Our verdict
A good fit for a buyer who knows the total carat weight they want, from 2 carat at $2,998 to 7 carat at $10,500, and is happy with 14k white gold. Look elsewhere if you want yellow or rose gold, or need the width, weight and stone count confirmed for the carat option you pick; the listing gives one set of those figures for all six.

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.

- Two sizes are offered, 6.5 and 7
Worth noting
- Only 14k white gold is offered
- The listing shows one width, stone count and weight for all six carat options and does not say how they vary
- No per-stone carat weight is given
Questions before you buy
What do the carat options cost?
The listing prices them by total carat weight: 2 carat $2,998, 3 carat $4,100, 4 carat $5,500, 5 carat $7,000, 6 carat $8,999 and 7 carat $10,500.
Which metal and sizes are offered?
14k white gold only, in sizes 6.5 and 7. The listing says rhodium plated: white gold only, and gives a box clasp.
What does the listing say about the diamonds?
It lists round diamonds with the creation type given as lab grown, near colorless (F-G) color, white hue, clarity SI1+ and a count of about 69, with no per-stone carat weight.
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).
