I have used them and they fired best at about 1550 for about an hour. However remember that the emerald green and blues turn color when fired at that temperature. **Q: Can these be fired in silver clay with a torch?** A: I have no idea, but it's a very interesting question. It looks like the white tolerate much higher temps than the colored cz. Any idea what temp you need to successfully fire the pmc? I would love to hear if you have success with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for homemade birthday gifts *by S***Y on January 15, 2026* Nice colour, accurate size description, the price is fair and they are perfect for making sudden birthday gifts ### ⭐⭐⭐⭐⭐ Great Item *by T***. on September 23, 2025* Granddaughter love this ### ⭐⭐⭐⭐⭐ Nice colors *by H***E on April 6, 2025* Be sure to know exactly how large or small the jewels you are wanting. ## Frequently Bought Together - JIANGYUANGEMS 12pcs Birthday Stone 1pcs Per Color Round Loose Cubic Zirconia Stones Synthetic Ruby Synthetic Spinel - XIANGMO 5A Oval Cut Loose Cubic Zirconia Stones Mix 15 Colors CZ Stone Synthetic Gemstone for Jewelry Making - JINGANGZUO Square Princess Cut Shape Cubic Zirconia Synthetic Gemstone Mix 15 Colors 5A Loose CZ Stone for Jewelry Making --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/66554047-jiangyuangems-12pcs-birthday-stone-1pcs-per-color-round-loose-cubic](https://www.desertcart.hr/products/66554047-jiangyuangems-12pcs-birthday-stone-1pcs-per-color-round-loose-cubic) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-17*
