FAQs
Q: Are Lightbox lab-grown diamonds real diamonds? A: Yes, Lightbox lab-grown diamonds are real diamonds that have the same chemical and physical properties as mined diamonds. They are created in a laboratory using advanced technology, rather than being mined from the earth.
Q: How do Lightbox lab-grown diamonds compare to mined diamonds? A: Lightbox lab-grown diamonds are visually indistinguishable from mined diamonds and have the same brilliance, fire, and scintillation. However, they are significantly more affordable due to the lower production costs associated with lab-grown diamonds.
Q: Are Lightbox lab-grown diamonds graded? A: Lightbox lab-grown diamonds are not independently graded. Instead, the brand provides broad color and clarity ranges for each stone, such as "near colorless" and "VS to SI clarity". This approach allows Lightbox to keep prices low while still offering high-quality diamonds.
Q: What is Lightbox's return policy? A: Lightbox offers a 30-day return policy on all purchases. If you are not satisfied with your purchase, you can return it for a full refund or exchange, as long as the item is in its original condition and packaging.
