The primary difference between semi and pure dola silk saree lies in the ratio of silk to synthetic fibres, among other factors. The pure silk saree has relatively high ratio of silk fibres woven into the fabric as compared to the semi silk saree. Even within the pure dola silk saree category, there are numerous varieties, which directly impact the quality and price of the final saree.
In general, any pure silk saree offers greater luxury, quality, and natural beauty, and comes at a higher cost. A semi silk saree on the other hand, provides a more affordable and practical alternative with a similar appearance to pure silk but not the same level of grandness. The choice between the two depends on individual preferences, budget, and intended use.
