Who We Do Not Cater To

  • Jewelers requiring metals other than gold or silver (e.g., platinum, titanium, stainless steel)
  • Clients who do not provide at least 50% advance payment before production
  • Businesses seeking diamond-centered jewelry. (We only work with small accent diamonds as supporting stones—not as centerpieces.)
