The practical difference
Sable is generally finer, lighter and more highly valued; marten can offer a related warm appearance at a different price level. Variation inside either category can still be substantial.

Comparison guide
Sable and marten can look similar at first glance, yet rarity, density, natural sheen, weight and grading place them in different value categories. Compare named material, construction and documentation—not colour alone.
Sable is generally finer, lighter and more highly valued; marten can offer a related warm appearance at a different price level. Variation inside either category can still be substantial.
Move the garment under neutral light, part the fur gently to view density, and compare weight, panel matching, lining and seams. Ask the advisor to identify the exact material and explain the accompanying documentation.
Choose according to budget, intended frequency of wear and the finish you genuinely prefer. A well-constructed marten piece may be a better personal choice than buying sable only for the name.
