What moves the price above 5 carats?

• Shape. Rounds cost the most at 10ct; ovals, emerald cuts and pears give more size for the money.
• Cut and measurements. Check millimeter measurements, not just the carat number.
• Color. Color shows more in large stones; D–F is available on every build.
• Clarity. Our standard is VS1 or better, with VVS available.
• Setting and metal. Larger stones need sturdier prongs and gallery work; platinum and 18K add to the 14K estimate.

Every lab-grown center is IGI-certified, and our standard is VS1 clarity or better (D–F color and VVS clarity are available as upgrades). You see a 3D render first, in about 24–48 hours, for a $50 design fee that is fully refundable and credited to your ring, with unlimited revisions. Delivery takes 4–5 weeks after 3D approval and payment, and a $250 rush takes 2–3 weeks (14–21 days). Engraving is complimentary, US shipping is free and fully insured, and every ring comes with a Lifetime craftsmanship warranty, plus a free resize within 60 days.
