3.75 Carat Pink Lab Grown Diamond Engagement Ring – Marquise Cut Three Stone

Major retailers sell pink diamond engagement rings for $8,000–$25,000 due to the rarity of pink diamonds. Mohana delivers IGI/GIA-certified lab grown pink diamonds at a fraction of that, handcrafted to your specifications, starting at $3500.00.

Fancy pink diamonds are among the rarest colored diamonds in nature — historically from Australia's now-closed Argyle mine, where mined pinks sold for $1M+ per carat. Lab grown technology makes the romance of a true pink diamond accessible without the financial or ethical burden.

Mohana's pink lab grown diamonds are chemically, optically, and physically identical to mined pink diamonds — graded by the same IGI and GIA laboratories using the same scales. The color is part of the diamond's atomic structure, not a surface treatment, and will not fade.

Pink diamonds pair most beautifully with rose gold settings, which amplify the diamond's blush tone. For dramatic contrast, choose platinum or white gold. Explore the full pink diamond collection.

Are pink lab grown diamonds real diamonds?

Yes. Lab grown pink diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined pink diamonds. Every Mohana pink diamond is certified by IGI or GIA.

How many side stones does this ring have?

Two tapered baguette lab grown (6×3×2mm each), 0.75 carat total lab grown diamonds. 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 3.0mm wide. At 3.0mm the band balances the visual weight of a 3.75-carat center in the three stone setting — slim enough to wear daily, substantial enough to hold the design securely. The shank width is consistent across all metal options.

How much does a 3.75 carat pink lab grown diamond engagement ring cost?

The Mohana starts at $3500.00 in 10K solid gold and scales up with 14K, 18K, and platinum. A natural mined pink diamond of comparable size and clarity would cost $500,000 to $2M+.

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. It will not fade over a lifetime of wear.

Can this ring be resized?

Yes — complimentary resizing within the first year. Full eternity bands are the exception due to their continuous diamond setting.

What is a three stone setting?

A three-stone setting flanks the center diamond with two complementary side stones — often symbolizing past, present, and future.

What's included with my ring?

The IGI® or GIA® grading report, a signed Mohana certificate of authenticity, free worldwide insured shipping, a lifetime craftsmanship warranty, a 30-day return window, and complimentary resizing within the first year.

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.

Can I customize this ring?

Yes — contact our team through customer support to request a custom variation in a different carat, shape, or metal combination.
