At K. Rosengart we pride ourselves on selling only 100% natural diamond melee. With the M-Screen 4.0 and the Sherlock Holmes testers, we can assure our clients they are only purchasing 100% natural diamonds.

The M-Screen 4.0 is a sophisticated, high-tech screening device developed especially for large amounts of diamond melee. It automatically feeds, screens, and sorts round brilliant diamonds at a super speed of 3 diamonds per second(up to 15,000 per hour). The technology behind the screening is highly secure, accurately separating natural diamonds from simulated and potential laboratory-grown diamonds.

The Sherlock Holmes detector does it all! The Sherlock Holmes is designed to separate
all sizes of loose and mounted natural diamonds from synthetic diamonds in the D-K color
range. It also separates loose CZ, moissanite, synthetic diamond coated CZ.
