Take it out and the whole thing comes down. Seemed like the right name for a plain band.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe face is brushed to a soft matte, so it wears quietly and hides the small marks a high polish would show off. The edges are bevelled and left polished, giving the ring a clean bright line around the finger without tipping into flashy. No inlay, no plating, no two-tone — just tungsten carbide, finished properly.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTungsten carbide sits at around 9 on the Mohs hardness scale, which makes it one of the most scratch-resistant materials used in jewellery. The finish isn't a coating, so there's nothing to wear through or peel. It holds its look through trades, gym sessions, washing up and everything else a wedding band gets put through.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eComfort-fit interior, so it slides on easily and sits flat without pinching. Available in 4mm for a slimmer profile and 6mm for a bit more presence — the two widths are cut to match, so they work as a pair.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eInterior engraving available: a date, initials, or a few words only the two of you will read.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBullets\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eTungsten carbide — around 9 on the Mohs scale, highly scratch resistant\u003c\/li\u003e\n\u003cli\u003eBrushed centre with polished bevelled edges\u003c\/li\u003e\n\u003cli\u003e4mm, also available in 6mm wide\u003c\/li\u003e\n\u003cli\u003eComfort-fit interior\u003c\/li\u003e\n\u003cli\u003eColour runs through the metal — no plating to wear off\u003c\/li\u003e\n\u003cli\u003eInterior engraving available\u003c\/li\u003e\n\u003cli\u003eFree silicone ring included with every order\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Forge and lumber","offers":[{"title":"I don't know - send free ring sizer","offer_id":58007688741246,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"I \/ US 4","offer_id":58007712137598,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"J \/ US 4.5","offer_id":58007712170366,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"K \/ US 5","offer_id":58007688774014,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"L \/ US 5.5","offer_id":58007688806782,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"M \/ US 6","offer_id":58007688839550,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"N \/ US 6.5","offer_id":58007688872318,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"O \/ US 7","offer_id":58007688905086,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"P \/ US 7.5","offer_id":58007688937854,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"Q \/ US 8","offer_id":58007688970622,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"R \/ US 8.5","offer_id":58007689003390,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"S \/ US 9","offer_id":58007689036158,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"T \/ US 9.5","offer_id":58007689068926,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"U \/ US 10","offer_id":58007689101694,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"V \/ US 10.5","offer_id":58007689134462,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"W \/ US 11","offer_id":58007689167230,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"X \/ US 11.5","offer_id":58007689199998,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"Y \/ US 12","offer_id":58007689232766,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true},{"title":"Z \/ US 12.5","offer_id":58007689265534,"sku":null,"price":368.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/0749\/8526\/files\/the-keystone-4mm-grey-stone.png?v=1789128680","url":"https:\/\/forgeandlumber.co.nz\/products\/the-keystone-4mm","provider":"Forge \u0026 Lumber","version":"1.0","type":"link"}
