The Gemstone Silver/Garnet is the newest release in what is considered Lane #1’s entry level line. The core/cover combination of this ball is the same as the original. The Hybrid ISO Pearl Reactive cover allows the Gemstone to glide through the front part of the lane for all styles on medium-dry to medium-oily conditions.

Cranker had the best success with the Gemstone on the medium test pattern, while Tweener and Stroker had the best look on our drier test pattern. Those with higher rev rates will benefit the most from the easy length this...

We experienced a slight read of the midlane with a strong arcing move at the breakpoint. The Gemstone is smooth down lane, making for an easy adjustment when the lanes break down.

The factory finish of the Gemstone provides easy length on medium and drier lane conditions. Those needing more traction in the oil can achieve it by knocking off the polish.

The strong arcing breakpoint keeps the Gemstone from covering too many boards at the back end. This is ideal on drier conditions as there is a large amount of friction provided by the lane.
Total Hook

The overall hook potential of this new Gemstone is several boards less than anything Lane #1 has in their current product line. This should be the choice for Lane #1 fans on drier conditions.

Strengths: What most will appreciate about the Gemstone is the use of a high performance cover that is not overpowered by a high performance core. This combination gives the Gemstone a strong read of the lane without going crazy when it encounters friction.

Weaknesses: The Gemstone will struggle on large volumes of oil. The core/cover combination just doesn’t create enough friction to handle heavy oil patterns. Surface adjustments will help on medium to oily patterns.

Overall Summary: This new Gemstone keeps the same price point as the original and maintains the excellent performance for the price tag. It will be most useful when the lanes offer plenty of friction and a ball with lots of hitting power is required.
