Description
These are round brilliant lab grown diamond stud earrings with a total weight of 1.16 carats — two matched diamonds of approximately 0.58 carat each — set in 14K white gold with a classic 3-prong martini setting. Each diamond is graded E-F in color and VS in clarity, and the pair is IGI certified (Report No. 40J174922605).
Lab grown diamonds are real diamonds, identical to mined diamonds in chemistry, structure, and brilliance. This pair is backed by Karat 22 Jewelers of Houston, Texas, a family-owned fine-jewelry house established in 1984.
About These Lab Grown Diamond Studs
The round brilliant cut is the most enduring choice for a diamond stud — its 57 to 58 facets are engineered to return the maximum amount of light, so the stone reads bright and lively against the ear from every angle. At 1.16 carats total, each diamond measures roughly 5.3 mm across, a refined, everyday size that sits comfortably on the lobe and pairs as easily with a white shirt as with an evening look.
A lab grown diamond is a real diamond. It shares the identical carbon crystal structure, the same 10 on the Mohs hardness scale, and the same optical fire as a mined diamond, and it is graded on the same 4C scale by the same laboratories. The only meaningful difference is origin: these stones are grown, not mined, which makes them conflict-free and fully traceable, and delivers a larger, higher-clarity diamond for the price. Both diamonds in this pair are graded E-F color (colorless to near-colorless, with no visible tint) and VS clarity (very slightly included, eye-clean to the naked eye).
Each diamond is held in a 3-prong martini setting in 14K white gold. The martini design keeps the metal low and open, so light enters the stone from the sides as well as the top and the diamond appears to float. The posts secure with push-back friction closures, and the pair weighs 1.12 grams in total. IGI report number 40J174922605 documents the grading; the design is Karat 22 style CER04317.
A pair of certified diamond studs is the most versatile piece in fine jewelry — equally at home as a first diamond gift, an anniversary or birthday marker, a bridal accent, or a self-purchase that earns its place daily. Curated and certified by Karat 22 Jewelers, a family-owned Houston fine-jewelry house established in 1984.

Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are real diamonds with the identical chemical composition, crystal structure, and physical properties as mined diamonds, including a hardness of 10 on the Mohs scale. They are graded by the same laboratories on the same 4C scale (cut, color, clarity, carat). Only specialized laboratory equipment can distinguish a lab grown diamond from a mined one; to the eye they are the same.
What do E-F color and VS clarity mean?
E-F is a colorless to near-colorless grade at the top of the diamond color scale, meaning the diamonds show no visible tint and face up bright white. VS (very slightly included) means any inclusions are minor and not visible to the naked eye, so the diamonds are eye-clean. Together, E-F/VS is a high-quality combination that delivers a white, clean-looking diamond.
Is IGI certification good for lab grown diamonds?
Yes. The International Gemological Institute (IGI) is the leading independent laboratory for grading lab grown diamonds. An IGI report documents the diamond's 4Cs and carries a unique report number for verification. This pair is IGI certified under Report No. 40J174922605.
Are lab grown diamond stud earrings worth it?
Yes. Lab grown diamond studs give you a larger, higher-clarity diamond for your budget, typically costing 60 to 80 percent less than mined diamonds of the same specifications. They are optically and chemically identical to mined diamonds, conflict-free, and fully traceable, which makes a certified pair of studs one of the best values in fine jewelry.
How big is a 1.16 carat total round diamond stud earring?
In this pair the 1.16 carats are split between two diamonds of about 0.58 carat each, so each stone measures roughly 5.3 mm in diameter. That is a versatile everyday size — clearly present on the ear without reading as oversized — and reads larger than its carat weight because of the light-first martini setting.
What is the best diamond shape for stud earrings?
Round brilliant is the most popular and versatile shape for diamond studs. Its 57 to 58 facets maximize light return and sparkle, it flatters every ear, and its symmetry makes matching a pair straightforward, which is why it is the classic choice for a timeless stud.
