Absolutely thrilled with my recent purchase from Lusterblue! I recently purchased a stunning natural teal sapphire and had it custom designed into an engagement ring. The craftsmanship is impeccable, and their customer service was incredibly throughout the process. I couldn't be happier with the final result. Highly recommend!
