9999 Solid 24k Gold 2 Round Jade Pendant 12.7 Grams Handmade Custom Longevity. DISCLOSURE – depending on the test method, purity of gold “may” vary from the industry standard threshold of 23.5k +- 0.25k due to soldering. GIA seems to be calculating solder as part of purity results. Because of this, I’ve titled this listing at 24k, but under item specifics, I selected 23k to avoid this continuous issue. Upon receiving your item, feel free to have it tested. Acid test, electronic test, etc.. If it doesn’t test 24k, contact me. I stand behind my products and will resolve any concerns. Please contact me with any questions you may have. I’m easy to work with and will consider all reasonable offers. Additional pictures are available upon request.
