The emerald cut is the most demanding shape to grade — its long step facets act as a magnifying glass for clarity. A small inclusion that would be invisible in a brilliant cut becomes obvious in an emerald cut, which is why every diamond in this collection carries a full GIA report documenting clarity, color, polish, and symmetry stone by stone.

Emerald cuts photograph differently than they look in person — the elongated proportions read more dramatic on the hand than the spec sheet suggests. The geometry rewards center stones with high color (D-G) and clean clarity (Flawless to VS2); below VS2, the eye begins to catch what the cut reveals.

Three-stone settings dominate this collection because the architecture flatters the emerald cut’s lateral lines — tapered baguettes or trapezoid sides extend the silhouette without competing for attention. Carat weights range from 1 carat (engagement scale) to over 25 carats (high-jewelry signatures). Every center stone is independently GIA certified, with the laser-inscribed report number verifiable on gia.edu.

Step-cut emerald diamonds graded D-G in clarity Flawless to VS2, hand-set in platinum and 18kt gold. Every center stone certified by the GIA.

Why GIA Certification Matters for Emerald Cuts

Why GIA Certification Matters for Emerald Cuts

GIA — the Gemological Institute of America — is the world’s most trusted independent diamond laboratory. A GIA report documents the four Cs (carat, color, clarity, cut) plus polish, symmetry, fluorescence, and proportions. For emerald cuts specifically, the report’s plotted clarity diagram is critical: it shows exactly where any inclusions sit, which determines whether they’re visible to the naked eye through the step-cut facets.

Diamonds without GIA grading at this carat weight are uncommon in fine jewelry and should be approached with caution. Every emerald cut in this collection is certified before it enters our atelier; the GIA report accompanies the piece at delivery.

Frequently Asked Questions

What is the best clarity for an emerald cut diamond?

VS1 or higher is recommended for emerald cuts. The step-cut facets are unforgiving — VS2 can show inclusions to the trained eye in larger sizes, and SI grades are generally not advisable above 3 carats.

How much is a GIA certified emerald cut diamond ring?

Pricing scales with the four Cs and the GIA report. A 1-carat F VS1 emerald cut starts in the low five figures; a 10-carat D Flawless emerald cut reaches the seven-figure tier. Every piece in this collection is priced on request.

Is an emerald cut diamond a good investment?

GIA-certified D-G colored emerald cuts above 5 carats with VS or better clarity have historically held value well, particularly Type IIa stones. We provide full GIA documentation and original pricing records to support resale or appraisal.

How big does an emerald cut diamond look on the hand?

Emerald cuts tend to face up larger than other shapes of the same carat weight because of their elongated proportions. A 5-carat emerald cut typically measures around 11 × 8 mm — visually equivalent to a 6-carat round brilliant.
