About Lab Grown Diamonds
Lab grown diamonds are real diamonds — chemically, optically, and physically identical to mined diamonds, and graded by the same independent laboratories (IGI, GIA). The only meaningful difference is that they are grown in weeks rather than formed over billions of years.
Choosing lab grown means a larger, cleaner, more colorless stone for your budget, with a transparent origin and no mining footprint. This diamond is IGI certified — you can verify its grades directly on the IGI portal.

Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined diamonds. This center stone is a colorless, VVS2 clarity diamond, IGI certified.
What is an old mine cut?
The old mine cut is an antique, cushion-shaped cut with a high crown, small table and larger, hand-cut facets. It gives softer, more romantic flashes of light than a modern brilliant — a genuinely vintage character in a brand-new stone.
What is a three-stone setting?
The old-mine-cut center is flanked by two oval white diamonds — 1.44 carat of side stones in total. The three-stone design is a classic symbol of a couple's past, present, and future.
What metals can I choose?
10K, 14K or 18K solid gold in yellow, white or rose, or platinum. The ring shown is 14K yellow gold.
Can this ring be resized?
Yes — complimentary resizing within the first year.
How much does this ring cost?
The Eleanor starts at $3,030 in 10K solid gold, $3,240 in 14K, and $3,450 in 18K gold or platinum.
What's included with my ring?
The IGI® grading report, a signed Mohana certificate of authenticity, free worldwide insured shipping, a lifetime craftsmanship warranty, and a 30-day return window.
How long does it take to make and ship?
Each ring is handcrafted to order in 1–2 weeks, then ships free worldwide with full insurance.
