A small boutique buyer restocking birthstone pendants asked a simple question last spring: should they tie their spring display to amethyst or to rose quartz? Both sell, both read as "soft" on a mood board, and both sit in the quartz family the marketing team loves to mention. But the moment the order moves from a necklace to a ring, the two stones behave very differently. This guide walks through the color, hardness, and margin tradeoffs so a buyer can stock both without guessing.
Color range and what your shelf should actually carry
Amethyst is the purple variety of quartz. The trade grades it by tone and saturation: a deep, even Siberian purple commands a premium, while a pale lilac stone reads as a lower tier. Most commercial amethyst on the market today comes from Brazil and Uruguay, and a large share of it is heat-treated to deepen the color, which is permanent and accepted across the industry. Rose quartz, by contrast, is the pink to rosy variety of quartz, almost always cloudy or translucent rather than clean. Its value sits in the soft, even body color, not in clarity. The GIA gem encyclopedia entry on amethyst explains the hue/saturation/tone grading that wholesale parcels are sorted by.
For a shelf, that means amethyst should be merchandised by purple depth. A pale rose quartz pendant needs a brushed bezel to look intentional, while an amethyst stud needs good color face-up to justify the price. Rose quartz almost never appears as a clean faceted stone, so do not expect brilliance from it; expect glow. Cross-reference how you buy softer stones with our notes on which stones tolerate ultrasonic cleaning, because a quartz line you resell will eventually come back for cleaning.
Durability, hardness, and everyday wear
Both stones sit at 7 on the Mohs scale, which is comfortably above the 5.5-6 of a steel file and high enough for pendants, earrings, and occasional-wear rings. The difference is in fracture and chip resistance. Amethyst is often faceted and has sharp pavilion edges that chip if knocked against a counter. Rose quartz is usually cut en cabochon, rounded and smooth, so it wears like a polished pebble. A 7-rated ring stone will still scratch if it meets harder material like topaz or cubic zirconia, so set expectations with customers the way we describe in storage that prevents scratches and tarnish.
The practical stocking rule: put amethyst in earrings, pendants, and statement rings; put rose quartz in stackable bands and worry-free everyday rings. Neither belongs in a high-traffic wedding ring that sees dishwashing and gym sessions, though a cabochon rose quartz will survive far better than a faceted amethyst under those conditions. If a customer insists on an amethyst ring, spec it in a bezel that wraps the girdle.
Sourcing, price per carat, and margin
Amethyst prices move with color. A 10mm round faceted amethyst in a pale grade might cost a wholesaler a few dollars per carat, while a 6mm deep Siberian-color stone can cost several times that. Rose quartz is more uniform: supply is abundant, prices are steady, and the buyer pays mainly for cut and matching color in a strand. That predictability makes rose quartz a low-risk repeat order, while amethyst rewards a buyer who can sort parcels by color themselves. For pricing context, color quartz sits well below the colored corundum market, which is why it anchors accessible birthstone programs.
When you order a strand, ask for a photograph under a neutral 5500K lightbox rather than a phone photo, because phone cameras push purple too blue and pink too hot. Read more on how stones move from rough to retail in the gemstone supply chain from mine to retail.
FAQ: Amethyst vs rose quartz for stockists
Which one is the February birthstone?
Amethyst is the traditional February birthstone. Rose quartz has no official birthstone month, though it is heavily merchandised as a "love" or healing stone in lifestyle retail.
Do amethyst and rose quartz need special settings?
Faceted amethyst benefits from prongs or a protective bezel that covers the pavilion edge. A smooth rose quartz cabochon tolerates a simple prong setting because there are no sharp edges to chip.
Can both stones go in ultrasonic cleaners?
Quartz at Mohs 7 is generally safe in ultrasonic cleaning, but avoid heat and harsh detergents for dyed or heavily included material. Test one piece from a new parcel before bulk cleaning.
Which gives more predictable margin?
Rose quartz, because supply and color are consistent. Amethyst margin depends heavily on color grade, so a buyer who can sort parcels earns more.

Frequently Asked Questions
How do I verify a factory before placing a bulk order?
Request a production video, business license, export records and a paid sample run. A factory that accepts a 50-piece test order is usually a real manufacturer.
What payment terms do you offer?
30% T/T deposit with the balance against the bill of lading. This protects both sides on first orders and can move to net terms after a track record.
What is your normal reject rate?
3–5% under 10x loupe inspection for cast and set pieces. Defective units are replaced free in the next shipment.
Where is the factory located?
Wuzhou, Guangxi, China—the core lab-grown and moissanite manufacturing cluster. Shipments go via Guangzhou or Shenzhen ports.
