Customer for life
UPS just delivered the custom 1.42 ct. Ruby ring. It. Is. Stunning. Simple and elegant, just how I like it. I can’t stop looking at it! I never understood all the hoopla over “pigeons blood” red until now, until I laid eyes on this Ruby. I could not be happier.
Thank you for your patience answering all my questions and thank you for being friendly, honest and reputable. I also appreciate the insanely fast shipping. Your communication throughout the process put me at ease and the quality and workmanship of the ring are top notch. You have a customer for life and I’ll be sure to tell anybody who’ll listen that AJS Gems did me right. This Ruby is definitely the right investment choice and will be in my family for many generations to come. Thank you again!
