All Masato strands are strung on silicon covered 0.4-mm stainless steel wire. Masato does not use silk—silk loosens, rots and is prone to string breaks. In addition to breaking easily, silk does not maintain the symmetry of the pearl strand leading to a jagged appearance women find very unattractive. Silicon covered wire is stronger and has a much better appearance around a woman’s neck, holding the natural form of a pearl necklace.
Masato inserts rubber rings between the back six pearls on either ends of the clasp protecting pearls from long-time wear. Our clasps are an original design made in-house by our pearl artisans with over 30 years creating custom jewelry clasps. Our clasp are made of 18k gold or platinum. Platinum clasp are made of high-grade 950 platinum.
