The Florence Round Cut Sapphire Stud Earrings deliver understated luxury through expert design. Each lab-grown sapphire is cut to Ideal Cut standards for maximum brilliance, then secured in a three-prong martini setting that creates a sleek, low-profile silhouette sitting close to the earlobe. Available in 14K or 18K solid gold (white, yellow, or rose) or PT950 Platinum.

Handcrafted in New York by Ring Premier's master jewelers, the Florence's three-prong martini design allows more of the diamond to be exposed to light, enhancing perceived size and fire. Three prongs taper downward into a narrow, inverted-cone gallery — the shape that gives the martini mount its name. The tapered design seats the diamond lower and closer to the earlobe than a standard basket, reducing the profile height. With three claws instead of four, approximately 25% less metal obscures the diamond's crown facets, increasing the visible face-up area of the stone. The result is a diamond that appears slightly larger and shows more fire and scintillation from the face-up viewing angle.

0.50 CTW 4.0 mm each
1.00 CTW 5.15 mm each
1.50 CTW 5.75 mm each
2.00 CTW 6.40 mm each
3.00 CTW 7.40 mm each
4.00 CTW 8.20 mm each
5.00 CTW 8.75 mm each

Measurements are approximate. Actual dimensions may vary slightly based on cut proportions.

Every pair of Florence 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 Florence round diamond studs Ideal Cut?

Yes. Every round brilliant diamond in the Florence 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 Florence lab sapphire 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 sapphires the same as mined sapphires?

Lab-grown sapphires are chemically, physically, and optically identical to mined sapphires. 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 Florence studs?

The Florence 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 martini mount and how does it differ from a four-prong basket?

The Florence studs use a three-prong martini mount — named for the inverted-cone shape of its gallery, which resembles a martini glass. Three claws secure the diamond at the crown while the tapered gallery seats the stone lower and closer to the earlobe than a traditional four-prong basket, reducing the overall profile height. With one fewer prong, approximately 25% less metal covers the crown facets, which increases the visible face-up area and allows more light to enter the stone. Jewelers recommend the martini mount for wearers who prefer a modern, low-profile aesthetic and want maximum face-up brilliance from a smaller number of prongs.

How should I care for my Florence earrings?

Clean your Florence 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.

Absolutely stunning. I was not disappointed! The quality is as described.
I waited a bit longer then expected but if due to checking and getting it perfect, then it was worth it.
The one thing I would suggest to customers when deciding on the setting is that with a larger stone the martini setting will droop a little.
I debated exchanging them for the 4 prong setting but remembered I had gold, David Yurman backings and they hold the earring up with no drooping.
