Our verdict
Suited to someone who wants a princess-shaped 2 ctw diamond with an excellent cut grade and IGI named, at $2,750. Look elsewhere if you need the listing's carat figures to agree or want a report number. The main caveat is the 1.00 versus 2.00 total carat weight inside the same listing.
- Best for
- Someone who wants a princess-shaped 2 ctw solitaire with the cut grade and IGI stated.
- Skip if
- You need the carat figures in the listing to agree or want a report number stated.
Why 3.9/5: Lifted by a full spec sheet with a cut grade and the certified wording in the title; held back by the conflicting total carat weight and the missing report number.
The single stone in this JNCY solitaire is a princess-shaped lab-grown diamond of 2.00 ct, listed as colorless (D-E) with VS2+ clarity and an excellent cut. It sits in prongs on a 1.8 mm band in 14k white, yellow or rose gold, in sizes 4 to 10. The 75 variants are all $2,750, and IGI is named as the certification.

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 princess-shaped diamond of 2.00 ct with colorless (D-E) color, VS2+ clarity and an excellent cut stated
- IGI is named as the certification, and the title calls the diamond certified
- Prong setting, a 1.8 mm average width and a 3.4 g weight are listed
- A single price of $2,750 for 3 metals and 25 sizes
Worth noting
- The ring information shows a total carat weight of 1.00, at odds with the 2.00 ct in the diamond details
- No report number accompanies the IGI mention
- No stone dimensions in millimeters are given for the princess diamond
Questions before you buy
What are the stone details of the 2 ctw princess solitaire?
One princess lab-grown diamond of 2.00 ct, colorless (D-E), white hue, clarity VS2+ and excellent cut. The listing names IGI as the certification.
Which metals and sizes does the princess solitaire come in?
14k white, yellow and rose gold in sizes 4 to 10. All 75 variants are $2,750, and rhodium plating is listed for white gold only.
Is the princess solitaire's carat weight 1.00 or 2.00?
The title and the diamond details say 2 ctw and 2.00, while one line of the ring information says a total carat weight of 1.00. The listing gives no reason for the difference.
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).
