Each product page lists that piece’s exact materials and available finishes — for example 14K white gold finish or 18K yellow gold finish over stainless steel. Finishes can photograph slightly differently than they appear in person, and screens vary — small tone differences are normal, not a defect.
The exact details for this piece are listed in the description above. Most keepsakes also come with a printed message card and arrive in a gift box.
