Our verdict

Suited to someone who wants an emerald-shaped 1 ctw lab-grown diamond on a 2.5 mm band at $1,500, with IGI named as the certification. Look elsewhere if you want a narrower band or need a report number in the listing. The main caveat is that the description line mentions only rose gold while three metals are sold.

Skip if
You prefer a narrower band or need a certificate number printed in the listing.

Why 3.8/5: Lifted by a full spec sheet with width, weight and stone grades and an IGI mention; held back by the missing report number and by description and style lines that do not match the title and options.

JNCY pairs a 2.5 mm wide band with a single emerald-shaped lab-grown diamond of 1 ctw in this solitaire. The metal is 14k white, yellow or rose gold, with 25 sizes in each, which makes 75 variants that all cost $1,500. The listing gives colorless (D-E) color, VS2+ clarity, an excellent cut and IGI as the certification.

Options and pricing

Choose 14k white, 14k yellow or 14k rose gold in sizes 4 to 10, 75 variants in all, each priced at $1,500. The listing limits rhodium plating to the white gold version. Its description line mentions the ring in 14k rose gold, but the variants cover all three colors. A weight of 2.3 g is listed without a metal named.

How it compares

The 1 ctw Emerald Lab Grown Certified Diamond Solitaire Engagement Ring also lists an emerald-shaped diamond at 1.00 ctw on a 1.8 mm average width and costs $1,800, against $1,500 and 2.5 mm here. The 1 ct Round Bezel Solitaire Engagement Ring starts at $1,250 and has a round stone in a bezel, while the 1.33 ctw Pear Lab Grown Diamond Classic Pave Engagement Ring lists $1,750 with a pear stone in a pave style.

Shipping, returns and warranty

JNCY ships by USPS at no cost and says in-stock items such as this one go out within one to four business days (FedEx 2Day is $25 on US orders). 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. The listing mentions a diamond certificate; check the report number against the listing when the piece arrives and keep the paperwork, because JNCY charges $100 for a missing one on returns. Payments accepted include major cards, Affirm, Shop Pay and PayPal.

What we liked

  • A 2.5 mm width and a 2.3 g weight are stated, which describes the band's size
  • Colorless (D-E) color, VS2+ clarity and an excellent cut are listed for the 1 ctw emerald-shaped diamond
  • IGI is named as the certification for the diamond
  • One price of $1,500 across 3 metals and 25 sizes

Worth noting

  • The listing gives no report number to go with the IGI certification
  • The style field says Wedding even though the title calls the piece an engagement ring
  • No stone dimensions in millimeters are given, so the emerald shape's length and width are not stated

Questions before you buy

What diamond is in the 1 ctw emerald wide band solitaire?

One emerald-shaped lab-grown diamond of 1 ctw with colorless (D-E) color, white hue, VS2+ clarity and an excellent cut. The listing gives IGI as the certification.

How wide is the wide band and how much does it weigh?

The listing gives a width of 2.5 mm and a weight of 2.3 g.

Which metals and sizes does the emerald wide band come in?

14k white, 14k yellow and 14k rose gold, in sizes 4 to 10, with all 75 variants priced at $1,500. The rhodium plating line names 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 in-stock items ship within one to four business days by USPS at no cost, and FedEx 2Day costs $25 on US orders. Signature is required on engagement rings and orders over $1,500.

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).
