Stone Setting & Tightening

Our expert jewelers skillfully perform stone tightening and setting, an art form requiring precision and attention to detail. Stones are carefully placed in their settings to create a captivating appearance while attention is paid to tightening loose stones, ensuring long-lasting beauty and safety in the jewelry.

Prong Re-Tipping

Over time, the prongs holding gemstones in place may wear down, potentially leading to the loss of the gem stone. Prong re-tipping rebuilds or reinforces the prongs to secure the stones properly and prevent any risk of loss.
