Frequently Asked Questions

Key guidance for purchasing certified 1 carat lab grown diamonds.

Direct from an Indian manufacturer like New Origin Diamonds in Surat, a top-tier certified 1 carat lab grown diamond (D-F color, VVS/VS clarity, Triple Excellent cut) costs between $350 and $520 USD. In US retail stores, you will typically pay $1,200 to $1,800 USD for the identical certified stone.

A classic 1 carat round brilliant cut diamond measures approximately 6.50 mm in diameter. An oval 1 carat diamond measures around 7.70 × 5.70 mm, providing a visibly larger surface spread on the finger. An emerald cut 1 carat measures approximately 6.50 × 4.75 mm.

For maximum value and optical brilliance, choose **F Color and VS1 Clarity** with an **Ideal/Triple Excellent Cut**. This combination is 100% icy white, completely eye-clean, and allows optimal fire and scintillation without paying a needless premium for D Flawless grades.

Yes, 100%. Because lab grown diamonds are composed of pure carbon in a cubic crystalline lattice, they have identical thermal and electrical conductivity to mined diamonds and pass standard jeweler diamond testers as genuine diamond.

Absolutely. All major jewelry insurance companies (including Jewelers Mutual, BriteCo, and homeowner policies) insure lab grown diamond jewelry based on its replacement appraisal and IGI or GIA grading certificate.
