Treated Quartz Faceting Information
Oro Verde (Quartz)
Color: Gold to yellow/green
Moh’s Hardness: 7
Refractive Index: 1.544-1.553
Critical Angle: 40.49°
Specific Gravity: 2.63-2.65
Heat Sensitivity: Can be. but is usually not a problem
Birefringence (double refraction): Weak (.009)
Crystal structure: Hexagonal
Treatments: This material is irradiated from clear Quartz. Some material is heated lighter, and there maybe other process involved, it is a trade secret.
What I prefer to polishing with: Cerium oxide with a Spectra Ultralap.
Jeff’s Comments: Cuts and polishes like any other Quartz, usually no problems. I like to use a 1200 Nu Bond lap for pre-polish, it makes the polishing stage faster and easier. Cuts an interesting stone especially in large sizes.
Design Notes: About any Quartz design will work well. As the rough gets more saturated. I prefer to cut large Quartz, they are actually pretty impressive, especially for material that costs almost nothing.
Design Links: 4-Way Stop – This is great for saturated rough if you have a piece that will work in the shape.
Be Still My Heart – Good in about any Quartz
CheckMate – Neat in medium color Quartz
Light House – Nice in any Quartz
Utopia – Classic Barion pear
