About Pink Lab Grown Diamonds
Fancy pink diamonds are among the rarest colored diamonds in nature — historically from Australia's now-closed Argyle mine. Lab grown technology makes the romance of a true pink diamond accessible.
Mohana's pink lab grown diamonds are chemically, optically, and physically identical to mined pink diamonds — graded by the same IGI and GIA laboratories. The color is part of the diamond's atomic structure and will not fade.
Frequently Asked Questions
Are these real lab grown diamonds?
Yes. Lab grown diamonds are 100% real diamonds — same crystal structure, same hardness, same brilliance. Every Mohana diamond is certified by IGI or GIA.
How big is a 2.5ct Emerald cut diamond in real life?
A 2.5-carat emerald-cut diamond measures approximately 9×7mm — the elongated step-cut shape makes it look larger on the finger than a round of similar weight. To see how this looks on a real hand and compare against other shapes and carat weights, view our diamond size guide — it includes side-by-side photos and finger-coverage examples for every shape.
How many side stones does this ring have?
The Siena is set with 44 round brilliant diamonds — 16 at 1.5 mm forming the hidden halo beneath the center, and 28 at 1.0 mm running along the pavé band. For exact stone count on your specific configuration, our craft team can confirm before production — contact customer support.
What is the shank width of this ring?
The shank (the band around your finger) measures 2.5mm wide. This balanced width is slim enough to feel elegant on the finger while supporting the pavé diamond band running along the shoulders. The shank width is consistent across all metal options.
How much does this ring cost?
The Mohana Siena starts at $2499 in 10K solid gold and scales up with 14K, 18K, and platinum.
Will the pink color fade over time?
No. The color in a lab grown pink diamond is part of the diamond's atomic structure, not a treatment.
Can this ring be resized?
Yes — complimentary resizing within the first year.
What is a hidden halo setting?
A hidden halo is a ring of small diamonds set beneath the center stone, invisible from above but visible from the side profile.
What's included with my ring?
IGI® or GIA® grading report, Mohana certificate of authenticity, free worldwide insured shipping, lifetime craftsmanship warranty, 30-day returns, and complimentary first-year resizing.
How long does it take to ship?
Handcrafted to order in 1–2 weeks, then ships free worldwide with full insurance.
Can I customize this ring?
Yes — contact customer support to request custom variations.
