Engagement rings, wedding bands and one of a kind pieces, drawn with you by our G.I.A. certified gemologist and made on site at our Clybourn showroom.
Most rough diamonds grow as octahedra, eight faces in the shape of two pyramids joined at the base.
Before any cutting, the cutter maps the best stone that fits inside the crystal.
The top is sawn off to make the table, and the girdle is ground round.
Blocking places the first 17 facets.
Brillianteering adds 40 more, for 57 in all.
Each facet is polished on a wheel coated with diamond dust, and the stone starts to show fire.
The setting is modeled in jeweler’s wax.
The wax is burned out of a plaster mold and replaced with molten platinum.
The stone is set and the prongs are closed over it.
Designed with you and made in house at 1739 N. Clybourn.

Five steps, from a phone call to a finished ring. Making it usually takes about two weeks once you approve the design.
01
A short call about what you are picturing, the metal and colors you like, and the budget. Engagement rings, cocktail rings, bracelets, necklaces, earrings and pendants are all on the table.
02
We start with the stones in our own stock and search dealers worldwide when we need to. Every candidate comes to the showroom, so you choose with the stone in front of you.

03
The longest step. Viktor is an artist as well as a jeweler, and he sketches with you until every idea you brought has a place on the page.

04
The approved sketch is rebuilt as an exact 3D model, so you can turn the ring and check every angle to the millimeter before any metal is involved.

05
When the model is approved, we make the piece in house. Expect about two weeks.
