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.

The 4c’s Clarity

VVS1-VVS2 (Very, very slightly included) (two grades) these inclusions are extremely difficult to detect at 10X magnification.

VS1-VS2 (Very slightly included) (two grades) these small inclusions are invisible to the naked eye and are seen with difficulty at 10X magnification.

SI1-SI2 (Slightly included) (two grades) these inclusions are visible at 10X magnification and in conventionally cut diamonds (diamonds that have been cut for weight retention rather than light output) can be seen with the naked eye.

I1-I2-I3 (Included) (3 grades) these inclusions are visible to the naked eye. We offer a limited number of I1 clarity diamonds with maximum light return.
