Terms for our first collaboration
Minimum purchase: €500 excluding tax in stones after discount, excluding certificates and shipping. You may combine several references. Melee lots start at 1 ct per reference; centre stones are sold as whole stones according to the selected reference.

Select references and quantities in carats. The calculator details stones, the indicative discount and IGI options. Shipping is quoted separately in the final offer.
Independent verification
IGI option per lot: the quote specifies the stones covered, the document and how it is supplied. Available reports can be checked at igi.org. The quote specifies which stones the report covers.
