Our verdict
A round four-prong stud for someone who wants 2.00 ctw of lab-grown diamonds in white or yellow gold at $1,995, with color, clarity and size stated. Look elsewhere if you need rose gold, a cut grade or the certificate named; the listing offers none of these.
- Best for
- Someone who wants round lab-grown diamond studs totaling 2.00 ctw in white or yellow gold.
- Skip if
- You need rose gold, a cut grade or a named report in the listing.
Why 3.9/5: Lifted by a full spec sheet with stone grades and dimensions and a certified claim in the title; held back by the missing cut grade, the unnamed certificate and no rose gold option.
The listing describes these as four-prong round lab-grown diamond studs, and this 2 ctw version carries 2 stones of 1.00 ct each in near colorless (F-G) color and VS clarity. The metal is 14k white or yellow gold on push backs, and both of the 2 variants cost $1,995. The title says the diamonds are certified.

Shipping, returns and warranty
JNCY ships by USPS at no cost and says most items are made to order, about two weeks, with an estimated ship date on the product page (FedEx 2Day is $25 on US orders and does not shorten production). A signature is required on engagement rings, made-to-order designs and orders over $1,500. It also ships to Australia, Canada, France, Germany, Ireland, Italy, South Korea and the United Kingdom for a flat $50, with duties and taxes paid by the buyer. Returns: 30 days from the ship date for pre-designed styles returned unworn with their original documents, with a free FedEx label on US orders; the FAQ page says 7 days instead, so confirm before relying on 30. Warranty: free lifetime repair or replacement of manufacturing defects and two free cleaning visits in the first year; wear and tear, lost stones and clearance items are excluded.
Before you buy
JNCY Jewelers is a Miami jeweler whose domain was registered in 2020. Independent feedback is thin: a ProvenExpert page lists three ratings, all 5.00, from Facebook and The Knot with no review text, and searches on 19 October 2026 found no Trustpilot or BBB page for the store. JNCY's own pages disagree in places: the refund window is 30 days on the Refund policy page and 7 days in the FAQ, and the custom-bridal page says it offers no financing while the financing page lists several plans. The listing mentions a diamond certificate; check the report number against the listing when the piece arrives and keep the paperwork, because JNCY charges $100 for a missing one on returns. Payments accepted include major cards, Affirm, Shop Pay and PayPal.

Questions before you buy
What are the stones in these studs?
The stone details list 2 round lab-grown diamonds of 1.00 ct each, 2.00 ctw in total, near colorless (F-G) with VS clarity, in a prong setting; the description says four-prong.
Which metals does the pair come in?
14k yellow gold and 14k white gold, 2 variants at $1,995 each, with push backs and rhodium plating on white gold only.
Does the listing call the diamonds certified?
Yes, in the title, which reads Certified. The listing does not name a grading lab or a report number.
Can I return it if I change my mind?
JNCY's Refund policy page gives 30 days from the ship date for pre-designed styles returned unworn with their original documents; US orders get a free FedEx label and international buyers pay return shipping. A missing diamond certificate costs $100. The FAQ page says refunds are possible for up to 7 days after delivery, so confirm the window before relying on 30 days.
How long until it ships?
JNCY says most items are made to order and take about two weeks; the product page, cart and order email show an estimated ship date. USPS shipping is free, and FedEx 2Day ($25 on US orders) does not shorten production.
Are lab-grown diamonds real diamonds?
GIA says laboratory-grown diamonds have the same crystal structure as natural diamonds, tightly bonded carbon atoms, and nearly the same chemical, optical and physical properties. By eye the difference can be indistinguishable, but gemological laboratories can detect the different growth history with advanced instruments. They are grown by high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD).

What we couldn’t verify
- The title says Certified, but no grading lab or report number is given, and no cut grade is listed.
- The length and width are both .25 in, and the listing does not say whether that describes the stone or the whole earring.
- Independent testing or appraisal: we found none for this piece; the only outside feedback is a ProvenExpert page with three 5.00 ratings (two Facebook, one The Knot) and no text.
- JNCY's pages disagree on the refund window (30 days on the Refund policy page, 7 days in the FAQ).
- We have not seen this piece's diamond certificate; the grades come from the listing.
