Necklace — Platinum & 18k Yellow Gold, Multicolored Tourmaline & Diamond

This necklace runs on contrast — the cool, dense weight of platinum set against the warmth of 18k yellow gold, with a run of multicolored tourmalines doing the work color alone can’t fake. Tourmaline is one of the only gems that occurs naturally across nearly the full color spectrum within a single mineral family, which is why a strand can hold pink, green, and blue without a dye lot or treatment note behind it. Diamonds punctuate rather than dominate, leaving room for the color to shift as the piece catches light.

Necklace — Platinum, 12+ Carat Diamond

Platinum is the setting of choice here for a reason: it’s denser and more wear-resistant than gold, which matters when the mounting has to hold a diamond weighing over 12 carats without competing with it visually. The supporting diamonds are set to recede into the metal, leaving the center stone to carry the piece on cut and clarity alone — no color accent, no secondary gemstone, just scale and light return.

Tiffany & Co. Schlumberger® Flowers and Stars Bracelet — 18k Yellow Gold & Platinum, Ruby & Diamond

Jean Schlumberger joined Tiffany & Co. in 1956, and his flower-and-star motifs have stayed in continuous production longer than most jewelry designs survive a single decade. This bracelet follows his signature approach: sculptural, dimensional settings that let a small cluster of stones read as a bloom rather than a pavé field. The rubies do the color work; the diamonds are structural, holding the star points in place.

Petals Unenhanced Peridot Ring

Unenhanced” is the operative word. Most colored gemstones on the market are heat-treated, oiled, or otherwise processed to improve clarity or color — peridot rarely needs it, and this ring’s grading leans into that fact rather than glossing over it. The Petals setting keeps the stone open to light from multiple angles, which is where an unenhanced peridot’s natural yellow-green actually shows its range.
