasion centre stones for our high jewellery range, where we prefer to offer you all grades from all companies (including GIA certificates) so we can help you achieve the best choice for your budget and needs.
