A rough guideline on the stone size you will commonly see in our collections. 9-12 mm are typically stones cut from material and by carat is quite expensive so we   cut it in these smaller sizes to keep the price of a pendant within most budgets.   14-16mm stones are considered a smaller size stone and come in different shapes and dimensions. This size is popular for those starting out wearing our vibrational gemstone jewellery and will keep the price point at an entry level.  This stone size is often found set with a smaller second stone. 18-26mm are good medium size stones, these come in different shapes and dimensions. This stone range also is often set with a smaller second stone. 28mm and up are considered our larger size stones and do come in different shapes and dimensions.  These are also set with a smaller second stone.  The really big sizes 55mm for example are mostly set with just the main stone.
