Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A classic anniversary ring set with a cushion 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. The setting is deliberately restrained, using a four prong head on a tapered band so the ring stays timeless rather than tied to any one period style.
Choose from 925 sterling silver, or solid 10K, 14K or 18K gold in yellow, rose or white. All gold is solid, not plated or filled.
Select your US ring size on this page before adding to cart. If you are unsure of your size, contact us and we will send a free ring sizer.
Every piece is made to order, so this ring can be adapted to what you want. We can change the center stone shape or carat weight, swap the metal, adjust the band width, set a different color or clarity grade, or build a completely new design from a picture or sketch you send us. If you want any other customization, contact us through https://mapplegems.com/pages/contact and we will prepare a CAD design for your approval before we begin.
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 cushion cut center stone and the accent 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.
Why choose a plain setting over a period style? A period style ring ties the design to a specific era, which some people love and others tire of. A restrained four prong setting keeps attention on the stone and tends to age better if you expect to wear the ring for decades.
How many prongs should hold a cushion cut? Four is standard for a cushion, with one prong on each rounded corner. Corners are the most exposed part of the stone, so setting the prongs there protects the cut while keeping the table fully open to light.
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.
