Ian Gallacher’s source for diamonds in Antwerp is known worldwide for the cutting and polishing of ideal cut diamonds. They have been in business now for over a century and were the first to cut diamonds to the ideal cut proportions. They became a diamond trading company sight holder in 1946 and designed the modern oval cut diamond in 1957. Perhaps one of the main reasons that we buy from this source, is that they are in direct partnership with Russia’s leading diamond mining company, for the cutting and marketing of polished diamonds.
To this day, our source for diamonds is the only firm specializing in diamond cutting, to be listed on the American stock exchange. The largest diamond that this company have cut and polished was the 726 carat Jonker diamond.
