Our verdict
A pair of four-prong round lab-grown diamond studs at 1.50 total carat weight in white or yellow gold for $995, for someone who wants plain round studs with color and clarity stated. Look elsewhere if the Certified label needs a named lab or report behind it, or if you want a cut grade; the listing supplies neither.
- Best for
- Someone who wants round four-prong lab-grown diamond studs at 1.50 total carat weight.
- Skip if
- You want a cut grade, or a lab or report named alongside the Certified label.
Why 3.9/5: Lifted by a complete spec sheet and the Certified label in the title; held back because no cut grade is listed and no lab or report is named.
At 1.50 total carat weight, this JNCY stud pair has two round lab-grown diamonds of .75 ct each in four-prong settings with push backs. The price is $995 in either 14k white gold or 14k yellow gold. The listing grades the stones Near Colorless (F-G) with VS clarity, and the title says Certified, although no lab or certificate is named.

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.
What we liked
- Two round lab-grown diamonds at .75 ct each with color (F-G) and clarity (VS) stated
- Both 14k white gold and 14k yellow gold at the same $995
- Four-prong setting, push back and .25 in length and width are listed
Worth noting
- The listing leaves out a cut grade for the stones
- A Certified label in the title is not backed by a named lab or certificate in the listing
- Only the white gold version carries rhodium plating
Questions before you buy
What diamonds are in the 1 1/2 ctw studs?
Two round lab-grown diamonds at .75 ct each, 1.50 total carat weight, with Near Colorless (F-G) color and VS clarity, set in four prongs.
Which metals are offered?
14k white gold and 14k yellow gold, both at $995. Rhodium plating is limited to white gold, per the listing.
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).

- JNCY's pages disagree on the refund window (30 days on the Refund policy page, 7 days in the FAQ).
