Our verdict
A cluster stud for someone who prefers many small round lab-grown diamonds to one larger stone, at $1,100 in any of three 14k gold colors. Look elsewhere if you need the stud size, since the listing gives no dimensions, or a named certificate, which it does not mention. Read the description with care, because it speaks of three diamonds while the spec lists 14.
- Best for
- Someone who wants cluster studs built from small round lab-grown diamonds in 14k gold.
- Skip if
- You need stud dimensions or a named certificate in the listing.
Why 3.8/5: Lifted by a full spec sheet that gives stone grades, count and weight, and by one price across all metals; held back by a description that does not match the stone count, a title weight that differs from the listed total, and no stated certificate.
JNCY sells this pair as a cluster stud: 14 round lab-grown diamonds in prong settings, listed at .98 total carat weight, on push backs. The metal is 14k gold in white, yellow or rose, and every one of the 3 variants costs $1,100. The listing grades the stones colorless (D-E), clarity VS2+ and excellent cut, and gives a weight of 2.74 g.

Metal color is the only choice: 14k white gold, 14k yellow gold or 14k rose gold, which makes 3 variants at $1,100 each. Rhodium plating is listed for white gold only. There are no size options, and the listing gives no stud diameter, only the count of 14 stones and an average of .07 ct per stone.
How it compares
The 1 ctw Round Lab Grown Diamond Three-Stone Drop Earrings also list $1,100, but as a drop style with 1.00 total carat weight, against .98 here. The 1 1/2 ctw Lab Grown Round Diamond Certified Stud Earrings list $995 with a round, prong-set stone in near colorless (F-G), and the 1 ctw Emerald Cut Lab Grown Certified Diamond Stud Earrings list $900 with emerald-cut stones.
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
- Stone grades are stated: colorless (D-E), clarity VS2+ and excellent cut
- 14 stones at an average of .07 ct each, so the .98 total carat weight is spread across many small diamonds
- Three gold colors at one price of $1,100
- Push back closure and a weight of 2.74 g are listed
Worth noting
- Each stone averages only .07 ct, so the stones are small individually
- The title says 1 ctw but the listing gives .98 total carat weight
- The listing gives no stud diameter or other dimensions
- Rhodium plating is listed for white gold only
Questions before you buy
What stones are in these cluster studs?
The listing names diamonds with the creation method lab-grown diamond: round, count 14, colorless (D-E), clarity VS2+, excellent cut, set in prongs. The total carat weight is given as .98, with an average of .07 ct per stone.
Which metals are offered?
14k white gold, 14k yellow gold and 14k rose gold, 3 variants in all, each priced at $1,100. Rhodium plating is listed for white gold only, and the back type is a push back.
Does the listing mention a certificate?
No. It gives color, clarity and cut grades but names no grading report or certificate for these studs.
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 1 ctw, but the listing gives a total carat weight of .98.
- The description speaks of a trio of three diamonds, while the stone details list a count of 14, so the text and the spec do not agree.
- The listing gives no stud diameter and does not say whether the stones are certified.
- 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).
