Frequently Asked Questions

What is IGI certification?

The International Gemological Institute (IGI) is one of the world's leading gemological laboratories. Every Lihara diamond comes with an IGI grading report that independently verifies the stone's cut, color, clarity, and carat weight. This gives you an objective, third-party guarantee of exactly what you're buying.

Do all Lihara diamonds include an IGI report?

Yes. Every diamond in our collection is IGI certified. Your certificate ships with your order and is also available digitally via the IGI website using your stone's report number.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. They have the same crystal structure, hardness (10 on the Mohs scale), and optical properties. The only difference is their origin.

What color and clarity grades do Lihara diamonds carry?

All Lihara diamonds are D–F color (colorless) and VS+ clarity (VS1, VS2, or better). These are the grades that represent the finest quality in both mined and lab-grown diamonds.

What does VS+ clarity mean?

VS stands for Very Slightly Included. VS+ means VS1 or better — inclusions are minor and invisible to the naked eye. Under 10x magnification they are difficult to see. Eye-clean guaranteed.

What does D–F color mean?

D and E are the two highest color grades on the GIA/IGI scale, representing colorless diamonds. These stones appear completely white and brilliant, with no visible yellow or brown tint.

How long does shipping take?

Because each piece is made to order, please allow 5–10 business days for production. Express shipping is available at checkout. All orders ship insured with signature required.

What is your return policy?

We accept returns within 30 days of delivery for a full refund, provided the item is unworn and in original condition with all packaging. Custom or engraved pieces are final sale.
