Review and sources
Reviewed by Beylora on September 20, 2026. We checked every linked Bellagio configuration and price in this guide against Beylora’s current Shopify catalog, checked the matching 2-carat comparison, then reviewed the current Shipping and Refund policies.
We compare complete-ring prices before tax and optional Rush using the same design and metal, distinguish center-diamond carat weight from the complete ring, and calculate price differences from the live configurations named in the article. Diamond-grade context follows the individual IGI report fields described in our IGI report guide. Prices and availability can change, so confirm the selected product page before ordering and contact us before relying on an arrival date.
Is this a loose-diamond price or a complete-ring price?
The prices in this guide are for complete engagement rings. Beylora sells the selected center diamond and setting together, so there is no separate loose-diamond purchase to add. A loose-diamond quote covers a different purchase: add the chosen setting and ask what the finished ring will cost before comparing totals.
Compare the same lab-grown origin, center carat weight, grading specifications and metal. A quote for a 3-carat natural diamond, a loose lab-grown diamond and a complete lab-grown ring can describe three different products.

Does 3 carats mean the center diamond or the whole ring?
In these Beylora configurations, 3 carats refers to the lab-grown center diamond. The complete-ring price also includes the setting and any accent stones in the design. A wedding band is separate. Read what is included in the ring price.
Beylora's lab-grown centers are D color and VVS clarity (VVS1 or VVS2), with an individual IGI report covering the center diamond. Check the exact stone's report number and measurements using the IGI report guide.
How can I judge whether 3 carats will suit my hand?
Compare the center diamond's length and width in millimeters, the setting height and your ring size. Carat measures weight; the number alone does not give the diamond's visible dimensions. Ask for the available views and specifications of the design you are considering before choosing.
For the width of a round diamond at 1, 1.5, 2, 2.5 and 3 carats, see 1 carat vs 2 carat lab-grown diamond.
