Luminary Gem — Frequently Asked Questions
Are your engagement rings made with lab-grown diamonds?
Yes. All Luminary Gem engagement rings are crafted using certified lab-grown diamonds, each accompanied by an IGI certificate for quality and authenticity.
Does every engagement ring come with a certificate?
Yes! Every engagement ring comes with two certificates:
- An IGI diamond certificate, clearly detailing the diamond’s grade, cut, color, clarity, and carat weight.
- An IGI card certificate, clearly describing the gold type, metal weight, and other specifications of the finished ring.
These certificates ensure authenticity, transparency, and confidence in your engagement ring purchase.
How long does it take to receive a custom engagement ring?
Every engagement ring is made to order. Production typically takes 2–4 weeks, followed by secure shipping. You will receive tracking information once your ring ships.
