Crystal Sphere Size Guide
This size guide is provided as a general approximation based on the type of crystal. Weight of the sphere may differ based on the density of the material. This size guide shows estimates up to our largest size, 10kg.
| Diameter in inches (mm) | Weight (grams) |
| 1 in. (25.4 mm) | ~ 100-150 |
| 2 in. (50.8 mm) | ~ 300-400 |
| 3 in. (76.2 mm) | ~ 600-800 |
| 4 in. (101.6 mm) | ~ 1000-1200 |
| 5 in. (127 mm) | ~ 1500-1800 |
| 6 in. (152.4 mm) | ~ 2200-2500 |
| 7 in. (177.8 mm) | ~ 3000-3500 |
| 8 in. (203.2 mm) | ~ 4000-4500 |
| 9 in. (228.6 mm) | ~ 5000-5500 |

| 14 in. (355.6 mm) | ~ 10000-10500 |
Crystal Pyramid Size Guide
This size guide is provided as a general approximation based on the type of crystal. Weight of the pyramid may differ based on the density of the material and angular cut of the slopes. This size guide shows estimates up to our largest size, 10kg.

| ~ 60 mm (2.4 in.) | ~ 300-400 |
| ~ 70 mm (2.8 in.) | ~ 500-600 |
| ~ 80 mm (3.1 in.) | ~ 700-800 |
| ~ 90-100 mm (3.5-3.9 in.) | ~ 900-1000 or 1kg |
| ~ 100-110 mm (3.9-4.3 in.) | 1kg-1.3kg |
| ~ 120-130 mm (4.7-5.1 in.) | 1.5-2kg |
| ~ 140-150 mm (5.5-5.9 in.) | 2.5-3kg |
| ~ 160-170 mm (6.3-6.7 in.) | 3.5-4kg |
