Crystal and gemstone retail is unique in that many products are individual natural specimens — no two pieces are identical in size, shape, weight, or colour. This creates product data challenges that differ from standard retail. Some retailers list each specimen as a separate product; others offer "similar to pictured" products by weight range. Migrating to Shopify requires deciding which approach works for your catalogue and ensuring the product data supports it.

Product categories

Raw/rough crystals: Natural specimens in their unmodified form. Sold by individual piece, weight category, or lot.
Tumbled stones: Polished, rounded stones. Often sold singly or by weight (100g bag, 500g bag).
Crystal points and clusters: Single-terminated, double-terminated, or cluster formations. Size and weight matter to buyers.
Crystal spheres and eggs: Shaped specimens. Diameter as key spec.
Gemstone cabochons: Polished flat-back stones for jewellery setting. Stone type, dimensions, carat weight.
Faceted gemstones: Cut stones for jewellery. Cut, carat, colour grade, clarity grade.
Crystal jewellery: Pendants, bracelets, rings. Stone type and setting material.
Mineral specimens: Collector minerals. Species, locality (origin), matrix/specimen type.
Crystal sets and kits: Curated collections (chakra sets, beginner crystal kits).

Individual specimen listings vs grade/size listings

Two approaches for natural specimens:

Individual listing: Each piece photographed and listed separately with its actual weight, dimensions, and unique image. Customer buys exactly what they see. Best for higher-value specimens (£20+) and collectors. Requires significant photography work but creates trust and reduces returns.
Grade/size listing: Products sold by weight or size category (Small: 30–50g / Medium: 50–80g / Large: 80–120g). Customer receives a piece "similar to pictured." Best for tumbled stones and lower-value raw pieces. Requires clear messaging that the exact piece varies.

product.metafields.crystal.specimen_type = "Individual / Grade (similar to pictured)"
product.metafields.crystal.weight_g = "187"                    // actual weight for individual
product.metafields.crystal.weight_range = "80-120g"            // for grade listings
product.metafields.crystal.dimensions_mm = "85x60x45"
product.metafields.crystal.origin = "Brazil / Madagascar / Morocco / Afghanistan"
product.metafields.crystal.mineral_species = "Amethyst / Quartz / Fluorite / Labradorite"
product.metafields.crystal.colour = "Purple / Lilac / Deep violet"
product.metafields.crystal.transparency = "Transparent / Translucent / Opaque"

Gemstone certifications

For higher-value gemstones (diamonds, rubies, sapphires, emeralds), certification from a recognised gemmological laboratory adds trust:

product.metafields.gemstone.carat_weight = "2.45"
product.metafields.gemstone.cut = "Oval / Round / Cushion / Emerald"
product.metafields.gemstone.colour_grade = "Heated / Unheated / Natural"
product.metafields.gemstone.treatment = "None / Heated / Beryllium / Fracture-filled"
product.metafields.gemstone.certification_lab = "GRS / GIA / AGL / Gübelin"
product.metafields.gemstone.certificate_number = "2023-GRS-12345"
product.metafields.gemstone.origin_certified = "Burma / Ceylon / Kashmir"

Crystal metaphysical properties

Many crystal retailers describe the metaphysical or energetic properties associated with each stone. UK regulations on health and wellbeing claims:

Crystal healing is not recognised by medical science — any claims that crystals treat medical conditions are prohibited
Describing associated "properties" in spiritual or traditional context (e.g. "historically associated with protection in many traditions") is generally acceptable
Avoid: "relieves anxiety," "cures insomnia," "heals emotional trauma" — these are therapeutic claims
Use: "often chosen for meditation focusing on calm and tranquillity" — intention-focused language

Bulk and wholesale sales

Many crystal retailers also supply wholesale (to other retailers, yoga studios, therapists). Options:

Wholesale collection or password-protected page with trade pricing
Customer tags + automatic discounts for verified trade accounts
Minimum order quantity: for wholesale products, display minimum order quantity clearly (e.g. "Minimum order: 10 pieces")

Post-migration checklist for crystals and gemstones stores

Individual specimens: each piece has its own product with actual weight, dimensions, and unique photos
Grade listings: "similar to pictured" clearly stated; size/weight range as metafield
Crystal origin (locality) as metafield on all specimens
Mineral species and colour as metafields
Certified gemstones: certification lab and certificate number as metafields
Treatment disclosure: heat treatment, filling, or no treatment clearly stated (consumer protection requirement)
Metaphysical claims: reviewed for compliance — no therapeutic health claims
Wholesale: trade pricing configured for B2B customers
Fragile packaging: notes in fulfilment instructions — crystals break in transit without proper packaging
