The Geneva Round Cut Ruby Stud Earrings are a foundational piece in any fine jewelry collection. Each lab-grown ruby is precision-cut to Ideal 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.

Measurements are approximate. Actual dimensions may vary slightly based on cut proportions.
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.
- Premium handcrafted jewelry box designed for gifting
- IGI certificate or professional appraisal (depending on carat weight — see certification details above)
- Certificate of Authenticity
- Free fully insured shipping with tracking
- 30-day free returns — no questions asked
Are the Geneva round diamond studs Ideal Cut?
Yes. Every round brilliant diamond in the Geneva collection is graded Ideal Cut, which means it has been cut to precise proportions that maximize light return, fire, and scintillation. Ideal Cut is the highest cut grade available and represents the top tier of light performance in round diamonds. This is one of the most common questions we receive, and we ensure every round stud meets this standard.
Do the Geneva lab ruby studs come with certification?
All lab-grown gemstone studs from Ring Premier include a professional appraisal and Certificate of Authenticity. The appraisal documents the stone type, carat weight, color, clarity, metal content, and estimated replacement value, and is recognized by insurance companies.
Are lab-grown rubys the same as mined rubys?
Lab-grown rubys are chemically, physically, and optically identical to mined rubys. They possess the same hardness (10 on the Mohs scale for diamonds), the same refractive index, and the same crystal structure. The only difference is their origin: lab-grown stones are created in controlled environments using either Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) technology. A jeweler cannot distinguish them from mined stones without specialized laboratory equipment.
What metal options are available for the Geneva studs?
The Geneva studs are available in seven metal options: 14K White Gold, 14K Yellow Gold, 14K Rose Gold, 18K White Gold, 18K Yellow Gold, 18K Rose Gold, and PT950 Platinum. 14K gold contains 58.3% pure gold and is more durable for everyday wear, while 18K gold contains 75% pure gold and has a richer color. White gold is rhodium-plated for a bright finish. PT950 Platinum is 95% pure platinum — the densest and most naturally white precious metal, requiring no plating and developing a distinctive patina over time. All metals are recycled.
What shipping and return policy applies?
Ring Premier offers free fully insured shipping on all orders. Every earring ships in premium handcrafted packaging. We offer 30-day free returns. Professional care services — including ultrasonic cleaning, rhodium re-plating, and prong retipping — are available.
What is a four-prong basket setting and why is it the most popular?
The Geneva studs use a four-prong basket mount — the most widely used setting in diamond stud earrings worldwide. Four individual prongs grip the diamond at the crown (the upper portion of the stone above the girdle), leaving the table and pavilion facets fully exposed. The open gallery basket underneath allows light to enter through the pavilion, which is essential for the stone's brilliance (white light return) and fire (the rainbow flashes caused by spectral dispersion). This setting offers the best balance of stone security and optical performance — it's the industry standard for a reason.
How should I care for my Geneva earrings?
Clean your Geneva earrings at home by soaking them in warm water with a drop of mild dish soap for 15–20 minutes, then gently brushing with a soft-bristle toothbrush around the prongs, gallery, and pavilion. Rinse under warm running water and pat dry with a lint-free cloth. Avoid exposing your earrings to harsh chemicals, chlorine, or abrasive cleaners. Store them separately in the provided jewelry box to prevent scratching. Ring Premier offers professional cleaning, rhodium re-plating, and prong retipping services. Professional care services are available.
