Geneva Classic Sapphire Gemstone Oval Cut Studs

The Geneva Oval Cut Sapphire Stud Earrings are a foundational piece in any fine jewelry collection. Each lab-grown sapphire is precision-cut to Excellent Cut standards — the highest cut grade — meaning every facet is calibrated to return the maximum amount of light to the eye. The stones are set in a four-prong basket setting crafted from your choice of 14K or 18K solid gold (white, yellow, or rose) or PT950 Platinum.

Handcrafted in New York by Ring Premier's skilled jewelers, these studs combine traditional goldsmithing technique with modern precision. Four individual prongs grip each diamond at the crown, leaving the table fully open and the pavilion exposed through an open gallery basket. Light enters from every direction — through the crown facets above, through the pavilion below, and through the open sides — maximizing brilliance (white light return), fire (spectral dispersion), and scintillation (the flashes of light you see as the earring moves). The four-prong basket is the most popular diamond stud mount in fine jewelry for its ideal balance of stone security and light performance.

Every pair of Geneva earrings is handcrafted in New York by Ring Premier's skilled jewelers who combine modern precision tools with traditional hand-finishing techniques. Ring Premier exclusively uses recycled precious metals and conflict-free, lab-grown stones. All lab-grown diamonds are verified as 100% carbon neutral by Clear Neutral, a trusted third-party carbon neutrality certifier.

Each earring undergoes multi-stage quality inspection — including prong tightness testing, girdle alignment verification, and a final loupe inspection under 10× magnification for brilliance and symmetry — before shipping.

About Lab-Grown Stones

Lab-grown diamonds and gemstones are chemically, physically, and optically identical to their mined counterparts. They have the same crystal structure, the same hardness (10 on the Mohs scale for diamonds), and the same refractive index. The only difference is their origin: lab-grown stones are created in controlled environments using Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) technology. They carry no mining footprint, are certified conflict-free, and are available at a significantly more accessible price point — without any compromise in beauty or durability.
