We have bought many large parcels of assorted, natural fancy colored diamonds. In many cases, they include small stones. Small enough that they're less practical for rings, unless you're making a cluster.

We compile eclectic collections. In this case, we had a tiny hole drilled with a laser, so that the diamonds can be mounted to dangle on a chain.

They spackle a lovely pink blush.

All except the center pear shape - that one is crazy purple tinted! I love the combination of pink and yellow. Pink Lemonade Necklace, as it were...
