Question 1

Is platinum good for engagement rings?

Accepted Answer

Yes. Platinum is strong, dense and naturally white, so it keeps its color without plating and holds a diamond securely through everyday wear. It is also a good choice for sensitive skin, because the platinum used in jewelry is usually around 95% pure. The trade-off is price: it costs more than gold.

Question 2

Is platinum better than white gold?

Accepted Answer

Neither is best for everyone, and both look white. Platinum stays white on its own, is heavier and suits sensitive skin. White gold gets its bright white from rhodium plating, which wears slowly and needs renewing every so often, but it costs less. Choose platinum for low upkeep, white gold for a lower price.

Question 3

How much does a platinum oval engagement ring cost?

Accepted Answer

A platinum ring costs the setting plus the diamond. Platinum settings cost more than gold: platinum is denser, so each ring uses more metal, and it is harder to work. The diamond is priced by carat and grade: in our stock, a 2 carat oval costs about one and a half times a 1 carat of the same grade.

Question 4

Does platinum scratch or change over time?

Accepted Answer

Platinum does scratch, like every metal, but it doesn't wear away the way gold does. Instead, the metal moves aside and forms a soft, satin sheen called a patina. Some people love the patina; others have it polished back to a mirror shine. Either way, platinum never needs re-plating.

Question 5

What color diamond looks best in platinum?

Accepted Answer

Because platinum is bright white, it shows a diamond's true color. A colorless (D to F) or near-colorless (G or H) diamond keeps the whole ring looking icy white. A warmer stone can look slightly yellow next to platinum, so it is worth staying at H color or better.

Question 6

What size oval diamond should I choose?

Accepted Answer

Choose by the size you want to see on the hand, not only the carat weight. A white platinum setting blends with the diamond, so the stone can look a little bigger than it would in yellow gold. Compare stones by their length and width in millimeters. Typical sizes of the oval lab grown diamonds in our stock:

1 carat — about 8.3 × 5.6 mm
1.5 carat — about 9.2 × 6.4 mm
2 carat — about 10.3 × 7.1 mm
3 carat — about 11.8 × 8.1 mm
4 carat — about 12.8 × 9.0 mm
5 carat — about 14.4 × 9.6 mm
