Art Nouveau Oval Lab Grown Diamond Engagement Ring
An Art Nouveau engagement ring set with an oval cut lab grown diamond. Every ring is made to order and handcrafted by Mapple Gems in Surat, India, and every center stone ships with a free IGI certificate. Where Art Deco is built on straight lines and symmetry, Art Nouveau takes its shapes from nature, so the band curves and tapers with organic vine and leaf detail rather than a rigid geometric frame.

Frequently asked questions
Is a lab grown diamond a real diamond? Yes. A lab grown diamond has the same carbon crystal structure, hardness and brilliance as a mined diamond. The only difference is that it is grown in a laboratory rather than extracted from the earth. It is graded by the same laboratories using the same criteria.
What color and clarity are the diamonds in this ring? Both the oval center stone and the round brilliant side stones are E color and VVS2 clarity. E is in the colorless range, and VVS2 means inclusions are very difficult to see even under ten times magnification, so the stones are completely eye clean.
What is the difference between Art Nouveau and Art Deco? Art Nouveau came first, running from roughly 1890 to 1910, and draws on nature with flowing curves, vines, leaves and asymmetry. Art Deco followed in the 1920s and 1930s and rejected that in favour of hard geometry, straight lines and symmetry. This ring is the Nouveau side, so it reads softer and more organic.
Why choose an oval cut for an engagement ring? An oval cut has a larger surface area than a round brilliant of equal carat weight, so it appears bigger on the hand. Its curved outline also suits Art Nouveau design better than an angular cut would.
Does this ring come with certification? Yes. Every center stone ships with an IGI certificate at no additional charge. IGI is one of the largest independent gemological laboratories grading lab grown diamonds.
Is this ring in stock? Every Mapple Gems ring is made to order rather than held as stock, so it is always available to buy. Production typically takes 7 to 10 business days before shipping.
Can this ring be customized? Yes. Stone shape, carat weight, metal, band width and color or clarity grade can all be changed, and we also build fully custom designs. Contact us through https://mapplegems.com/pages/contact to start a custom order.
