You can use a second div for the highlight to try and provide a stronger 3D effect, freeing up the box-shadow to be used for the darker contouring on the edges.
.circle {
width: 164px;
height: 164px;
background-color: #19f000;
border-radius: 100%;
position: relative;
border: 10px solid #444444;
box-shadow: 0 0 15px 0 rgba(0,0,0,.8) inset;
transform: rotate(-20deg);
}
.highlight {
position: absolute;
top: 2px;
right: 0;
left: 0;
margin: auto;
width: 80%;
height: 64%;
opacity: .92;
border-radius: 100%;

background: -moz-linear-gradient(top, rgba(255,255,255,1) 0%, rgba(255,255,255,0) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,1)), color-stop(100%,rgba(255,255,255,0))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* IE10+ */
background: linear-gradient(to bottom, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#00ffffff',GradientType=0 ); /* IE6-9 */
}
<div class="circle">
<div class="highlight"></div>
</div>

Answer 3

You can do with the combination of radial gradient and a pseudo element for glossy effect.
The transition from white to green can be produced through radial-gradient. The #fff color stops at 5%.
The glossy effect finish is given using the opacity on the pseudo element and has a similar shape of the parent with white background and reduced width.
JSfiddle Demo
.circle::after {
background: white none repeat scroll 0 0;
border-radius: 50%;
content: " ";
display: block;
height: 100px;
opacity: 0.15;
position: absolute;
width: 150px;
left: 20px;
}
.circle {
background-image: radial-gradient(ellipse at 50px 10px , #ffffff 0%, #fff 5%, #00ff00 100%);
border: 10px solid;
border-radius: 50%;
height: 200px;
position: relative;
width: 200px;
}
<div class="circle">
</div>

You can do it using a single element also by layering one radial-gradient image of the required size on top of an angled linear-gradient image and then positioning it appropriately. Multiple background images and layering has very good browser support (IE9+) but gradients are supported only in IE10+.
.circle {
border: 10px solid;
border-radius: 50%;
width: 200px;
height: 200px;
background: radial-gradient(ellipse at 90px 45px, rgba(255, 255, 255, 0.75) 10%, rgba(255,255,255,0.5) 30%, rgba(255,255,255,0) 32%, rgba(25,240,0,1) 45%), linear-gradient(160deg, transparent 12%, rgb(25, 240, 0) 30%);
background-size: 125% 80%, 100% 100%;
background-repeat: no-repeat;
}

Answer 6

Try box shadow like this: Updated Demo
Adjust the shadow values and background gradient colors according to your need.
.circle {
border:10px solid;
border-radius: 50%;
