how to create a resposnsive diamond shaped div with icons and border?

Question

I am trying to create a diamond shaped div with a border around it. but the problem i am facing is that it needs to be responsive and the shape is also unusual. attaching a image for reference.

I have created a custom icon font using icomoon app. The text next to the icon links also need to be responsive

My attempt so far:

.diamond {
  width: 60px;
  height: 60px;
  border: 1px solid #626262;
  margin-top: 20px;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  -o-transform: rotate(45deg);
  transform: rotate(45deg);
}
.diamond i {
  display: inline-block;
  margin: 0;
  -webkit-transform: rotate(-45deg);
  -ms-transform: rotate(-45deg);
  -o-transform: rotate(-45deg);
  transform: rotate(-45deg);
}
.diamond .top {
  margin-top: -10px;
  margin-bottom: 10px;
}
.diamond .bottom {
  margin-top: 10px
}
.diamond .top.left,
.diamond .bottom.left {
  margin-left: -10px;
}
.diamond .top.right,
.diamond .bottom.right {
  margin-right: -10px;
}
i.socialicn {
  color: #fff;
  padding: 6px 6px;
  background-color: #8a4d8e;
  border-radius: 50%;
  vertical-align: middle;
  font-size: 17px;
}
i.socialfb {
  color: #fff;
  padding: 6px 10px;
  background-color: #8a4d8e;
  border-radius: 50%;
  vertical-align: middle;
  font-size: 17px;
}

You could use something like:

.wrap {
  height: 20vw;
  width: 20vw;
  position: relative;
  margin: 50px auto;
  border: 5px solid black;
  transform: rotate(45deg);
transform-origin:top left;
  min-width:60px;min-height:60px;
}
.wrap a {
  position: absolute;
  height: 30px;
  width: 30px;
  background: tomato;
  border-radius: 50%;
  display: inline-block;
  text-align: center;
  text-decoration: none;
  line-height: 30px;
  transform: rotate(-45deg);
}
.wrap a:first-child {
  top: -15px;
  left: -15px;
}
.wrap a:not(:nth-child(3)) b{position:absolute; left:150%; width:auto;}
.wrap a:nth-child(2) {
  top: -15px;
  right: -15px;
}
.wrap a:nth-child(3) {
  bottom: -15px;
  left: -15px;
}
.wrap a:nth-child(4) {
  bottom: -15px;
  right: -15px;
}
.wrap a:nth-child(3) b{position:absolute; right:150%; width:auto;}

<div class="wrap">
  <a href="#">1 <b>Text</b></a>
  <a href="#">2 <b>Text</b></a>
  <a href="#">3 <b>Text</b></a>
  <a href="#">4 <b>Text</b></a>
</div>
