I understand that you want to display 2 dropdown if a product from a specified category, is added in cart. To achieve that, a have build for you a simple module.

First let's declare our module in /etc/modules/Namespace_CheckCategoryOnCart.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Namespace_CheckCategoryOnCart>
            <active>true</active>
            <codePool>local</codePool>
        </Namespace_CheckCategoryOnCart>
    </modules>
</config>

Next, in /app/code/local/Namespace/Namespace we have the following structure

/app/code/local/Namespace/Namespace/etc/config.xml

Contains

<?xml version="1.0"?>
<config>
    <modules>
        <Namespace_CheckCategoryOnCart>
            <version>1.0.0</version>
        </Namespace_CheckCategoryOnCart>
    </modules>
    <global>
        <helpers>
            <checkcategory>
                <class>Namespace_CheckCategoryOnCart_Helper</class>
            </checkcategory>
        </helpers>
    </global>
</config>

Helper class:

/app/code/local/Namespace/Namespace/Helper/Data.php

Contains

<?php
class Namespace_CheckCategoryOnCart_Helper_Data extends Mage_Core_Helper_Abstract
{
    public function hasProductFromCategory(){
        $cart = Mage::getModel('checkout/cart')->getQuote();
        foreach ($cart->getAllVisibleItems() as $item) {
            $categoryIds = $item->getProduct()->getCategoryIds();
            foreach($categoryIds as $categoryId){
                if($categoryId == "YOUR_RINGS_CATEGORY_ID"){
                    return true;
                }
            }
        }
    }
}

Now, in your cart.phtml you can check this condition using the following code:

if(Mage::helper('checkcategory')->hasProductFromCategory()){
      //show your dropdown
}
