Portuguese cut
The most facets we cut: tier upon tier of them.
A Portuguese cut carries several extra rows of facets above and below the girdle, producing a dense, kaleidoscopic pattern rather than the clean arms of a round brilliant. It is a showpiece, and it wants size and light to be understood.

We move enough volume that we will not pretend to know which stone in the parcel becomes yours. What we will do is put a floor under every part of it and let the variance run in your favor — the weight, the clarity and the color can come in above what you paid for, and regularly do.
For example
You order 1.00 ct · VS1 · F.
You might receive 1.10 ct · VVS1 · D.
Same price either way.
What VS1 and D–F actually mean
- VS1
- Very slightly included. Minor inclusions, hard to locate even under a loupe.
- Color D
- Absolutely colorless. The top of the scale, and mostly bought for that fact.
- Color E
- Colorless. Distinguishable from D only by a grader with comparison stones.
- Color F
- Colorless. The last grade before faint warmth appears under laboratory light.

Buying a portuguese
A Portuguese cut carries several extra rows of facets above and below the girdle, producing a dense, kaleidoscopic pattern rather than the clean arms of a round brilliant. It is a showpiece, and it wants size and light to be understood.
Proportion to expect: 1.00. We cut to the middle of that range, so a portuguese from us looks like the shape you pictured rather than a stretched version of it.
Every portuguese is laboratory grown, graded by IGI or GIA, and shipped with its report. If the stone that arrives is not the one you want, request a return authorization within 30 days.
