Good luck as you retire
We are sooo looking forward to this piece being very special!
A few years ago we purchased a very large cushion peridot as well as matching ovals that were made into earrings.
We love them and have had many compliments .
Thank you.
Good luck as you retire.
If you would like I can email a photo of our pieces that we purchased from you.

I love every single piece that I purchased from you
Hello Arnold,
Thank you for sending me the email and the 25% discount offer. I'm very sad to hear that you will close your business. I love every single piece that I purchased from you. However I do wish you will enjoy your retirement life soon.
I am planning to make some purchase before the discount expires, however my family all got sick last week and we just recovered. I just wondering if you could still honor the discount for me? Thank you very much and looking forward to hear from you soon.
Bests,

AJS Gems is known across many continents
Dear Arnold,
I am afraid I mised this email somehow. I guess the offer is now closed? I am interested in the two blue star sapphires, one from Ceylon, the other from Burma.
And I am very sorry to hear of your retirement. You have been a major figure in this field in Asia, and AJS Gems is known across many continents.
I wish you the best in your retirement.
