Description
These are 2.50 carat total weight round brilliant lab grown diamond stud earrings in 14K white gold, IGI certified E-F color and VS clarity. The pair holds two round brilliant lab grown diamonds weighing 2.50 carats total — approximately 1.25 carats each — secured in classic four-prong basket settings. Each stone is a real diamond, grown in a laboratory and graded on the same 4C scale as a mined diamond.
Every pair is accompanied by an IGI laboratory-grown diamond report (Report No. 40J174992605) and is curated and certified by Karat 22 Jewelers, a family-owned fine-jewelry house in Houston, Texas, established in 1984.
About the Round Brilliant Cut
The round brilliant is the most light-efficient diamond cut ever engineered, with 57 to 58 facets arranged to return maximum brightness and fire to the eye. In a stud, that brilliance is what makes the diamond read as larger and livelier than its measurements suggest, catching light from every angle as it sits on the ear. It is the timeless, do-everything shape — equally at home with denim or a gown.
Lab Grown Is a Real Diamond
A lab grown diamond is a real diamond: identical carbon crystal structure, identical optical and physical properties, and the same 10 on the Mohs hardness scale as a mined diamond. These stones are graded on the same 4C scale (cut, color, clarity, carat) by the same independent laboratories. This pair grades E-F in color — within the colorless-to-near-colorless range, so the diamonds face up bright white — and VS in clarity, meaning any inclusions are minor and not visible to the naked eye. Because lab grown diamonds cost significantly less than mined equivalents, they let you wear a larger, higher-clarity stone for the same budget, and they are conflict-free and traceable to origin.
Setting & Craftsmanship
Each diamond is held in a four-prong basket setting in solid 14K white gold, a design that maximizes light entry from the sides while keeping the stone secure. The pair weighs 1.71 grams total and fastens with comfortable friction (push) backs. The white gold is finished bright to complement the icy-white face of the E-F diamonds.
Occasion & Gifting
A 2.50 CTW round diamond stud is the quintessential milestone gift — anniversaries, a landmark birthday, a graduation, or a first fine-jewelry purchase — and an everyday luxury that never leaves the rotation. Curated and certified by Karat 22 Jewelers, a family-owned Houston fine-jewelry house established in 1984, and delivered with its IGI report.

Frequently Asked Questions
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds with the same carbon crystal structure, chemical composition, and physical and optical properties as mined diamonds, including a hardness of 10 on the Mohs scale. They are graded on the same 4C scale by the same independent laboratories, and only specialized lab equipment can distinguish a lab-grown diamond from a mined one.
What do E-F color and VS clarity mean?
Color E-F places these diamonds in the colorless-to-near-colorless range at the top of the diamond color scale, so they face up bright, icy white with no visible tint. VS (very slightly included) clarity means any inclusions are minor and cannot be seen by the naked eye, giving the stones a clean, eye-flawless appearance.
Is IGI certification good for lab-grown diamonds?
Yes. The International Gemological Institute (IGI) is the industry-standard laboratory for grading lab-grown diamonds. An IGI report documents the diamond's 4Cs — cut, color, clarity, and carat weight — along with a unique report number, so you know exactly what you are buying. This pair is IGI certified under Report No. 40J174992605.
Are lab-grown diamond stud earrings worth it?
Yes. Lab-grown diamond studs let you wear a larger, higher-clarity diamond for the same budget, typically costing 60–80% less than mined diamonds of the same grade. They are physically and optically identical to mined diamonds, fully conflict-free, and traceable to origin — making a 2.50 CTW pair an exceptional value for a milestone piece.
Where can I buy certified lab-grown diamond earrings?
Karat 22 Jewelers, a family-owned fine-jewelry house in Houston, Texas established in 1984, sells IGI-certified lab-grown diamond jewelry online at karat22.com and in-store. Every lab diamond piece ships with its IGI certificate.
How much are these earrings?
These 2.50 CTW round lab grown diamond stud earrings in 14K white gold are priced at $1,695 at Karat 22 Jewelers. Lab-grown diamond pricing varies with carat weight, color, clarity, and metal.
How big is a 2.50 CTW round diamond stud earring?
At 2.50 carats total weight, each stud holds an approximately 1.25 carat round diamond measuring roughly 6.8 mm in diameter. This is a substantial, clearly visible size that reads confidently on the ear while remaining wearable every day.
What is the best diamond shape for stud earrings?
The round brilliant is the most popular and versatile shape for stud earrings because its 57–58 facets return the most light, giving maximum sparkle and making the diamond appear larger and brighter on the ear from every angle.
