18K Brilliant White Gold Information Sheet
| 18K BRILLIANT WHITE GOLD (18H) - white gold index grade 1 casting alloy - 0.752 gold, copper, nickel, zinc |
|
The greatest complaint with white gold jewelry is that "the ring is turning yellow". Jewelers know this is not the case and in fact the rhodium plating is wearing off, exposing the poor color of the white gold alloy underneath. Hoover & Strong Brilliant White casting grains are a development from customer requests for "whiter" gold alloys and are rated grade 1 on the MJSA White Gold Index, so your finished castings will have a color that will not need Rhodium plating. If you do choose to rhodium plate, with Hoover and Strong’s Brilliant White gold alloys any wear on the plating is virtually unnoticeable. Brilliant White gold alloys still retain excellent casting characteristics. Recommended Uses: 18K Brilliant White is a premium color white gold alloy for use in all investment casting applications. |
