Our verdict
Suited to someone who wants a 2.00 ct radiant-shaped diamond in a solitaire at $2,250 with IGI named in the listing. Look elsewhere if you need a cut grade, since the listing leaves it out. The main caveat is that stone dimensions and a report number are not given.
- Best for
- Someone who wants a single radiant-shaped lab-grown diamond at 2 ctw in a solitaire.
- Skip if
- You need a cut grade for the diamond stated in the listing.
Why 3.9/5: Lifted by a full spec sheet and by a title that states the diamond is certified, with IGI named; held back by the absence of a cut grade for the radiant diamond.
JNCY's radiant solitaire carries a single lab-grown diamond of 2.00 ct, with colorless (D-E) color and VS2+ clarity listed. The band is 1.8 mm wide and comes in 14k yellow, white or rose gold across sizes 4 to 10, which makes 75 variants all priced at $2,250. The title calls the diamond certified and the details name IGI, but no cut grade is given.

How it compares
The 2 ctw Round Lab Grown Certified Diamond Solitaire Engagement Ring lists the same $2,250 and 2.00 ctw with a round stone instead of a radiant one. The 2 ctw Marquise Lab Grown Certified Diamond Solitaire Engagement Ring lists $2,750, and the 1.33 ctw Oval Lab Grown Certified Diamond Pave Engagement Ring lists $1,950 at a smaller total weight.
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.

- The style field says Wedding, although the title calls the piece an engagement ring
Questions before you buy
What are the diamond grades on the 2 ctw radiant solitaire?
One radiant lab-grown diamond of 2.00 ct, colorless (D-E), white hue, clarity VS2+. The listing names IGI as the certification and gives no cut grade.
Which metals and sizes does the radiant solitaire come in?
14k yellow, white and rose gold in sizes 4 to 10. All 75 variants are $2,250, and rhodium plating is listed for white gold only.
How wide is the radiant solitaire's band?
The listing gives a width of 1.8 mm and a weight of 2.27 g.
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).
