Our verdict
An oval-stone stud pair for someone who wants 1.00 ctw of lab-grown diamonds in 14k white or yellow gold at $1,750, with color and clarity stated. Look elsewhere if you need rose gold, a cut grade, or the certificate identified; the listing offers or names none of these.
- Best for
- Someone who wants oval lab-grown diamond studs at 1.00 ctw in white or yellow gold.
- Skip if
- You need the certificate identified or a cut grade stated 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 a description that names round stones instead of oval and by the missing certificate details.
Oval stones are the point of these JNCY studs: the listing gives 2 oval lab-grown diamonds at .50 ct each, 1.00 ctw in total, held by prongs on push backs. They come in 14k white or yellow gold, 2 variants, both at $1,750. The title calls the diamonds certified, and the stone details give near colorless (F-G) color and VS clarity.

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
- Oval shape with a stated count, .50 ct per stone and 1.00 ctw in total

- Two gold colors at one price of $1,750
Worth noting
- No cut grade is listed
- Only white and yellow gold are offered, with no rose gold
- The title says Certified, but the listing names no grading lab or report
Questions before you buy
What diamonds are in these oval studs?
The stone details list 2 oval lab-grown diamonds of .50 ct each, 1.00 ctw in total, with near colorless (F-G) color and VS clarity, in a prong setting.
Does the listing say the diamonds are certified?
The title says Certified, but the listing text does not name a grading lab or give a report number.
Which metals and sizes are offered?
14k yellow gold and 14k white gold, 2 variants at $1,750 each. The listing gives .25 in length and .17 in width, with a push back and rhodium plating on white gold only.
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).
