Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Some of them are effulgent like coral and diamonds in complexion and have garlands on their heads, blooming like lotus flowers, and some wear earrings.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There are some inhabitants who have attained the liberation of sarupya, or possessing bodily features like those of the Personality of Godhead. The vaidurya diamond is especially meant for the Personality of Godhead, but one who achieves the liberation of bodily equality with the Lord is especially favored with such diamonds on his body.
