What’s New at Precision Gem

Until I can get my arms around this European Union GDPR thing, there are no sales and shipments to the European Union. This process is a bit complicated and not all that clear, and I don't think it fair to pass the expense of meeting the GDPR requirements on to my non European customers. There are stiff fines for not complying, which would put me right out of business. Once I can get a better understanding of what is required to comply, and the costs involved, maybe we can't restart business in the EU, and attach a cost adder to sales into the EU to cover the expense without forcing me raise prices for everyone else in the world. These types of government regulations cripple small businesses, but maybe that was the intent.

If you are in the EU and have signed up for my email list, please remove yourself from the list.

Currently I am not taking on any commissioned work. Watch this page as new stones are added as I cut them. Updates are normally made every week.

I recommend this app to anyone interestes gemstones. Often people will write me asking about the color of stone and use words such as "midnight blue" or "wine color" etc. Well, here is a much better way to describe color, and it's a free app.

You can now use Apple Pay through iMessage to pay for your stones. To pay with Apple Pay, you must of course have an iPhone and be running the latest IOS 11.2 or newer. During checkout, select Apple Pay Cash as your payment method. You won't be billed anything until I receive your order email, at which time I'll text you a payment request. Make sure you include your iPhone cell number or email associated with your iMessage account.

Here's some more information on this new payment method from Apple

Coupon codes are back!

With the new shopping cart, I can have some more options, so there may be some new codes coming. Right now I have set up the “No return” coupon code again.
The code is: NORETURN, using this code, you will get a 5% discount, but there is no return privilege on the stone then.
The coupon code is entered in the shopping cart.

Note, the NORETURN coupon code is not valid for lab created stones.

Follow on Twitter as from time to time I will Tweet out a Coupon Code for special sales.

Latest Cut Stones at Precision Gem

I am cutting new stones every week. After 3 or 4 are cut, I will post the new stones on this page, along with some comments and maybe even a video about them.
When I make a new posting I will always do a Twitter tweet about them, and send out a notice on the email list.

4 new stones today, all Sapphires, yet all quite different. I have priced the Montana based on the rough cost, and not the typical inflated price you have been seeing the past 4 or 5 years for these stones. Montana sapphire rough is less expensive to buy than similar quality sapphire from Africa, there is no reason for these prices of $1000 to $2000 per ct I see.

Cut Stones - Video

Videos are taken with iPhone X outdoors in natural lighting.

My good friend King Errisson wearing one of my stones at The Greek!

I have known King for many years, and cut this Star Cut stone for him about 10 years ago. The stone is a 17 carat Citrine with a frosted star that King had set into the heavy gold chain. He wears it every time he is on stage playing with Neil Diamond, who he has been a part of Neil's band now for over 40 years! The video was taken from a concert at The Greek Theater in LA.

I also cut this large Umbalite garnet for Neil, with a frosted Diamond in the Pavilion. Garnet is his January birthstone.
