I am looking at an oval 3 stone engagement ring. The center stone is .81 E VS2, depth=66.6, table=61, 6.98x5.27. The side stones are .58 total weight, F VS2. The total price is $4500 (platinum settng). Two questions: is this a good deal? and is the proportion of center stone (.81ct) to side stones (.58ct) good? It's hard to tell since the stones are loose. Please help! Many thanks.
