Our verdict
Suits someone who wants a 2 mm curved band with 19 lab-grown diamonds and a stated .167 total carat weight at $800 in any of three golds. Look elsewhere if you want a larger diamond total or a certificate for the stones; the listing gives neither. The main caveat is the unexplained 9.50 inch length line and the round-versus-marquise mismatch.
- Best for
- Someone who wants a 2 mm curved band with a small diamond total in three gold colors.
- Skip if
- You want a larger diamond total or a certificate stated in the listing.
Why 3.8/5: Lifted by a full spec sheet with stone count, grades and total carat weight, and one price across 78 variants. Held back by an unexplained 9.50 inch length, the round versus marquise mismatch and no stated certificate.
The 1/6 ctw in this band's name refers to 19 lab-grown diamonds, listed at .167 total carat weight, set into a 2 mm curved band. JNCY offers it in 14k white, yellow or rose gold, with the 26 size values from 4 to 10 making 78 variants. Every variant costs $800.

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, one free resizing in the first year for standard ring sizes 4 to 10 (not eternity bands) and two free cleaning visits; 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
- 19 lab-grown diamonds with stated color (F-G), clarity (SI1+) and .167 total carat weight
- Every metal and size is priced at $800
- Width of 2 mm and weight of 3.50 g are given, along with plating status
Worth noting
- Each diamond is .008 carat weight, so the total comes from the stone count
- The description names round and marquise stones, but the diamond details list round only
- The listing shows a 9.50 inch length without explaining what it measures on a ring
- No certificate is mentioned
Questions before you buy
How much diamond is in this band?
The listing gives 19 lab-grown round diamonds, .008 carat weight each and .167 total carat weight. The title says 1/6 ctw.
What grades are given for the diamonds?
Near colorless (F-G) color, white hue and clarity SI1+.
Which metals and sizes are offered?
14k white, yellow and rose gold in sizes 4 to 10 (26 size values). All 78 variants are $800, and the plating line names rhodium 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.
Does JNCY resize rings?
The warranty page offers one complimentary resizing within a year of purchase for standard ring styles in sizes 4 to 10, up or down one size, except eternity bands; larger changes may cost extra, and rings resized by another jeweler lose the warranty.
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
