What We Sell

Diamonds

At I. Morgenstein, we specialize in carefully calibrated parcels of natural diamond melee, from VS to I2 qualities, sourced with precision and consistency. We also offer made-to-order assortments in a range of shapes and sizes, including GIA-certified natural diamonds up to 20 carats.

Our production line features beautifully matched fancy pairs such as half moons, trilliants, kites, trapezoids (both step and brilliant cut), and shields. Each diamond layout is hand-selected and cut to achieve perfect balance, symmetry, and brilliance, tailored to your design needs.

Gemstones

We maintain a calibrated collection of fine rubies, sapphires, and emeralds — both certified and uncertified — available up to 10 carats. Alongside these, we offer a broad assortment of semi-precious gemstones in round and fancy cuts. Every stone is chosen for its color harmony, precision cut, and consistency, making them ideal for high-quality jewelry production.
