Frequently Asked Questions
Exquisite Service & Craftsmanship
What are Lab Diamonds, and are They Real Diamonds?
Lab-grown diamonds are real diamonds in every physical sense—the only difference is how they are made. Their biggest advantage is that they allow you to get a larger size and higher quality (cut, clarity, color) for less money, making them a popular choice for engagement rings and fine jewelry. Lab-grown diamonds typically cost 60% to 90% less than natural diamonds of the same size and quality.
Do your lab-grown diamonds and gemstones come with certifications?
Absolutely. Every DEASTRA lab-grown diamond and gemstone comes with a Certificate of Authenticity that details its carat weight,cut, clarity, color, and measurements. This gives you full transparency and confidence in exactly what you are purchasing: genuine, ethically crafted fine jewelry you can trust.
Does DEASTRA offer extended coverage for wear-and-tear?
Our Extended Protection Plan goes beyond the lifetime manufacturing warranty, covering accidental damage and helping keep your jewelry looking like new. Benefits include free ring sizing after the initial 30-day window, rhodium plating for white gold jewelry, professional polishing and refinishing, and other care services to maintain brilliance.
