How do I choose between a sideways cross and an upright cross?
Pick upright for a classic look, sideways for a modern one. An upright cross hangs vertically from the chain, while a sideways cross lies horizontally along the collarbone. Sideways styles tend to sit neatly under open collars and layer easily with other chains.
What do the carat total weight numbers on diamond crosses mean?
Carat total weight (ct. tw.) is the combined weight of all diamonds. A necklace with many small stones adds them together, so 1/10 ct. tw. is not one large diamond. Higher totals usually mean more or larger stones and more sparkle.
Should I choose 10K or 14K gold, or sterling silver?
Choose 14K for richer color, 10K for durability, silver for value. 14K gold has a higher gold content, while 10K is harder and well suited to daily wear. Sterling silver gives a bright white look and may tarnish over time. See our jewelry care tips.
Which diamond cross necklace styles are most popular?
Sideways diamond crosses and classic diamond crosses lead the list. Sterling silver and 10K gold versions appear often, along with cross and heart designs, mini crosses, and lab-grown diamond crosses in 14K gold. Curved bar and rounded stone styles also rank well.
