Our verdict
A sound choice for a buyer who wants a tennis bracelet with the grades and length written out: 56 round stones, 3.875 ctw, D-E color, VS2+ clarity, excellent cut and 7 inches, at $3,750. Look elsewhere if you need a different length or a width in millimeters, or paperwork for the stones; the listing gives neither.
- Best for
- Someone who wants a flexible 7 inch tennis bracelet with color, clarity and cut grades listed.
- Skip if
- You need another length, a stated width or a certificate for the stones.
Why 3.8/5: Lifted by a spec sheet that includes cut, clarity, color, length and clasp, plus one price for all three metals; held back by the lack of a width and of a stated certificate.
A flexible build is what the store stresses for this tennis bracelet: 56 round lab-grown diamonds in prongs, 3.875 ctw in total, in 14k gold, 7 inches long with a push button clasp. The stones are graded colorless (D-E) with VS2+ clarity and an excellent cut. It costs $3,750 in white, yellow or rose gold.

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.

Questions before you buy

Colorless (D-E) color, white hue, clarity VS2+ and an excellent cut, for 56 round diamonds of 0.07 ct each, totaling 3.875 ctw. The creation method is given as lab-grown diamond.
How long is the bracelet and what is the clasp?
The listing gives a length of 7 inches, a push button clasp and a weight of 9.99 g.
Which metals are available?
14k white, yellow and rose gold at $3,750 each, with rhodium plating for 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).
