The Vienna Round Cut Diamond Stud Earrings are a statement of timeless luxury. Each lab-grown diamond 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 six-prong crown 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 draw on the most iconic diamond mount in jewelry history — the six-prong crown. Six individual prongs grip each diamond just below the girdle, creating a regal coronet silhouette that elevates the stone above the ear. The additional prongs distribute holding force more evenly than a four-prong mount, reducing the risk of a prong catching and bending — making the Vienna the most secure stud setting in the collection. Despite the extra metal contact, the open gallery beneath the crown allows light to enter from every direction — through the crown facets above, through the pavilion below, and through the open sides — preserving exceptional brilliance (white light return), fire (spectral dispersion), and scintillation (the flashes of light you see as the earring moves).

Each carat weight listed represents the total carat weight (CTW) of both diamonds combined. Use the guide below to estimate face-up diameter per stone — the measurement that determines how large the diamond appears when worn.

Total Carat Weight	Approximate Diameter Per Stone
0.50 CTW (0.25 ct each)	~4.1 mm
1.00 CTW (0.50 ct each)	~5.1 mm
1.50 CTW (0.75 ct each)	~5.8 mm
2.00 CTW (1.00 ct each)	~6.5 mm
3.00 CTW (1.50 ct each)	~7.4 mm
4.00 CTW (2.00 ct each)	~8.2 mm
5.00 CTW (2.50 ct each)	~8.8 mm

Measurements are approximate and may vary slightly depending on cut proportions and depth percentage. Ideal Cut diamonds are optimized for light performance rather than maximum face-up spread, so they may measure slightly smaller than shallow-cut stones of the same weight — but they will be significantly more brilliant.

Every pair of Vienna earrings is handcrafted in New York by Ring Premier's bench jewelers using traditional goldsmithing techniques refined for modern precision. Each six-prong crown is cast from solid gold or platinum, then hand-finished — every prong is individually shaped, tipped, and burnished to create a seamless coronet that grips the diamond securely without obscuring its brilliance. The open gallery beneath the crown is engineered to maximize airflow and light entry from all angles.

White gold settings receive a rhodium plating bath for a bright, reflective finish that complements the diamond's white light return. Yellow and rose gold settings are hand-polished to a mirror finish that warms the diamond's fire. Platinum settings are naturally hypoallergenic and develop a distinguished patina over time that many collectors prefer.

About Lab-Grown Stones

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — composed of pure crystallized carbon with the same hardness (10 on the Mohs scale), refractive index, and thermal conductivity. The only difference is origin: lab-grown diamonds are created in controlled environments using Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) methods, rather than extracted from the earth. Every Ring Premier lab-grown diamond is independently graded by IGI (International Gemological Institute) using the same 4C criteria applied to mined stones.

Are Vienna lab-grown diamond studs real diamonds?

Yes. Lab-grown diamonds are real diamonds — identical in chemical composition (pure carbon), crystal structure, hardness (10 on the Mohs scale), and optical properties to mined diamonds. The only difference is origin. Every Vienna stud diamond is independently graded by IGI using the same standards applied to mined stones.

What does Ideal Cut mean?

Ideal Cut is the highest cut grade a round brilliant diamond can receive. It means the diamond's proportions — table percentage, crown angle, pavilion depth, and girdle thickness — are calibrated to maximize light return. An Ideal Cut diamond returns more brilliance (white light), fire (spectral dispersion), and scintillation (sparkle in motion) than any other cut grade. All Vienna round diamonds are Ideal Cut.

Why six prongs instead of four?

A six-prong crown setting distributes holding force more evenly around the diamond's girdle, reducing stress on any single point. This makes the setting more secure — particularly important for active wearers or larger stones. The six prongs also create a classic coronet silhouette that gives the diamond a regal, elevated appearance. The trade-off is slightly more metal visible from the top — but with an open gallery design, light performance remains excellent.

How do I choose between Vienna (6-prong), Geneva (4-prong), and Florence (3-prong)?

Choose Vienna if security and classic elegance are your priorities — the six prongs hold the diamond firmly and create an iconic crown look. Choose Geneva if you want the most popular balance of security and light exposure — four prongs leave more of the diamond visible. Choose Florence if you prefer a minimalist, modern aesthetic — the three-prong martini mount uses the least metal for maximum stone visibility.

Do you offer IGI certification?

Yes. Every Vienna round diamond stud 1.00 CTW and above includes an IGI (International Gemological Institute) grading report documenting the 4Cs — cut, color, clarity, and carat weight. The 0.50 CTW option includes a professional appraisal documenting the stone specifications.

What closure options are available?

Vienna studs are available with three closure types: push-back (butterfly clutch) for easy on/off, screw-back for maximum security, and guardian-back (La Pousette) which combines the ease of a push-back with the security of a locking mechanism. Select your preferred closure at checkout.

Can I return or exchange my Vienna studs?

We offer 30-day free returns. Professional care services — including ultrasonic cleaning, rhodium re-plating, and prong retipping — are available. Contact concierge@ringpremier.com for any questions.
