IGI (International Gemological Institute) independently grades each diamond for cut, color, clarity, and carat weight. Every DEEVE lab grown engagement ring includes an IGI certificate — verifiable at [igi.org](https://www.igi.org). Are lab grown diamonds real diamonds? Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds — same hardness (10 Mohs), same brilliance, same fire. They are not simulants like cubic zirconia or moissanite. What cuts are available? Round brilliant, oval, cushion, princess, radiant, and emerald cuts — in solitaire, pavé, halo, and split shank settings. [Browse the full collection](/collections/lab-grown-diamond-engagement-rings) or shop by cut above. What carat sizes are available? 0.75ct to 5.00ct center stone. Because lab grown diamonds cost 50–70% less than equivalent natural stones, larger carat weights are far more accessible for the same budget. What metal options are available? Solid 14K yellow gold, 14K white gold, and 14K rose gold. Never plated, filled, or vermeil. All hypoallergenic and built for daily wear. Do these rings come with a warranty? Yes. Every DEEVE ring includes a lifetime warranty. [Full warranty details here](/pages/warranty-commitment). How fast is shipping? Free worldwide shipping via UPS Worldwide Saver express.
