Peetambar & Kautubh Mani
The lord, appearing on the shoulder of Garuda, seemed like a cloud resting on the summit of the mountain known as Meru. The body of the lord was covered by attractive yellow garments (peetambar), and His neck was decorated with the jewel known as Kaustubha-mani. The bodily effulgence of the Lord dissipated all the darkness of the universe.” (Shrimad Bhagavatam, 4.30.5)
Thus Yellow garments mean Peetambar(peet-yellow, Ambar-clothes)
Kaustubh was the 4th gem which came from Sagar Manthana. And devas offered it to Shree Hari.
