Really pleased with Burma Ruby
Hi Ron, Just wanted to let you know that I am really pleased with my [1.16 ct] Burma Ruby that I recently purchased. The color is fantastic and the price was very reasonable. I will shop with ajs gems again. Thanks for all your help in picking out the right ruby. Best regards,

Exceeded my expectations
No question--just an endorsement--Ron recently sent me an amethyst and an imperial topaz in one of his settings--Both are exquisite stones--had a clear day with strong sunlight here and looked at them again--strong sunlight is the best way to see a stone--both stones: great cuts and extraordinary clarity. I have never seen such stones as these---If you want quality stones, AJS provides them ... Every one I have purchased has exceeded my expectations. Well done, Ron --and feel free to put his review on your website.

AMAZING Blue Sapphire pair
The sapphires [1.97 ct Blue Sapphire matched pair] are AMAZING and I am VERY pleased!! They blend well with the sapphire on my ring even though that one has a hint more violet. I can’t believe I’m so lucky to get them. Thank you so much!
