Cut-To-Measure Fancy Shape Diamonds

Engineering Diamonds to Match Designs

Sometimes a design calls for a diamond that does not exist yet. For those projects, Excellent Facets cuts each stone to the maison’s exact specification, working from your CAD files or technical drawings to tolerances as fine as +0.00 mm / -0.02 mm, so the finished stone sits perfectly in even the most intricate setting, whether pavé, a watch dial, or high jewellery.

Because every cut is recorded digitally, the same stone can be reordered years later and made again exactly, from first prototype to ongoing production.

Our Process Guarantees

We design, not just execute

Working from a maison’s brief or sketches, our team can propose and refine optimized diamond designs collaboratively, shaping their proportions and the way they catch light before production ever begins.

Motif-Based Custom Cuts

A signature can become a stone. We work from a maison’s own motifs, translating a house symbol into a diamond cut to hold and return light beautifully, with its proportions and facets shaped for the strongest possible brilliance.

Matched Cutting

Precision across table size, facet orientation, and dimensions.

Exact Reorder Consistency

Digital calibration files ensure repeatable results across future replenishment.

Confidential, In-House Production

All drawings remain secured and are cut in our Jaipur atelier, which is currently undergoing Responsible Jewellery Council certification.

IP-Safe Environment

Controlled access, anonymized and coded client identities, and rigorous documentation protect every project.

Quality Control

Every stone is microscope-inspected and verified on the Lexus Helium scanner, and screened using five in-house technologies to ensure our 100% natural, synthetic-free promise.

The Excellent Facets Standard: Matched cutting: dimensions, table size, and facet angles. Cut tolerances: as tight as +0.00 mm / -0.02 mm. Precision checked: dimensions verified on the Lexus Helium scanner. IP security: controlled access to drawings, with client identities anonymized and coded.

We provide meticulous fluting and bagging services to ensure that our customers do not purchase any unwanted diameters or extra diamonds.

100% Synthetic Free, Zero Tolerance Technology

Our customers trust us to ensure our pipeline stays 100% free of lab-grown diamonds. To guarantee this, we invest in the latest technologies to detect synthetic and treated diamonds. Upon arrival, all diamonds in incoming shipments undergo a proprietary process curated in-house using the following machines:

De Beers AMS2™

De Beers DiamondSure™

GIA DiamondCheck™

GIA iD100™

OGI DiaTrue CXL2

We have a zero-tolerance policy for synthetics and do not allow any synthetic stones into our facilities. Additionally, we have no business interests or affiliated entities that deal in synthetic diamonds.
