Border-radius around image causes image to get clipped

Can someone please help me with this CSS. The higher the border-radius I set, the worse the border gets clipped.

.sqs-image .sqs-image-content {
    border-width: 6px;
    box-sizing: border-box;
    border-style: solid;
      border-radius: 95px 95px 0 0;
    border-style: solid;
    border-image: linear-gradient(to right, @accent1, @accent2) 1;
}
