6 Loose Diamonds to Create Bespoke Valentine's Day Jewels

By Sotheby's

B uying unmounted stones presents endless design possibilities, so when it comes to the holiday of love, why not gift a diamond which can be made into a one-of-a-kind treasure? Sotheby's Diamonds Online auction (30 January–7 February) features a curated mix of diamonds in an array of shapes and sizes, as well as colors ranging from purple to orange and even black. Out of the 20-plus stones on offer, we selected a few guaranteed to leave memorable impressions long after Valentine's Day.

1. Festive Hues

Pink and purple diamonds are extremely rare and sought after, and they are, of course, in keeping with the traditional, romantic color scheme of Valentine's Day.

2. Flawless and Foolproof

For those looking to impress, there is nothing better than a D color, Internally Flawless diamond. A classic round cut is also quite versatile, making this particular stone a fantastic investment.

3. The Perfect Pair

Although being offered separately, these two Fancy Purplish Pink diamonds would pair beautifully for earrings.

4. Delicate and Different

More peachy than rose, this Fancy Brown-Orange stone is a great option for those who are seeking colored diamonds in unusual hues.

5. The Nontraditionalist

It does not get more daring than this Fancy Black diamond, ideal for the alternative couple who is looking for something truly unique.

6. The Ultimate Symbol of Love

No Valentine's Day diamond list would be complete without a heart-shaped stone. It is believed that this specific cut became known during the 16th century when Mary Queen of Scots gifted a ring featuring a heart-shaped diamond to Queen Elizabeth as a sign of friendship.
