Custom cut

Nothing about this one has been decided.

Every stone on this site was a decision someone made about a piece of rough. Table size, crown height, where the culet sits, how much weight to spend getting the outline true. On a custom cut those decisions are yours, and you see them before anything touches a wheel.

Bring a sketch, a reference photograph, or a shape that does not exist yet. We will tell you plainly whether it can be cut, what it will cost, and what it will cost in weight to cut it properly.

Plotting the cut
The process

Five steps. You approve the fourth one.

01 Concept

Send an idea, a sketch, or images of a stone you want made. We look at it against the rough we can get and tell you whether it is cuttable as drawn, or what has to change for it to work.

02 Plotting

The shape is plotted in three dimensions against real rough. This is where proportion is decided: outline, table, crown height, pavilion depth, facet arrangement, culet. We plan the cut first and let the carat land where it lands.

03 Approval

You see the plot rendered before production. Adjustments to outline, proportion or facet arrangement happen here, on screen, where they cost nothing. Once it is signed off the order is invoiced and goes into the run.

04 Cutting

Cut in our own factory in Surat by the same hands that cut our natural goods. Laser sawing, faceting, hand finishing. The LITHOS bull is laser inscribed on the girdle.

05 Delivery

Six weeks from approval uncertified. Eight weeks with a full IGI grading report. Every stone is inspected against the approved plot before it leaves the workshop.

What we cut to order

Shapes the market does not carry.

Most of what a jeweler can source, their competitors sourced from the same three places. A cut made to your spec is the one thing on the bench that nobody else can quote against.

Historic makes

Old mine, old European, rose, step and antique cuts, cut to historic proportion rather than to a modern yield target.

Geometry

Hexagon, octagon, kite, lozenge, shield, carre, half moon, and outlines that do not have a name yet.

Pairs and suites

Matched from the same batch rather than assembled from inventory. The part most of the trade cannot do at all.

Color

Colorless through champagne, including rough grown warm and left untreated. Salt and pepper on request.

Certification

IGI on request. Uncertified runs six weeks, certified runs eight. The difference is grading time, not cutting time.

Trade terms

Approved trade accounts see trade pricing on custom work, with memo available on request.

Start here

Tell us the shape. We will tell you if it cuts.

A sketch on a napkin is enough to start. Send it with a target size and a rough idea of the color you want, and we will come back with what the rough allows, what it costs, and how long it takes.
