Our verdict
A direct choice for someone who wants a four-prong pair of round diamond studs at 0.50 total carat weight in white or yellow gold for $300. Look elsewhere if you need a certificate or a narrower clarity grade than VS, or if the crossed-out $350 is what makes the price attractive; it is the store's own comparison, not a market price.
- Best for
- Someone who wants a simple pair of four-prong diamond studs in white or yellow gold.
- Skip if
- You need a certificate or a clarity grade narrower than VS.
Why 3.8/5: Lifted by a full spec sheet with stone grades, size, setting and backing, and a clear price across two metals; held back by the absence of a stated certificate and a clarity grade given only as VS.
Two round lab-grown diamonds of 0.25 ct each make up this pair of studs, which JNCY lists at 0.50 total carat weight in four-prong settings. They come in 14k white or yellow gold with push backs for $300, a price the store shows beside a crossed-out $350. The listing gives clarity as VS and color as near colorless (F-G).

Rhodium plating applies to white gold only. The listing gives an earring length of .25 and a width of .25, both in inches, with a push back closure, and no other carat weights are offered on this page.
How it compares
The Diamond Bezel Door Knocker Earrings list $582 in 14k yellow gold with a total carat weight of 0.03, against 0.50 for these studs at $300. The Enamel Cross Stud Earrings list $468 in 14k yellow gold, and the Paperclip Dangle Earrings list $328 in the same metal.
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. Payments accepted include major cards, Affirm, Shop Pay and PayPal.
What we liked
- Two round lab-grown diamonds with 0.50 total carat weight, F-G color and VS clarity listed
- Two metals, 14k white or yellow gold, at one price of $300
- Earring size, backing and setting are stated
Worth noting
- Clarity is listed only as VS, with no narrower grade
- The crossed-out $350 is the store's own figure and cannot be checked against a market price
- No certificate or grading report is mentioned
Questions before you buy
What are the stones in these stud earrings?
Two round diamonds with the creation type given as lab grown, 0.25 ct each and 0.50 total carat weight, near colorless (F-G) color, white hue and clarity VS, in a prong setting.
Which metals and backs are listed?
14k white gold and 14k yellow gold at $300 each, with rhodium plating on white gold only and a push back closure.
How big are the studs?
The listing gives an earring length of .25 and a width of .25, both in inches.
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).
