Re-sizing or re-building to another size with the same gemstones is free!
Re-sizing one of our rings can often be done quite easily by hammering and re-polishing when only increasing by a size or so and there will be no noticeable delay in the shipping time. When we need to have the size decreased at all or increased by more than about one size then I have to ask you to be patient as it will need to re-enter the queue and will be ready for shipping in about 30 days. Right after you make the purchase be sure to message me about the new size before I have a chance to ship.
Thailand’s Gem Markets
Being a gemologist in Thailand makes providing you with the right gemstones a snap. Furthermore, the gem markets here are nothing short of amazing! We shop in four different gem districts across the country and the variety is world class. Additionally, a precision gem cutter is working for our operation. Of course, we also source fine gemstone rough with our worldwide network of contacts in the mining business.
Since I love to travel and shop for gemstones, I do act as a buyer’s guide to the gem markets for any visitor that would like assistance. Often I can meet you at a gem market or even pick you up at the airport to get our adventure started.
Custom cut gemstones
An essential part of our service is custom gemstone cutting. You may supply rough stones for us to have precision faceted or cabbed into the shapes that you desire. In addition, many gemstones that are already native cut will be improved in clarity and light return by a new precision cut.
Custom orders on gemstone cutting are normally ready in just two to three weeks. Message me with details of your gemstone requirements. I will provide the address along with special instructions on shipping stones to us.
