Metal Finder

Yellow, rose, white, or platinum. This is the fastest step — one look in her jewelry drawer usually answers it — and it hides the single best money trick in the whole process.

Your answer

Match the metal she already wears — people are fiercely loyal to their lane. If her everyday jewelry is gold-toned, buy yellow gold (and collect the warm-metal discount below). If it's silver-toned, the real question is platinum vs white gold: platinum if she has sensitive skin or you want zero upkeep; 14k white gold to save a few hundred up front and accept a quick replate every couple of years.

The drawer test

Her jewelry drawer says…
…buy this
Mostly gold tones
Yellow gold — riding a full-blown revival, zero maintenance (the color is the metal), and it unlocks the discount below. 18k for richer color if budget allows; 14k for harder wear.
Mostly silver tones
White gold (14k) or platinum — see the showdown below. Visually identical on day one.
Pink/rose tones, or she's "a little different on purpose"
Rose gold — flatters nearly every skin tone, toughest of the golds (thanks, copper), no upkeep, quietly romantic.
A genuine mix of everything
Two-tone: yellow or rose band with a white-metal head. Warm style, icy-looking diamond, costs nothing extra.
She's mentioned jewelry making her skin itch
Platinum, no debate. White gold alloys usually contain nickel; platinum is the hypoallergenic one.

Platinum vs white gold, settled in one table

The warm-metal discount (free money): yellow and rose gold reflect warmth into any diamond — a D-color and a J-color look equally warm in them. So warm-metal buyers can drop the diamond to I–J color and save 20–30% on the stone with zero visible difference. White metal buyers don't get this cheat; it's one of the best reasons to love her gold-toned drawer.
