Dear Utkarshsingh,

 Thank you for your posts.

 Not enough people have the skill nor time to make the detailed basics (objects and props), that form the foundations of more complex renders and scenes.

 Your necklace, along with your mono-shock are good clean and accurate contributions.

As to "simple" ... the most glamorous ladies and models prefer simple elegant styles - like the necklace you have made (very good).

 May be worth your time to visit the tutorial section here - and read/watch some of the (free) guides provided by Mike, Ion and others.

 This will help you create and present truly professional finished renders of your designs.

 Keep well and keep safe,

 Rick.
